How quantum computing is already used in Russia - TA opinions

• is Quantum computing one of the key areas of technological development Russia supported by state the Quantum Digital economy Computing program and roadmap. The document expires at the end of 2024, and in the future quantum technologies will develop within the framework of the new national project "Data Economics and Digital Transformation." states quantum computing TAdviser In November 2024, he talked about Russia's achievements in the field with the main participants in this market.

Director of the Institute of Physics and Quantum Engineering at MISIS University, co-founder of the KuBoard project Alexei Fedorov says that the main result of the implementation of the roadmap for quantum computing was the creation of a 50-qubit quantum computer based on ions by the Russian Quantum Center and FIAN named after P.N. Lebedev. In addition, by the end of 2024, various pilot projects are being carried out to introduce quantum computing on the basis of the Russian Quantum Center and KuBoard, Fedorov said.

To implement quantum computing, there are four main platforms: superconductors, ions, neutral atoms and photons. Russia has already mastered all of them

According to him, quantum developments are already useful in scientific and educational activities: technology helps to conduct research and educate students. Also beneficial are pilot projects that are being done in order to identify the potential from the introduction of quantum computing.

We did such projects for the nuclear industry, medicine, telecommunications, oil and gas, production companies, etc. At the same time, one of the "intermediate" victories may be in the introduction of so-called quantum-inspired algorithms that emulate the behavior of quantum objects on classical computers and can show opportunities for more efficient solution of problems, say, from the field of optimization, - said Fedorov.

Rosatom stressed that a universal quantum computer on an ion platform with 50 qubits by November 2024 is the most powerful quantum computer in Russia. It is accessed through a cloud platform with which basic quantum algorithms can be launched. The state corporation added that by the end of 2024, three (or even more) different quantum computers with a capacity of 50 qubits can be created. More information about the quantum developments of Rosatom is described in this article.

The head of the research department " listed several examples of the use of quantum technologies in the Russian Federation. According to the expert, Genotek uses quantum computing to assemble the genome, a method for restoring the sequence of DNA structure based on short fragments of genetic information obtained during genome sequencing. RN-BashNIPIneft optimized the routes of repair teams using quantum computing, and Gazprombank was one of the first among financial organizations to test quantum cryptography tools to protect communication channels between data centers, Surkov said.

According to Maxim Ostras, General Director of the Russian Quantum Center, project manager of the Russian Quantum Center for the use of quantum sensors in medicine, Head of QLU, by the end of 2024, the main work in this direction is aimed at investigating potential applications of quantum computing in various fields, including big data and optimization, which will allow you to implement more complex models in the near future and find hidden patterns in large amounts of information.

In the near future, software and hardware platforms will be useful for solving optimization, planning, predictive and prescriptive analytics problems for making optimal decisions, which at the current stage will use hybrid (quantum-classical) and quantum-inspired algorithms and solutions running today (including in emulation mode) on classic computers (CPU, GPU, FPGA), said Yaroslav Borisov, director of business development at SP Kvant LLC (Rosatom - Quantum Technologies).

As Natalia Maleeva, director of the design center for quantum design at MISIS University, told TAdviser, Russia is one of the three countries that have already created quantum processors based on all four main platforms: superconductors, ions, neutral atoms and photons. According to Maleeva, quantum computing by November 2024 can be run on Russian processors, the first quantum algorithms are already being implemented on ion and superconducting quantum processors.

In 2024, MISIS specialists on a superconducting processor performed the first algorithm in the interests of an industrial partner (the name of the company is not disclosed at the university), which, as Natalia Maleeva emphasized, is a very important stage in the transition of quantum technologies from scientific laboratories to the industry.

In addition, the first quantum machine learning algorithms were successfully implemented on both the ion and superconductor platforms in 2024. The hybrid quantum-classical neural networks implemented in this way have shown, in particular, that the hybrid neural network is more resistant to noisy input data than the classical one, which can be very useful in analyzing poor quality data, said the director of the quantum design center at MISIS University.

The head of the quantum computing sector at the Quantum Center Research Institute MTUSI Evgeny Burlakov reported on several quantum projects that are already finding practical application in business. Thus, the Russian Quantum Center provides cloud services that allow companies to test quantum algorithms to optimize logistics and data analysis. These services run on quantum computer simulators that mimic the behavior of real quantum systems, as well as experimental quantum devices developed as part of national projects.

According to Burlakov, Sberbank actively uses quantum technologies to predict financial risks and client analytics, using quantum processors available in the cloud. Thanks to the SberCloud platform, companies can launch quantum computing remotely: access is provided through cloud interfaces, which eliminates the need to purchase expensive equipment and create their own technical infrastructure.

Burlakov said that cloud quantum platforms are also used to solve specific problems, such as modeling chemical processes, which is especially in demand in pharmaceuticals and power. These platforms run on hybrid architectures, where quantum processors are complemented by classical computing power for data preprocessing. In addition, quantum algorithms are already being used in machine learning, big data analysis, and combinatorial optimization problems. Such technologies are actively introduced in industries such as logistics, production process management and power, allowing companies to achieve high calculation accuracy and significant resource savings.

The head of the Educational and Scientific Center "Quantum Engineering" NRNU MEPhI Yana Lyakhova said that in the Russian Federation quantum-inspired algorithms are successfully used in practice - these are classical computational algorithms created with borrowing ideas from quantum physics. In particular, such developments are used to optimize the investment portfolio, find the best supply chains and optimize a number of production processes. In different cases, the gain from the use of such algorithms ranges from several units to ten percent, she added.

Stanislav Straupe, senior researcher at the Center for Quantum Technologies, Faculty of Physics, Moscow State University, notes that quantum devices in Russia and the world that exist by the end of 2024 are not yet perfect enough to surpass conventional computing systems in practical tasks. Here it is necessary to work both on improving the hardware (more qubits, higher accuracy of logical operations, error correction, etc.) and on the development of algorithms with more gentle equipment requirements, the expert believes.

By the end of November 2024, the national project "Data Economics" has not yet been approved, and the planned spending on the direction of quantum computing is unknown. Evgeny Burlakov from MTUSI said that the financing of quantum projects in Russia by the end of 2024 will exceed 24 billion rubles, including state and extrabudgetary funds. These investments are aimed not only at developing quantum processors, but also at creating software and simulators, he said.

Scientists have created a 50-qubit ion quantum computer

Russian scientists, with the support of Rosatom, have created a 50-qubit ion quantum computer. Rosatom announced this on September 26, 2024. Read more here.

At the Moscow State Technical University named after N.E. Bauman built "Quantum Park" for the development of quantum technologies

At the end of August 2024, it became known that the Moscow State Technical University named after N.E. Bauman about the completion of the construction of the Quantum Park, designed to develop quantum technologies. The facility has become a key part of the university's new science campus.

The state spent 24.1 billion rubles on the development of quantum technologies in Russia in 2020-2024

State investments in the development of quantum technologies in Russia in the period from 2020 to 2024 amounted to ₽24,1 billion. This became known at the end of August 2024 from a study prepared by Reksoft Consulting.

These funds are aimed at implementing an ambitious program for the development of quantum computing, coordinated by the state corporation Rosatom within the framework of the federal project "Digital Technologies" of the national program "Digital Economy." During this period, the government annually allocated about ₽4,8 billion to create the conditions necessary to form the quantum computing market.

This program involved government agencies such as the Ministry of Communications, the Ministry of Economic Development and the Ministry of Education and Science, as well as large commercial organizations, including Gazprombank and Sberbank. The scientific base for the development of quantum technologies in Russia is formed by leading research centers, including the Russian Quantum Center, the Center for Quantum Technologies of Moscow State University and NUST MISIS.

By August 2024, quantum machines with various architectures were developed and operate in Russia. Among them are 16-qubit systems based on ion traps and neutral atoms, an 8-qubit superconductor processor, and a 4-qubit computer built on photon chips. However, the number of qubits in Russian processors remains limited, which makes them suitable only for experimental calculations. Full-scale industrial quantum computers in Russia are expected no earlier than 2028-2030.

According to analysts at Reksoft Consulting, the quantum computing market in Russia is in the early stages of its formation. The number of companies shaping demand for these technologies is small, making it difficult to determine real market volumes. However, the main investments come from the state, which creates the necessary conditions for the future growth of this high-tech area.

