China has made a significant leap in quantum computing with the unveiling of the Tianyan-504, a record-breaking quantum computer.

China has made a significant leap in quantum computing with the unveiling of the Tianyan-504, a superconducting quantum computer featuring the 504-qubit Xiaohong chip, setting a new milestone.The Tianyan-504 quantum computer was developed through collaboration between the China Telecom Quantum Group , the Center for Excellence in Quantum Information and Quantum Physics under the Chinese Academy of Sciences, and QuantumCTek, a quantum technology company based in Anhui Province.

Furthermore, China has progressed in quantum computing with the development of a 504-qubit superconducting chip, called Xiaohong, delivered to QuantumCTek. This marks a domestic record for qubit count in a superconducting quantum chip and will support testing of QuantumCTek’s kilo-qubit measurement and control system.

The China Telecom Quantum Group will also partner with QuantumCTek to develop a quantum computer using the new Xiaohong chip. This collaboration will provide global users with access to the China Telecom Quantum Group’s quantum computing cloud platform, enabling researchers from various fields to efficiently work on practical problems and algorithms.
