2024: Computer Development

At the end of April 2024, the Center for Innovative Research on Quantum Information and Quantum Physics of the Chinese Academy of Sciences (CAS) announced the development of a 504-qubit chip. A product called Xiaohong will become the basis of the most powerful quantum computer in China, which is being created by China Telecom Quantum Group and QuantumCTek.

The Xiaohong chip is capable of performing kilocube measurements. According to the project participants, the solution can compete with advanced international developments in the field of quantum computers. Access to the new computing system is planned to be provided through a specialized cloud platform developed by China Telecom Quantum Group. Moreover, not only Chinese researchers and organizations, but also foreign clients will be able to use the quantum computer.

The platform will allow users from various fields to effectively conduct research on problems and algorithms of practical importance, as well as accelerate the introduction of quantum computing in real-world scenarios, says Wang Zhen, Deputy CEO of China Telecom Quantum Group.

The Jiuzhang 2.0 photonic quantum system and the 66-qubit Zuchongzhi 2.1 programmable superconducting quantum complex, developed by Chinese specialists in 2021, provided the PRC with global leadership in achieving quantum superiority through two main technological approaches. One of them is a quantum photon processor, that is, a device that manipulates light for calculation. The second approach is to use superconducting quantum calculations: qubits in this case are created from superconducting electrical circuits that operate at ultra-low temperatures.^[1]