Scientists have improved the effectiveness of simulating noisy quantum chains using classical computers

Researchers at MISIS University, the Russian Quantum Center (RCC), the Moscow Institute of Physics and Technology (MIPT) and the Mathematical Institute named after V.A. Steklova found out how to increase the efficiency of simulating quantum computing on classical computers in noise conditions. MISIS announced this on August 2, 2024.

To solve this problem, scientists considered the so-called quasi-probabilistic representation of quantum mechanics, in which the behavior of quantum objects can be described using "negative probabilities" (quasi-probabilities).

Within a quasi-probabilistic representation, the possibility of negative probabilities is the only difference between quantum systems and stochastic classical systems. The more negative elements in the quasi-probabilistic description of the implementation of a quantum algorithm, i.e., the greater its negativity, the more, in turn, the addition to stimulate this algorithm on a classical computer.

Thanks to this developed technique of selecting the most suitable "basis" - the so-called generalized frame - for building a quasi-probabilistic description of a specific quantum chain, the authors demonstrated the possibility of reducing the negativity of this chain, which simplifies its classical simulation.

The study includes an analysis of quantum circuits in which noisy one-bit and two-bit quantum gates are present. Quantum gates are similar to logic gates in conventional computers, but can operate on quantum states that include quantum superposition states and entangled states. In real modern quantum processors, these valves are subject to various kinds of noise, which leads to the destruction of the processed quantum information, - said Alexey Fedorov, director of the Institute of Physics and Quantum Engineering, NUST MISIS, head of the scientific group "Quantum Information Technologies" RCC.

The minimization of overall negativity was carried out for different combinations of frame dimension and valve type, which made it possible to identify optimal parameters for different noise levels. Using the optimization algorithm, one-bit frames of different dimensions corresponding to possible three-dimensional regular polyhedra (tetrahedron, cube, octahedron, etc.) were considered. Each polyhedron was considered inside the three-dimensional space of Bloch parameters, and its vertices served as points for the construction of single-byte frames. The authors of the article showed that the transition to polyhedra with a large number of vertices - an increase in the dimension of the frame - provides a decrease in negativity in the corresponding quasi-probability description of the chain. The results were compared with an alternative method of reducing negativity by combining several gates into one (gate merging). It turned out that in the presence of noise, increasing the size of frames leads to a more effective reduction in negativity compared to combining gates. The results of the study are published in the scientific journal Physical Review A (Q1).

The results of the study are important for the effective classical simulation of current generation quantum devices in which operations are subject to noise. We have shown that by increasing the dimension of the frames on which quasi-probabilistic representations are built, it is possible to significantly reduce negativity, thereby accelerating the classical simulation of quantum calculations. In the future, we plan to use quasi-probabilistic simulation techniques to increase the efficiency of quantum computing and the ability to execute large quantum chains on current quantum computers, "said Denis Kulikov, junior researcher at the Quantum Information Technologies Group of the RCC.

The work was carried out with the financial support of the Russian Science Foundation (project No. 19-71-10091), as well as as part of the implementation of the strategic project NUST MISIS "Quantum Internet" under the program of the Ministry of Education and Science of Russia "Priority-2030."

Quantum processor with record accuracy of algorithms launched in Russia

Russian scientists presented the latest quantum processor, which demonstrated record performance of algorithm execution accuracy. This became known on June 25, 2024. The processor was developed at the scientific and educational center "Functional Micro/Nanosystems" on the basis of the Moscow State Technical University named after N. E. Bauman and the All-Russian Research Institute of Automation (VNIIA) named after N. L. Dukhov.

Putin gave instructions on training personnel in the field of quantum technologies

On June 21, 2024, Russian President Vladimir Putin gave instructions on training personnel in the field of quantum technologies. Such decisions are expected to help ensure Russia's technological independence and leadership.

In April 2024, Ivan Utenkov, a member of the board of the Russian Union of Industrialists and Entrepreneurs (RSPP) (Unmanned Technologies group of companies), pointed out the lack of personnel and low qualifications of specialists in the sectors of quantum technologies, robotics and drones. It is estimated that in 2022 the shortage of engineers in the field of quantum technology was about 1000 people, and in 2023 the shortage of personnel increased. It was proposed to create a consortium for the training of quantum engineers on the basis of the Russian Union of Industrialists and Entrepreneurs - this idea was supported by Putin.

Vladimir Putin

In accordance with the new instruction of the head of state, the issue of creating a consortium for training personnel in the field of quantum technologies should be considered with the participation of the Russian Union of Industrialists and Entrepreneurs and other interested organizations. It is assumed that the consortium will unite "representatives of the business community and leading educational organizations of higher education."

It is noted that quantum computing gives impetus to the digital development of the country, since it provides a higher speed of data processing compared to conventional computers. At the same time, quantum solutions set completely new requirements for information security. In Russia, by 2030, it is planned to build at least 15 thousand km of trunk channels of quantum communications in key areas, as well as create centers for monitoring the quantum network.

I consider it necessary to continue work on quantum communications and quantum encryption technologies. Such technologies ensure the resistance of information systems to cyber attacks using both classical and quantum computers, Putin said earlier.[1]

Scientists from Russia, Germany and the UAE have found a way to simplify quantum calculations using fractality

An international team of physicists from Russia, Germany and the UAE has shown that one of the main theories for assessing the capabilities of quantum technologies - the Schwinger model - has fractal properties. As representatives of MISIS told TAdviser on May 24, 2024, this unusual and beautiful property of self-similarity will help simplify and speed up calculations when creating an improved quantum processor capable of solving problems in the field of logistics, machine learning and cryptography.

Schwinger's model was developed in the 1950s. According to scientists, despite the fact that this is one of the basic and well-studied theories, it has a number of non-trivial features inherent in more complex theories. Analytically, it is solvable in particular cases of massless or non-interacting particles, but in the general case the solution is unknown, so the model is a difficult problem for both analytical and numerical methods.

According to the researchers, the identification of a specific structure in a quantum system of many bodies can provide valuable information to simplify its description. As, for example, a self-similar structure that arises when describing complex quantum systems consisting of a large number of components. Quantum systems such as the Heisenberg and Ising models, which describe, for example, the magnetic properties of materials, have fractal properties. Fractality was identified using visualization on 2D graphs.

Scientists have shown for the first time that the Schwinger model also has fractal properties. Based on this, a method was proposed for calculating the properties of the Schwinger model, when a description with a smaller number of particles is taken as a basis for calculating a system with a large number of objects. This method of calculation - ansatz - has shown its effectiveness.

"Previously, in the Schwinger model, no self-similar structure was observed in the ground state. Based on the exact solution for a small system, we construct a description for a system with a large number of particles using a fractal ansatz approach. Our method is very effective. We believe that it can also be applied to a wider class of models, "said study co-author Alexei Fedorov, director of the Institute of Quantum Physics at NITU MISIS, head of the Quantum Information Technologies scientific group at the Russian Quantum Center.

Alexey Fedorov, Director of the Institute of Quantum Physics, NITU MISIS, Head of the Scientific Group "Quantum Information Technologies" of the Russian Quantum Center

According to the authors of the study, published in one scientific journal Physical Review Letters (Q1), the most ambitious direction of development of the created model is to go beyond a one-dimensional system and establish self-similar patterns for two-dimensional and three-dimensional systems. This, in turn, will improve the production of quantum processors based on multi-level qubits.

The work was supported by the state corporation Rosatom within the framework of the Roadmap for Quantum Computing, a grant from the strategic project NUST MISIS "Quantum Internet" under the program of the Ministry of Education and Science of Russia "Priority-2030" (No. K1-2022-027), a grant from the RNF, as well as the Deutsche Forschungsgemeinschaft (DFG, Research Foundation of Germany) under the German academic leadership program Excellence Strategy.

Rosatom will use quantum technologies to transform government agencies

On May 22, 2024, it became known that the state corporation Rosatom sent proposals to the Ministry of Ministry of Digital Development regarding the use of quantum technologies for the transformation of government agencies. It is assumed that this will stimulate the demand for such solutions in Russia.

According to the Vedomosti newspaper, the initiative is being worked out within the framework of the national project "Data Economics and Digital Transformation of the State." Rosatom proposes to include the use of quantum technologies in "methodological recommendations for the digital transformation of federal executive bodies and management bodies of state extra-budgetary funds, state corporations and companies with state participation."

