China has developed its largest quantum computing chip to date, a 504-qubit chip named “Xiaohong,” designed to enhance the performance of quantum computers globally. Developed by scientists at the Center for Excellence in Quantum Information and Quantum Physics, part of the Chinese Academy of Sciences, Xiaohong aims to scale up quantum computers by improving qubit management and interaction systems. China Telecom Quantum Group plans to integrate Xiaohong into a new quantum computer, which will be accessible via a quantum computing cloud platform, facilitating research and application acceleration in quantum computing across various fields globally.
