我国首款千比特超导量子计算测控系统正式交付使用

Core Viewpoint - The first superconducting quantum computing measurement and control system designed for a thousand-bit scale, ez-Q Engine 2.0, has been officially delivered for use in China, marking a significant advancement in quantum computing technology [1][2]. Group 1: Product Development - The ez-Q Engine 2.0 was developed by Keda Guo Shield Quantum Technology Co., Ltd., a subsidiary of China Telecom Quantum Group, in collaboration with other units, providing over 5,000 bits of measurement and control services [1]. - The system supports up to 128 data bits and 256 coupling bits in a single chassis, allowing for the control of a thousand-bit quantum computer with just eight units, significantly reducing costs compared to foreign products [1][2]. Group 2: Technological Advancements - The new generation device has improved integration by approximately 10 times, with core components designed domestically, addressing challenges such as RF direct sampling output and large-scale clock synchronization [2]. - Enhanced measurement and control precision has been achieved, resulting in lower noise and stronger consistency in performance metrics [2]. Group 3: Application and Impact - The ez-Q Engine 1.0 was previously utilized in the "Zuchongzhi No. 2" quantum computer, and the new ez-Q Engine 2.0 is now involved in the research of the "Zuchongzhi No. 3" quantum computer, contributing to major scientific projects [2]. - The system has been delivered to nine research and industrial units, including the University of Science and Technology of China and China Telecom Quantum Group, and has been validated for stability and precision on the "Tianyan 504," the most bit-dense superconducting quantum computer in China [2].