Rosatom sent proposals to the Ministry of Digital Development regarding the use of quantum technologies for the transformation of government agencies

It is assumed that quantum technologies will be used to solve complex optimization problems related to planning, forecasting, development of new materials and strengthening the capabilities of AI. Aleksey Naumenko, deputy director of technology practice at Kept, believes that quantum systems in the public sector will ensure reliable protection of channels for transmitting sensitive information and data containing state secrets. In particular, Russian Railways is engaged in the development of quantum communications tools. Quantum sensors are named another promising field of application.

It is noted that as of May 2024, quantum technologies are tested in Russia primarily by the structures of the banking sector, telecom companies, defense industry enterprises, as well as companies responsible for the implementation of the roadmap for the development of quantum technologies (Russian Railways and Rosatom). At the same time, experts say, the introduction of quantum developments in the business sphere is fraught with a number of difficulties. Thus, the full use of such technologies is impossible without control from regulators, in particular, the FSB.^[2]

Russian scientists have developed "digital twins" to control quantum systems

MISIS Russian Quantum Center (RCC) The researchers of the University and developed, control model of complex quantum systems which, according to them, opens up opportunities for faster transmission information and allows you to control the dynamics of the system. This was announced on May 16, 2024 by TAdviser representatives of MISIS.

According to the scientists, the proposed technique is useful for reducing the number of errors and suppressing noise in quantum devices. With its help, it will be possible to study various effects in the physics of many bodies, as well as look for new quantum materials. Modification of the model will allow observing systems at the macroscopic level, which, in turn, opens the way to controlling quantum systems between different phases of matter. Read more here.

According to them, this method brings closer the creation of a practically useful "noisy" quantum processor and algorithms for efficient multi-cube operations. Quantum effects, in turn, are useful for studying molecules, creating drugs, effectively solving logistics problems and searching the database. Read more here.

ITMO figured out how to increase the lifetime of quantum states

ITMO scientists have figured out how to create long-lived quantum states for processing, stable recording and reliable storage of information. The solution is based on artificial intelligence. In the future, the results of the study will help in the creation of quantum computers. The university announced this on April 3, 2024.

To solve complex computational problems (for example, encrypting information using quantum cryptography), scientists are working on the creation of quantum simulators (computers). Unlike usual, such a device does not use bits (work with two states: 0 and 1), but qubits (can work with a large number of states). It is believed that thanks to this, quantum computers will be able to process all states at the same time and deliver solutions faster than conventional PCs.

One of the main technical obstacles faced by researchers in the development of a quantum computer is spontaneous radiation, when a unit of information recorded in the system (qubit) can collapse at any moment in time, radiating into the surrounding space. This phenomenon often limits the lifetime of quantum states and, in fact, makes recording data in quantum systems impossible. Large atomic structures (of tens or hundreds of atoms) are commonly used to suppress spontaneous radiation. Previously, scientists have already found optimal two-dimensional atomic lattices capable of maintaining the longest-lived states, but what the optimal design of structures of arbitrarily arranged particles should be remained unknown.

This time, physicists from ITMO managed to obtain structures that retain a quantum state tens and hundreds of times longer using a small optimization of geometry. To do this, they applied evolutionary algorithms (a direction in artificial intelligence that simulates the processes of natural selection) and created a program that predicts the appropriate parameters of systems. Unlike many other works, where atomic structures had a predetermined geometry in advance, in this work artificial intelligence itself found the necessary positions of atoms.

This solution determines the geometry of molecules from ultracold atoms. In fact, scientists wrote instructions for assembling durable quantum systems for recording and storing information. Artificial intelligence-predicted structures can be used to create quantum memory algorithms.

The authors considered two changing parameters: the number of atoms and the minimum allowed distance between them. Using the algorithm, they determined the optimal geometric arrangement of particles for different interatomic distances: one-dimensional chains, fragments of triangular and square lattices. All these configurations are capable of supporting non-emitting, and therefore long-lived quantum states.

There are two ways of developing this work. If earlier we calculated the parameters of structures for single-photon states, then we will continue to look for the same for two-photon entangled states: you can write twice as much data in them, and also use them in quantum communication to transmit information. In addition, we would like to improve our algorithm so that we can count systems from a larger number of atoms, "said Ilya Volkov, one of the authors of the work, a graduate student at the New Physics Department.

The results of the work will allow experimenters to increase the recording time of quantum states - this will open up new opportunities for working with them, including helping to create quantum computers.

Russian scientists have proven the effectiveness of three-level quantum systems - cutrites

Scientists of the University of MISIS, the Russian Quantum Center, FIAN named after Lebedev and MIPT demonstrated the performance of three-level quantum systems - cutrites at once on two types of domestic quantum processors - superconductor and ion. With the help of cutrites, the researchers simulated a non-equilibrium phase transition of violation of parity and time symmetry. Such symmetry is broken if an isolated physical system begins to interact with the surrounding world, while losing some of its energy. This was announced on April 1, 2024 by representatives of the University of MISIS. Read more here.

In Russia, approved standards in the field of quantum communications

At the end of February 2024, it became known about the approval of two new standards in the field of quantum communications. They were told in the press service of the Platform of the National Technological Initiative (NTI).

One of the new standards concerns the architecture of a typical firmware key distribution complex, which provides secure key delivery to quantum Internet of Things devices, the direct connection of which to quantum key distribution networks is technically impossible or impractical.

It became known about the approval of two new standards in the field of quantum communications

In the second standard, we are talking about setting the requirements for the connection interfaces of a typical software and hardware complex for key distribution in terms of interaction with a quantum key distribution network, as well as interfaces for transmitting quantum and quantum-secure keys to quantum Internet of Things terminals.

According to the NTI Platform, the standards began to operate on February 1, 2024. The documents are designed for three years. Nikita Utkin, Deputy Director of ANO Platform NTI, Chairman of TC 194 Cyber-Physical Systems, noted that the standards pave the way for the widespread practical introduction of quantum technologies, in particular, quantum key distribution, in various fields of activity: from the banking sector to the industrial Internet of things and consumer smart systems.

For us, working on these documents was extremely important from several points of view: firstly, this is a charismatic example of the implementation of the principle of advanced regulation in the field of high technologies, secondly, this is an example of extremely difficult collective work and reaching an industry consensus, and thirdly, these standards consolidate the fact of the existence and transition to the practical channel of an extremely promising technological market, in which Russian developers have very serious groundwork, - said Utkin.[3]

Russia has learned to create triangular and rectangular laser pulses - this will improve the control of quantum circuits

In mid-January 2024, Russian researchers from St. Petersburg State University and the A. F. Ioffe Institute of Physics and Technology of the Russian Academy of Sciences (St. Petersburg) announced the development of a method for obtaining optical pulses of adjustable shape. In the future, this is expected to help improve the management of quantum computers.

In ordinary light pulses, the intensity of the electromagnetic field varies with time along the sinusoid. It was believed that other forms of the field were impossible. Russian physicists have proposed an approach that allows you to create rectangular and triangular light pulses.

The scientists simulated the passage of two consecutive ultra-short optical pulses through sodium gas. The primary pulses had an arc shape that corresponds to half the period of a conventional electromagnetic wave. In accordance with the proposed model, pulses passed a path of 5 micrometers in the medium. At the same time, the first of them transmitted excitation to sodium atoms, triggering their vibrations, and the second stopped them. As a result of this interaction, an electromagnetic field response was formed in the form of two peaks spaced in time.

Next, the researchers proposed using a heterogeneous density environment with a varying concentration of sodium particles. Experts, in particular, applied a trapezoidal model: at the borders, the density was minimal, as it moved away from them, it increased linearly, and in the center it reached a plateau. As a result, it was possible to obtain strictly rectangular pulses. By changing the shape of the medium density transition at the rise and fall sites from linear to parabolic, the researchers were able to form triangular pulses. With such pulses, it is possible to control the state of individual atoms and qubits - the elements underlying quantum computers.^[4]

Bauman and FSUE "VNIIA named after N.L. Dukhova" proposed and demonstrated a method for implementing a fast two-cube operation on superconducting qubits-flaxoniums, which can form the basis of scalable and error-resistant quantum processors. Thus, Russian scientists have become one step closer to creating a universal quantum computer capable of solving problems in various fields, for example, for modeling molecular and chemical reactions, which will be the key to the further development of pharmaceuticals and materials science. Such information was shared with the TAdviser portal on November 27, 2023 by representatives of MISIS. Read more here.

