China is building a 504-qubit quantum computer with cloud access

The creators of the most powerful quantum computer in China decided to give cloud access to it to the whole world

Chinese leaders in the field of quantum computing China Telecom Quantum Group and QuantumCTek are building a quantum computer with a capacity of 504 qubits, the Chinese state news agency Xinhua reported.

A superconductor chip for it has already been created at the Center for Innovative Research of Quantum Information and Quantum Physics of the Chinese Academy of Sciences. It has become the most powerful in the Middle Kingdom and should, according to the developers, “compete with advanced international platforms” in this area, such as IBM.

The device, called Xiaohong 2.0, runs on 113 photons under the control of the 66-qubit programmable superconducting quantum computing system Zuchongzhi 2.1. It is expected to provide cloud access to users from all over the world.

“The chip will allow users from various fields to conduct research on problems and algorithms of practical importance, as well as accelerate the implementation of quantum computing in practice,” explained Deputy General Director of China Telecom Quantum Group Wang Zheng.
