2022: Demonstration of the node of the domestic quantum network

NUST "MISIS" conducted a demonstration of the work of the node of the domestic quantum network, developed by scientists of the Center for NTI "Quantum Communications." The node shown will become the basis for creating demonstration quantum computers and prototyping quantum Internet devices. On June 9, 2022, TAdviser was reported to NUST MISIS.

The presented node of the quantum network is used for demonstration research work and in the field of quantum communications photonics and on the basis of universities, R&D centers and scientific and production associations.

The complex consists of two units connected by a fiber-optic communication line and implements the so-called two-pass system, in which the receiver generates sequences of laser pulses and sends them to the transmitter. It turns out a distributed random number generator, representatives of NUST MISIS explained.

According to them, a distinctive feature of this hardware and software complex is the flexibility of the configuration, which distinguishes it from its analogues. Modularity allows you to modify optical circuits, vary electronic components, explore promising protocols, and develop interfaces for integrating quantum communications into other information systems.

According to the developers, in the future, this node of the quantum network will become the basis for the creation of a generation of demonstration quantum computers for solving educational and scientific problems based on optics. And it will also be used to prototype quantum internet devices: the next generation of quantum technologies that will allow the use and connection of remote quantum computers into a common network. This is one of the key areas of work of scientists at NUST MISIS in the framework of the Priority-2030 program.

In fact, other computing devices - the prototype of the quantum Internet - and sensor systems for the "quantum Internet of Things" will be able to connect to the presented node in the future. In particular, the laboratory "Superconducting metamaterials" NUST "MISIS" is working in this direction, in which prototypes of quantum processors and microwave interfaces are created to connect them to a quantum network, added to the university.