Rostec abandoned the development of the Quantum Sensors roadmap that lasted several years

Rostec abandoned the development of the Quantum Sensors roadmap that had lasted several years. This became known on October 2, 2023.

The need for an agreement has formally disappeared. The activities of the "roadmap" are already being implemented within the framework of the state program for the development of the electronic and radio-electronic industry and will continue to be implemented, including by Rostec, - one of the sources told RBC.

According to him, the initiator of the termination is Rostec itself. At the same time, we are talking about a technical solution, which there is no intrigue, the source added.

Rostec proposed spending 41 billion rubles on the creation and development of the quantum sensor market, of which 27 billion rubles were budget, 14 billion rubles of its own funds and other investments. The roadmap describes 19 types of sensors, ten of which were supposed to be prepared for industrial production by the end of 2024.

According to a RBC source in the IT market, quantum sensors can be included in documents on the development of directions quantum computing and quantum communications, which will be created as part of the Data Economics project until 2030. Its development will be engaged in "" and Rosatom- RUSSIAN RAILWAY each in its part. The government must approve the national project "Data Economics" by June 2024.

According to Vedomosti, Sensors are one of the most promising areas of the quantum technology market. Quantum sensors will allow ultra-accurate measurement of various physical quantities - time, distance, speed, etc. Such sensors can be used in satellite and ground communication systems, as well as on cellular networks.

A new university and the development of encryption technologies. Putin gave instructions on quantum technologies

On September 4, 2023, a list of instructions from Russian President Vladimir Putin following a meeting with scientists and a plenary meeting of the forum for future technologies was published on the Kremlin's website. In particular, we are talking about the development of quantum technologies.

Until November 15, 2023, the government was instructed to create conditions for attracting domestic and foreign scientists and qualified specialists in the field of quantum technologies to the Russian Federation, including in the development of quantum sensors, quantum computing and communications, including simplification of the visa regime, obtaining a residence permit and citizenship of the Russian Federation, procedures for execution of documents required for migration registration and admission to work, as well as the development of mechanisms for individual material support and ensuring the social and domestic arrangement of such persons and their families.

Also, the Cabinet of Ministers to create a university in the field of quantum technologies in order to implement educational programs to study advanced developments in this area, including those involving schoolchildren in the educational process.

The university will also support scientific research and innovative projects in quantum technology. This includes working with scientific institutes, industry and government agencies to develop and implement quantum technologies in real-world practice.

The initiative to create a university in the field of quantum technologies emphasizes the importance of developing this area as one of the priorities for the scientific and technical development of Russia.

Algorithms have been created in Russia to help secure computers from quantum cyber attacks

At the St. Petersburg State Electrotechnical University "LETI" created a way to protect computers from quantum cyber attacks. The university told about this in July 2023.

According to university analyst Alexei Petrenko, LETI specialists have developed new algorithms that allow modeling cyber attacks using super-powerful quantum computers on digital infrastructure and finding vulnerabilities in it for their subsequent elimination. Algorithms for analyzing encryption systems work according to symmetrical and asymmetrical principles - in the first case, the same digital key is used to encrypt and decrypt a message, in the second - different ones. The use of such algorithms will reduce the computational load when searching for vulnerabilities in encryption systems and speed up the work of cryptanalysts.

In our research, we are mainly engaged in quantum cryptanalysis and, as a result, create more robust post-quantum algorithms. Modifications of quantum algorithms can be roughly divided into mathematical, structural and implementation. In our work, we used all three areas, after which we tested and received significant acceleration compared to the original algorithms for solving a number of problems, "he told TASS.

LETI noted that by July 2023, effective quantum algorithms are widely known, in particular, the Shore and Grover algorithms, which are quite effective and convenient for cryptanalysis of asymmetric and symmetric cryptography, respectively. However, they are not the only ones suitable for cryptanalysis, which allows them to be used comprehensively with other, more narrowly directed quantum algorithms. Symmetric cryptography is one type of data encryption in which the same key is used for both encryption and decryption, while asymmetric cryptography involves the use of two keys - public (used to encrypt information and can be transmitted over unprotected channels) and private (used to decrypt data encrypted with a public key). Scientists have modified these promising quantum algorithms in order to reduce their computational complexity and time.^[7]

The Government of the Russian Federation has developed measures to support developers of quantum technologies

On July 21, 2023, it became known that the concept of the development of the Russian quantum industry until 2030 included measures to support domestic developers. This is necessary, among other things, in the light of the current geopolitical situation and sanctions from the United States and European states.

The document, according to the Kommersant newspaper, is aimed at regulating the quantum communications industry. Quantum technologies are planned to be used to protect various information systems, in particular, electronic voting platforms and interdepartmental interaction. Quantum encryption can be used to transmit confidential information: due to the fundamental laws of physics, it is impossible to imperceptibly steal data transmitted through such channels in principle. The possibility of using quantum technologies in transport and in the field of communications is being considered.

The developed concept assumes that the authorities RUSSIAN FEDERATION will limit the purchase of imported software and equipment for quantum systems: foreign technologies are proposed to be introduced into government decree No. 616, which prohibits the purchase of foreign goods to ensure security. states In addition, a unified register of quantum technologies will be formed to plan measures of state support for Russian manufacturers. At the same time, the authors of the document consider it necessary to attract foreign specialists for the development of the quantum industry: for this they can be provided with benefits corresponding to what are now in effect for employees of Russian IT organizations.

It is reported that Russian Railways is one of the organizations responsible for the implementation of the concept. Specialists from the National Quantum Laboratory, created under the auspices of Rosatom, took part in the work on the document. Experts say that in Russia there is a decline in the development of quantum technologies: in 2022, 16 applications were submitted for inventions in the relevant area against 28 in 2021.^[8]

The Government of the Russian Federation has developed the concept of regulating quantum communications until 2030

In July 2023, Prime Minister Mikhail Mishustin signed a decree approving the concept of regulating the quantum communications industry until 2030. The main goals of the document are to stimulate the development of the quantum communications market, support domestic manufacturers, and achieve a high level of information security for citizens and state organizations.

The concept emphasizes the need to form a legal mechanism governing the use of quantum communications in existing communication networks, as well as the creation of new quantum communication networks. Experimental legal regimes in the field of digital innovation can become such a mechanism. It is advisable to install them in certain areas, for example, in unmanned vehicles and logistics, the Internet of Things, portable electronics, and promising mobile networks.

The concept assumes that the technical regulation of the quantum communications industry should be based on national standards that will establish requirements for quantum communications networks.

Also, the new industry should be represented in the All-Russian Classifier of Economic Activities. This is necessary so that various industry organizations, such as manufacturers of quantum communications equipment, can receive support from the state. For the same purpose, companies working with quantum communications will receive the right to be accredited as Russian organizations operating in the field of information technology.

According to the press service of the Cabinet of Ministers on July 17, 2023, interested departments together with Russian Railways should submit proposals for the implementation of the concept to the Ministry of Digital Development within three months.

An algorithm for continuous monitoring of the characteristics of a quantum processor has been developed

In Russia, an algorithm has been developed for continuous monitoring of the characteristics of a quantum processor. The corresponding results of the study, supported by a grant from the Russian Science Foundation (RNF), were published in the journal Physical Review Applied in February 2023.

Scientists from the Russian Quantum Center (Moscow) and MISIS University (Moscow) have developed a new algorithm for monitoring the characteristics of the basic elements of a quantum processor, which allows obtaining fairly accurate estimates of their behavior based on the analysis of information obtained after the launch of user chains. The algorithm was tested both for artificially generated data obtained from a quantum emulator and for experimental data collected from a publicly available cloud quantum processor.

The main feature of the developed system compared to other benchmarking methods is that it does not borrow additional computational time from the quantum processor: all state estimates of quantum processors are made on the basis of quantum chains launched by users. Using the proposed method will significantly reduce the resources required for their benchmarking and calibration. The monitoring system maximizes the already available data from the implemented quantum algorithms without the need to run additional procedures.

{{quote 'We tested the developed system using artificially created and experimental data obtained by running circuits on a 5-qubit superconducting quantum processor, which is available through the cloud.

ITMO has proposed a protocol for generating confusing states that will help create next-generation chips

Scientists ITMO proposed a universal method for generating quantum correlations and entangled states. It allows you to dynamically influence the parameters of the system and set the desired characteristics of photons, for example, grouping phenomena or anti-grouping. The study opens up possibilities for encoding entangled states in superconducting qubits and processing quantum information in next-generation optical chips. This was announced on January 11, 2023 by representatives of ITMO.

As reported, for devices based on superconducting qubits, for example, next-generation chips or quantum computers, it is important to create entangled Bell states. These states ― the foundation for any processing of quantum information, quantum computing and the development of ultrafast processors. Modern systems allow you to create installations for generating sources of several photons, but their parameters are determined immediately during the production of the design, that is, it is impossible to control the characteristics of the system. This limits research and technical capabilities.

Scientists of the New Physics and Technology Institute ITMO have found a solution to this problem. They proposed a theoretical protocol for dynamically generating stable quantum correlations and entangled Bell states in frequency comb radiation from an array of superconducting qubits. The method is universal, takes into account the temporal evolution of qubits, and can be used to control photon correlations in dynamically modulated quantum systems.

Our protocol adds a kind of "toggle switch" to the system, with which you can switch ― modes from grouping photons (when particles are emitted in groups) to anti-grouping, when each particle emits independently. This allows you to achieve the desired system or installation parameters. We also proposed a simple, but very effective way to generate a frequency comb of the system (a simple two-level quantum system): we take two qubits, put them into the system and "shake" their levels (with a slight phase lag). As a result, we got a chess diagram of the effects of grouping and anti-grouping, protected by the symmetry of the system, and the ability to dynamically generate multiphoton entangled states with a certain accuracy, simply finding the desired law of "shaking." explained Denis Ilyin, study author, master's student of the New Physics Department of ITMO

The researchers conducted analytical calculations of correlation functions at small shaking amplitudes and calculated entropy of entropy of photon states depending on the parameters of the "shaking" system, confirmed the corresponding conclusions by numerical calculations, expanding the applicability of the method to a range of large amplitudes.

Scientists have shown that mutual correlations between signals in the waveguide can be controlled, and also proposed an effective way to control. The results of the study suggest the ability to control signal correlations during single-channel transmission of quantum optical information. This opens up additional possibilities for future protocols for processing quantum information of next-generation devices (for example, computing devices).

The authors will develop the study, their plans ― experimental confirmation of the hypothesis, as well as a change in the parameters of the system under study (scientists want to introduce mechanical degrees of freedom into it).

The work is supported by grants, RSF as well as Ministry of Education and Science RUSSIAN FEDERATION the Priority 2030 program.

Russian scientists have patented the architecture of a quantum processor based on kudits

A group of scientists from the Russian Quantum Center received a patent for the physical implementation of a quantum computer based on kudits - quantum systems that can simultaneously be in more than two states. The document applies to the territory of the Russian Federation until the end of 2040. The researchers also plan to apply for international registration soon.

Quantum computing devices use such phenomena of quantum physics as entanglement and superposition, which allows quantum bits (qubits) to be in two states - both 0 and 1 - at the same time, thereby solving problems that are inaccessible to classical computers and supercomputers. However, in physics, there are also extended versions of qubits - kudits that can take more than two states: 0, 1, 2, and others.

Research in the use of kudits for quantum computing has been conducted by a group of scientists from the Russian Quantum Center for the past few years. Obtaining a patent will allow the team in the future to confirm the importance of domestic developments at the world level and consolidate the exclusive right to the architecture of the created processor. Its feature lies in a combination of two approaches to increasing the power of a quantum computer.

The first approach involves replacing qubits with an equivalent number of kudits, the second involves using additional levels of kudits instead of individual auxiliary qubits (ancillas) to perform intermediate calculations. The patent protects the optimal method of combining approaches proposed by scientists.

In the world, only four teams are working on the development of curly quantum processors. The American Riggeti Computing uses kudits on superconductors, scientists from Peking University - on photons, Austrian startup AQT and researchers from the Russian Quantum Center - on ions. Russia In the work on the creation of a curdy quantum computer on ions, it is being implemented within the framework of the project of the Leading Research Center (FACE) with the support of the Russian venture capital company.

"Using qubits for quantum computing implies some idealization. Kudits are a more natural choice. As our research has shown, when implementing quantum algorithms, kudits significantly save the resources of quantum processors, which is especially important for the current generation of devices, "said Alexey Fedorov, co-author of the patent, head of the Quantum Information Technologies scientific group at the Russian Quantum Center.

Russian scientists have developed a method for creating quantum entanglement

On May 4, 2022, NUST MISIS reported that its scientists had developed a method for forming a connection between multi-level quantum bits, allowing for a stable exchange of information between them. The technology could form the basis for the production of commercial quantum computers. The study was published in the journal Physical Review B.

Quantum computer is a device storing that processes information within a group of quantum systems, each of which is usually two-level and is called a "quantum bit" or "(English" qubit qubit "- quantum bit). However, in addition to qubits, there are also more complex units of quantum memory, the so-called cutrites and cookwarts, consisting of three and four levels, respectively. In theory, the use of such information storage and processing units will make it possible to create more efficient and compact quantum ones, processors but creating a stable connection between them presents a number of difficulties. In 2021 the Russian , scientists demonstrated an ion quantum processor based on cookwarts.

A group of physicists led by Alexei Fedorov, a researcher at NUST MISIS and the head of the scientific group of the RCC, has developed a method that allows forming connections (the so-called quantum entanglement) between arbitrary three-level qubits. The work was supported by the program of the Research Center for Quantum Computing.

The approach proposed by Russian scientists is based on a method previously used by their colleagues from the United States to create so-called time crystals - a structure of 20 qubits, the states of which they controlled using microwave radiation. At the same time, qubits are located relative to each other in such a way that their backs constantly interact, and external action ensures the duration of this interaction. An important feature of such a system before analogues is that the force of interaction of qubits with the external field and with each other can be easily adjusted.

Russian scientists in their work have demonstrated that similar chains of interactions between quantum objects and specially arranged pulses of electromagnetic radiation can be used to form connections between pairs of arbitrary cutrites that are far from each other.

At the same time, the effectiveness of the proposed method of creating quantum entanglement between cutrites, according to scientists, can be tested using existing analog computers.

"We have developed that protocol allows you to bind individual cutrites in one-dimensional chains of similar objects. We expect that its work can be tested using existing analog quantum computers based on, for example, neutral atoms or ions. This approach of forming quantum entanglement is interesting from the point sight of creating unusual quantum phases of matter, as well as as a necessary element for quantum computing, "- explains Alexey Fedorov.

According to the authors of the work, confirmation of the effectiveness of the protocol they created will allow using such structures to create commercial quantum computers based on multi-level qubits.

Russian scientists have proposed an up-to-date approach to scaling quantum computers

On April 6, 2022, Russian Quantum Center"" reported that a group of its scientists demonstrated the possibility of scaling quantum, computers not increasing the number of quantum carriers, but information using their additional levels. The results of the experiment, supported by Russian scientific the foundation, are published in the international journal in physics, Physical Review A.

The main feature of quantum computing is the ability to solve certain classes of problems orders of magnitude faster. If the classical bit is in state 0 or 1, then the quantum bit (qubit) is able to receive both states at once: both 0 and 1. This property, along with quantum entanglement, allows quantum computing devices to increase power exponentially as the number of qubits increases.

However, the main barrier to the efficient application of the technology remains the insufficient number of qubits associated with the complexity of controlling a plurality of independent particles. So, to solve optimization problems, thousands of qubits are needed, to analyze the structure of the nitrogenase cofactor - 4 million qubits, and for breaking cryptographic algorithm RSA - about 20 million qubits.

In the course of the study, scientists proposed an optimal scheme for the implementation of one of the key operations used in almost all quantum algorithms - the Toffoli gate. However, instead of qubits, physics used a variety of multi-level quantum systems (kudits) - cutrites. Unlike qubits, cutrites can be in 3 states at the same time, which increases the performance of calculations and the quality of quantum operations. The circuit was demonstrated on a superconducting quantum computer. The results obtained will significantly speed up the introduction of quantum computing into the industrial environment.

"Implementing qubits using real physical systems involves a certain idealization - the number of levels in atoms, ions, superconducting chains and other systems is usually more than two. The idea of ​ ​ kudit quantum processors is to use additional layers of physical systems to increase the quality of implementation of quantum operations and "denser" coding of quantum information. To demonstrate the scheme, a superconducting quantum computer was chosen. In Russia, within the framework of the project of the Leading Research Center (FACE), work is underway to create a curly quantum computer based on ions, "- reported by Alexey Fedorov, author of the study, head of the scientific group "Quantum Information Technologies" at the "Russian Quantum Center."

The results of the work are published in the scientific journal Optics Express. This was announced to MISiS by TAdviser on October 21, 2021. Read more here.

Launch of ecosystem intercollegiate quantum network in Russia

On October 14, 2021, it became known that the first ecosystem intercollegiate quantum network was launched in Russia.

The project to create an open quantum network is being implemented by members of the consortium of the Competence Center of the National Technological Initiative (NTI) "Quantum Communications," created on the basis of NUST "MISIS": MTUSI, LLC "KuRait," LLC "Security Code."

The intercollegiate quantum network consists of five nodes located in the housings of NUST "MISIS" and MTUSI, it has an open architecture and scales as participants appear. Universities, scientific organizations, industrial partners, government agencies and student startups get access to the network. On the basis of the network, they can develop software applications in the field of information security using quantum keys.

The configuration of the quantum secure communication channel corresponds to that adopted in industrial networks. On the fiber between trusted nodes, a 30 kbit/s quantum key distribution (KPC) method is implemented, which allows you to connect more than 10 high-speed encryptors at the same time.

The developers have demonstrated that it is possible to remotely control a robot manipulator via an optical communication channel protected from attacks using quantum key distribution technology for October 2021. In the future, this will allow transferring, for example, design solutions and technical documentation between geographically remote production sites and concern offices around the world.

The consortium of the NTI Center plans to attract participants who can connect to the network from October 14. Together they will be able to finalize the architecture of the quantum network to a "ring," which will give other opportunities for its development. The advantage of this topology is that when the fiber breaks, the network connectivity is not lost and the data is sent over the backup channel. In addition, on the basis of the "rings" you can build a more complex urban network in architecture, when one node works for many consumers - banking and financial organizations, telecom operators, business representatives in the field of the fuel and energy complex, transport, technologies.

It is important to note that remote access to the quantum network will be free for representatives of the state, and for the corporate sector, and even for private business. We want everyone to be able to test software solutions using quantum keys. In the future, other organizations within 100 km will be able to connect optically to the network between NUST MISIS and MTUSI. The key transfer rate will depend on the quality and novelty of the fiber. As of October 2021, we are talking about about 30 kbps, "said Pavel Vorobyov, executive director of QRate.

The peculiarity of the first ecosystem quantum network lies in the implementation of an open approach and the creation of practical benefits for each participant. Thus, any developer of software solutions in the field of information transfer and storage protection will be able to use this infrastructure and debug their program code. Or create an application, for example, for the Internet of Things based on quantum keys and here demonstrate it to potential customers. As a result, customers invest in useful software, and this, as a result, will accelerate the development of the quantum communications market, - commented Yuri Kurochkin, director of the Competence Center of the NTI Quantum Communications NUST MISIS.

In 2018, the Center of NTI "Quantum Communications" was opened on the basis of the university, which was headed by a Ph.D. Yu. V. Kurochkin. The center is engaged in scientific research, training specialists in the field of quantum communications. In 2021, scientists of the Center, together with colleagues from MTUSI, KuWright and Security Code, launched the first open access quantum network in Russia, which will become part of a project to create software solutions for protecting information, - said the rector of NUST MISIS Alevtina Chernikova.

It is very important for us, as an industry university, that Russian scientists get the opportunity to conduct their research in the field of quantum communications on a real optical network. For telecom operators and manufacturers of telecommunications equipment with elements of quantum technologies, it becomes possible to test their equipment on a real network, and not only in laboratory conditions, - said the rector of MTUSI Sergey Erokhin.

Only the synergy of information security specialists, scientists and attention from the state will be able to realize the potential of quantum communications. We are glad to take the first step in this direction by implementing the project of an intercollegiate communication channel with quantum encryption, "said Andrey Golov, General Director of Security Code LLC.

The new head of IBM doubted the possibility of Russia to create a quantum computer

On February 20, Arvind Krishna, who will head IBM from April 6, expressed doubt about Russia's ability to create its own quantum computer. According to him, IBM is a decade ahead of everyone in the world in terms of the development of such technologies.

I have great respect for Russia. When I was in graduate school, I read a lot of textbooks and materials that were written by Russian mathematicians and physicists. But how much can it be used? Whether a quantum computer can be created at an affordable price is a big question, "he said in an interview with RIA Novosti.

The future head of IBM recalled that Russia announced plans to invest several billion dollars in the creation of quantum computers. The United States, Britain and Canada did the same, China has a $10 billion program.

Each country has announced its own quantum computer programs... I think this does not mean that they have the opportunity to do this, - said a top manager at IBM.

In his opinion, for significant progress in the field of quantum technologies, innovations in the field of modern experimental materials science and corresponding scientific competencies are needed.

Among IBM's main competitors in the development of quantum technologies, Krishna  included Google, Honeywell and Chinese companies that have already tested quantum communications.

At the same time, he did not rule out the possibility of IBM's cooperation with Russia on quantum technologies and made a reservation that the creation of partnerships depends on the geopolitical situation.

I think anything is possible, but I stay away from geopolitics. Science, unfortunately, depends on geopolitics and export controls. As a corporation, we want to work with anyone if technology is used for good, not the military, "he said.

RIA Novosti notes that by February 2020, IBM created quantum systems with 53 qubits, and in the assets of Russian scientists - development on two qubits.^[17]

The budget for the development of quantum technologies in Russia was estimated at 44 billion rubles

On May 23, 2019, it became known about the plan for the development of quantum technologies, which was developed by the Russian Quantum Center (RCC) and NUST MISIS together with experts. According to this plan, by 2024 Russia should reduce the lag in the quantum domain, and this will require 43.85 billion rubles.

Almost half of this amount (21.41 billion rubles) is needed for grants for projects for the development and use of technologies, 6.8 billion rubles for implementation projects, 5.4 billion rubles for supporting research centers, 4.42 billion rubles for supporting leading companies, according to the presentation of the plan, which was at the disposal of the newspaper "Kommersant."

It states that by 2024 Russia will become a significant player in the quantum technology market. So, in some areas it will be possible not only to reduce the backlog, but also to "reach the world level," for example, taking 8% of the global quantum communications market.

Experts propose to create a separate structure for the development of technologies. Its founders can be, " ANO "Digital Economy"," Russian venture capital firmRostec"," "," "," RosatomRostelecom and Gazprombank" Sberbank Skolkovo." Among the possible participants in the projects as performers and customers are Yandex Mail.ru Group cellular operators.

Rostelecom will engage in quantum communications, sees commercial potential in this technology and has already begun "a large-scale series of testing of solutions from Russian vendors providing quantum encryption," the company told Kommersant and noted that the start of commercial use of the technology depends on the certification of equipment and solutions, this is a slow process.

Infotex told the publication that they are ready to participate in the development and pilot implementation of quantum key distribution systems and cryptographic information protection tools based on them.^[18]

Roadmap for the development of quantum information processing technologies approved

In March 2019, the Advanced Research Fund hosted a meeting of the interdepartmental working group on quantum information processing technologies under the Council on the priority direction of the Strategy for Scientific and Technological Development of the Russian Federation "Transition to advanced digital, intelligent production technologies, robotic systems, new materials and methods of design, creation of systems for processing large amounts of data, machine learning and artificial intelligence."

The meeting was attended by representatives of federal executive bodies, state corporations, and scientific organizations. The meeting participants approved the draft roadmap for the development of quantum information processing technologies in the Russian Federation. The document was developed with the aim of obtaining in the medium and long term practically significant scientific and technical results of the world and leading level in the fields of quantum computing, quantum modeling, quantum communications and quantum cryptography.

According to Maxim Vakshtein, head of information research at the Advanced Research Fund, the mutual linking of the planned and already performed work within the framework of a single roadmap will ensure an increase in the efficiency of the research carried out by coordinating the work carried out by individual domestic scientific teams, consolidating the resources of the main state customers and standardizing the requirements for quantum information processing technologies. Also, the roadmap will contribute to the formation of a favorable environment for the development of the professional community and systemic training of personnel.

Among the key projects being implemented in Russia today in the field of quantum information processing technologies is a joint project of the Advanced Research Fund and Lomonosov Moscow State University to create demonstrators of 50-qubit quantum computers based on neutral atoms and integrated optical circuits. The project started in October 2018, at the moment, on the basis of the laboratory of quantum optical technologies of the Physics Department of Moscow State University, the first control experiment was successfully carried out to create traps for arrays of neutral cold atoms. The project to create a quantum computer is designed for a period until 2021^[19] has been^[20].

MSU's successful experiment to create traps for arrays of neutral cold atoms

On January 18, 2019, it became known that the Lomonosov Moscow State University successfully carried out an experiment to create traps for arrays of neutral cold atoms. The experiment is part of the work to create a 50-qubit quantum computer.

Earlier, a project was launched at Moscow State University to create demonstrators for 50-qubit quantum computers. Neutral atoms and integrated optical circuits will serve as the basis for them. The project is designed for a period until 2021.

A control experiment on the creation of traps for arrays of neutral cold atoms was carried out on the basis of the laboratory of quantum optical technologies of the Physics Department of Moscow State University. In a future quantum computer, atoms in a state of chaotic motion will be fixed in these traps. In quantum computers, such atoms are carriers of information.

As you know, quantum computers, unlike classical computers, operate not with bits, but with qubits, which can be not only in states "1" and "0," but also their superposition. When developing quantum computing devices, scientists try to introduce qubits into a state of quantum entanglement. The essence of the phenomenon is that changing one qubit always affects the state of its associated neighbors. Thanks to this, quantum computers are potentially able to demonstrate high performance in computing.

An important milestone for quantum technologies is the achievement of the so-called quantum supremacy - the ability to produce calculations faster than classical systems. The main problem of quantum technologies at the current stage of development is the emergence in the process of operation of a large number of errors in need of correction^[21] in the^[22].

Agreement on the creation of a 50-qubit quantum computer

On February 15, 2018, Vnesheconombank, VEB-Innovations, the Advanced Research Fund, Lomonosov Moscow State University and ANO Digital Economy signed an agreement on the implementation of a comprehensive scientific and technical project to create in Russia a multi-bit (at least fifty qubits) optical quantum simulator based on photon chips and neutral atoms.

The main areas of cooperation under the agreement will be to ensure resource support for the implementation of the project, coordinate scientific and technical tasks and promote the implementation of the results created. In addition, within the framework of the project, the development of the necessary research and technological infrastructure will be ensured, as well as consultations, working meetings and other events for setting and fulfilling applied tasks in the field of quantum technologies.

According to modern ideas, the creation of a 50 qubit quantum computer will achieve quantum superiority: this means that such a computer will demonstrate computing power that cannot be achieved using the most modern computers operating with bits.

Experiments with quantum computers are already being carried out, but their computational abilities are still inferior to the capabilities of our usual computer technology, "said Andrei Grigoriev, General Director of the Advanced Research Fund. - To achieve breakthrough results, it is necessary to develop all existing technologies for the physical implementation of quantum computers. There are several scientific groups in Russia that have a strong scientific and technical reserve and experience in implementing practical projects in the field of quantum technologies. Combining their efforts with the capabilities of development institutions and state funds will make it possible to obtain applied results in the near future.

According to Kirill Bulatov, CEO of VEB Innovations, the agreement will create scientific collaborations and formats of interaction between Russian organizations working in the field of quantum technologies.

The signed agreement to create a quantum computer will be the challenge that will give impetus to unite the strongest participants in the field of quantum technologies. The documented foundations of cooperation will allow us to concentrate the best minds and forces of various scientific institutions and companies for Russia's technological breakthrough into the digital economy, "said Evgeny Kovnir, General Director of the Digital Economy ANO.

Quantum phone ViPNet presented in Russia

On December 13, 2017, InfoTeCS announced the introduction of the ViPNet Quantum Phone, a system that demonstrates the integration of quantum key distribution equipment.

The product was developed in the laboratory of quantum optical technologies of the Physics Department of Moscow State University, and VPN ViPNet (using the example of two products - ViPNet Client and ViPNet Connector). The ViPNet quantum phone allows you to connect workstations to installed ViPNet software and encrypt traffic between them using quantum key distribution. Quantum key distribution allows you to ensure a high level of security when transmitting data over untrusted (public) communication channels, helps to eliminate the threat of calculating security keys on quantum computers.

Scientists from Russia and the United States have created a 51-qubit quantum computer

In July 2017, it became known that a group of scientists from Harvard University and the Massachusetts Institute of Technology, led by Mikhail Lukin, a professor of physics from Harvard and co-founder of the Russian Quantum Center, created and tested a programmable quantum computer based on 51 qubits, thus becoming the leader among participants in the "quantum race."

According to Mikhail Lukin, he and his colleagues used qubits based on "cold atoms" that were held by optical "tweezers" - specially organized laser beams. Most modern quantum computers rely on the use of superconducting qubits based on Josephson contacts.

Lukin and his colleagues managed to solve with the help of their quantum computer the problem of modeling the behavior of quantum systems from many particles, which was practically unsolvable with the help of classical computers. Moreover, as a result, they were able to predict several previously unknown effects, which were then tested using conventional computers. As a result, scientists managed to find a way to approximate calculations that helped to get a similar result on a classical computer.

In the near future, scientists intend to continue experiments with a quantum computer, perhaps they will try to use this system to test quantum optimization algorithms that allow them to surpass existing computers.

"Quantum phone" tested in Kazan

Employees of the Kazan Aviation Institute (KAI) and St. Petersburg National Research University of Information Technologies, Mechanics and Optics (ITMO) presented a four-node quantum network in Kazan at the beginning of 2017 and tested it, in particular, using it as a phone that cannot be listened to. Kazan ^[23]

Such networks began to appear in Russia in 2014: the first projects were carried out by the capital's universities. Pilot tests of the Kazan network were carried out in August 2016. Now scientists have finalized the network, and it is fully functional. Two nodes are located in KAI, two more - on the banks of the Kazanka River. As part of the tests, files and various commands were transmitted over the network channels, then the network was used as a telephone for testing audio communication.

According to the director of the Kazan Quantum Center Sergei Moiseev, KAI scientists have been studying quantum memory for 15 years, and their colleagues from ITMO are interested in their development to create a network of communications at long distances. Now scientists are planning to improve the speed and range of quantum channels, as well as look for new practical applications of the technology.

In the Moscow region, quantum communication was experienced between two cities

On October 5, 2016, the press service of the Advanced Research Fund announced tests of a quantum communication system between two cities of the Moscow Region. Project participants: Moscow State University, Rostelecom and the Advanced Research Fund.

Three-week tests of the automatic system of quantum distribution of cryptographic keys based on standard communication lines of PJSC ROSTELECOM were carried out in the Moscow region: messages encrypted through quantum technologies were exchanged between cities. Quantum communication worked between Noginsk and Pavlovsky Posad on a 32 km long fiber optic line.

The main purpose of the tests is to demonstrate the capabilities of the long-term and stable operation of the quantum distribution system of cryptographic keys based on the standard infrastructure. Tests showed the stability of the system on the fiber optic lines of PJSC Rostelecom between the cities of the Moscow region, Noginsk and Pavlovsky Posad, in automatic mode.

The tests carried out are of fundamental importance for the development of the entire industry of quantum technologies. During the tests, the "three whales" of the modern quantum connection were demonstrated. First, symmetric cryptographic keys were distributed in accordance with GOST. Key distribution took place in quantum network mode, when identical keys were generated from pairs of subscribers at their request. Secondly, quantum communication was carried out between two specific settlements - cities of the Moscow region. Thirdly, the system operates in a fully automatic mode, without the participation of the operator. Sergei Kulik, Head of the Laboratory of Quantum Optical Technologies, Moscow State University, Professor, Member of the Test Commission

The operator's participation was required at the first start of the system and setting its main parameters, depending, for example, on the distance between subscriber stations. All values of the system operation parameters are tested and supported automatically: the system adjusts them depending on fluctuations in the indicators of the fiber optic line. During the tests, a client-server version of the system was used, which allows it to achieve long-term and stable operation and minimize the cost of the client node.

The keys were distributed between the central server and several client nodes: successively received at various nodes, the keys were specially synchronized, which allowed subscribers to directly exchange messages encrypted in accordance with the Russian national standard. The system provides cryptographic properties that meet the requirements of GOST 28147-89.

The system, which includes a server station with the ability to switch between 32 client nodes, uses the original domestic data transfer protocol. Its cryptographic resistance allows you to generate keys suitable for use in modern and promising hardware and software tools for cryptographic protection of limited access information.

Demonstration of the long-term operation of the network version of the quantum key distribution system, operating on the infrastructure of standard fiber-optic communication lines and meeting all the requirements for cryptographic resistance, shows that the conditions for the introduction of this technology have been created in Russia.

Pilot quantum data network in Tatarstan

On August 8, 2016, scientists in Tatarstan launched a pilot project for a multi-node quantum data transmission network. This is the first project in Russia. According to the creators, a network with increased data protection will unite the cities of the republic, primarily public sector enterprises, financial and scientific structures.

The authors of the project are scientists from the quantum center of the Kazan National Research Technical University (KNITU-KAI) and the St. Petersburg National Research University of Information Technologies, Mechanics and Optics (ITMO)^[24]

The platform for the network was the equipment of the telecom operator PJSC Tattelecom. Quantum cryptography differs from conventional data protection by using physical methods instead of mathematical ones. The hacking attempt changes the parameters of electrons or photons, which makes it possible to detect unauthorized access.

The quantum network will combine four nodes 30-40 km apart. The first section of the network was launched in Kazan, it connected the two buildings of the university.

The pilot segment achieved a rate of generation of sieved quantum sequences of 117 kbit/s on a 2.5 km line - an order of magnitude faster than in European network projects in the field of quantum communication. Experiments have successfully demonstrated the transmission of quantum bits in an optical channel with losses of 20 dB, which is equivalent to a distance of 100 km.

Previously, only quantum communication lines operating on the point-to-point principle were created in Russia. For example, university buildings in St. Petersburg and bank offices in Moscow were connected with a fiber optic cable. In the case of bank offices, the total line length is 30.6 km, and the key transfer error rate did not exceed 5%.

We want to build a network between Kazan and Naberezhnye Chelny. Now we are working on the equipment itself, for example, to speed up data transmission. The distance for quantum transmission is about 100 km. And then the new nodes "lengthen" the network. Sergey Moiseev, Director of the Kazan Quantum Center KNITU-KAI

The launch of pilot sites connecting universities will lead to explosive growth of technologies and the formation of new markets, on the basis of which the domestic communication infrastructure of the new generation will grow.

Russia has found a way to "compress" several elements of a quantum computer into one

Physicists from MIPT and the Russian Quantum Center have developed a method that will simplify the task of creating a universal quantum computer - they have found a way to use multi-level quantum systems (kudits) for this, each of which is able to work as several "ordinary" quantum elements, qubits. Professor Vladimir Manko, Scientific Director of the Laboratory of Quantum Information MIPT and employee of the FIAN, employee of the Russian Quantum Center Alexey Fedorov and his colleague Evgeny Kiktenko published the results of their research on multi-level quantum systems in a series of articles in the journals Physical Review A, Physics Letters A, as well as Quantum Measurements and Quantum ^[25]

"In our work, we have shown that correlations similar to those used for quantum information technology in composite quantum systems also take place in non-composite systems, which we assume sometimes turn out to be easier to work with. In particular, in the latest work, we proposed a way to use the entanglement between the internal degrees of freedom of a single eight-level system to implement the quantum teleportation protocol, previously experimentally implemented for a system of three two-level systems, "says Vladimir Manko.

Quantum computers, which promise to lead to a revolution in computer technology in the future, are supposed to be built from elementary computational elements, quantum bits - qubits. While elements of classical computers (bits) can only be in two states (logical zero, and logical one), qubits are created on the basis of quantum objects, which can be in a coherent superposition of two states, which means they can encode intermediate states between logical zero and one.

When measuring a qubit, we get either zero or one with a certain probability (determined by the laws of quantum mechanics). The operation of a quantum computer is based on the fact that the initial condition of some problem is written in the initial state of the qubit system, then these qubits enter into a special interaction (determined by a specific problem), and finally, the user reads the answer to the problem, measuring the final states of quantum bits.

Quantum computers will be able to solve some problems that are now absolutely inaccessible even to the most powerful classical supercomputers. For example, to "hack" the RSA cryptographic algorithm, based on the search for decomposition into prime factors of large numbers, an ordinary computer will take a time comparable to the lifetime of the Universe, and a quantum computer can solve it in minutes. However, there is a serious obstacle in the way of quantum revolution - the instability of quantum states.

Quantum objects that are used to create qubits - ions, electrons, Josephson contacts - can retain a certain quantum state for a very short time. But for calculations, it is necessary that the qubits not only preserve the state, but also interact with each other. Physicists around the world are trying to extend the lifespan of qubits.

Previously, superconducting qubits "survived" nanoseconds, and now they manage to keep them from decoherence for milliseconds - already close to the time that is necessary for calculations. But in the case of a system of tens and hundreds of qubits, the task becomes fundamentally more difficult. Manko, Fedorov and Kiktenko began to solve the problem "from the other end" - not to try to maintain the stability of a large qubit system, but to reduce the size of the system necessary for computing. They explore the possibilities of using for calculations not qubits, but kudits - quantum objects in which the number of possible states (levels) is greater than two (their number is denoted by the letter D). There are three-state cutrits, four-state cuckoos, etc. Algorithms in which the use of kudits can demonstrate advantages over the use of qubits are now being actively studied.

"A kudit with three to four levels can already work as a system of two" ordinary "qubits, and eight levels is enough to simulate a three-qubit system. At first, we perceived this equivalence as mathematical, which allows us to obtain new entropy relations. For example, we obtained the amount of mutual information (correlation measures) between virtual qubits allocated in the state space of a single four-level system, "says Fedorov.

He and his colleagues showed that on a single five-level kudit implemented using an artificial atom, full-fledged quantum computing can already be carried out, in particular, the Deutsch algorithm can be run. This algorithm is designed to check the values ​ ​ of a large number of binary variables. It can be called the "defective coin search algorithm": imagine you have plenty of coins, some of them defective - they have the image on the obverse and reverse matching. To find coins like this in a "classic way," you need to look at each side. Deutsch's algorithm assumes that you "confuse" the obverse and reverse of the coin, and after that you can only see the defective coin once by looking at it.

The very idea of ​ ​ using multi-level systems to emulate multi-cube processors was proposed earlier in the works of Russian physicists from the Kazan Institute of Physics and Technology. So, for example, to implement the two-cube Deutsch algorithm, it was proposed to use the 3/2 nuclear spin, which has four different states. However, the experimental progress of recent years in creating kudits on superconducting circuits demonstrates a number of their advantages. In superconducting circuits, however, five levels are already required: the last level performs an auxiliary role to implement the full set of all possible quantum operations.

"We get a significant gain, since multilevel kudits in certain physical implementations are easier to control than a system of the corresponding number of qubits, which means we are one step closer to creating a full-fledged quantum computer. Multilevel elements provide advantages in other quantum technologies, for example, in quantum cryptography, "says Fedorov.

2013: Qubit condition measured in Russia

In June 2013, it became known that specialists from the university laboratory MISIS, in cooperation with the Russian Quantum Center (RCC), were the first in Russia to measure the state of the qubit. A team of researchers led by a member of the scientific council of the RCC, Professor Alexei Ustinov, conducted an experiment to measure the state of a superconducting qubit. Scientists managed to observe the periodically changing qubit signal, as well as measure its resonant frequency.

Superconducting qubits are rings of a superconductor with a diameter of several microns. In some places of the rings there are nanometer-sized breaks - they are called Josephson transitions. The superconducting rings are cooled to a very low temperature with a mixture of liquid helium-3 and helium-4 and placed in an ultra-fine-tuned weak magnetic field. As a result, they acquire quantum properties similar to those of atomic spins.

Russian scientists were able to create an experimental chip with 7 superconducting qubits placed in microwave resonators. Interaction with the superconducting qubit affects the microwave spectrum, which makes it possible to judge the current state of the qubit without disturbing this state, that is, to bypass the problem of decoherence. The most stable of the 7 qubits was measured in MISiS.

In the current successful experiment, RCC and MISiS specialists demonstrated the ability to read the state of an individual superconducting qubit in a symmetrical superposition of 0 and 1. In the near future, the next stage: bringing the superconducting qubit to an arbitrarily selected desired state. This will require a new pulse technique, which will be installed in the new laboratory of the RCC.
