Original title: A new breakthrough in key equipment for superconducting quantum computing in China.
Reporter Xu Jing) Recently, Anhui Provincial Quantum Information Engineering Technology Research Center and Science and Technology Shield Quantum Technology Co., Ltd. jointly released the news that the domestic dilution refrigerator EZ-Q Fridge completed the performance test after being delivered to the customer, and the results showed that the actual operation index of the equipment reached the international mainstream level of similar products, becoming the first domestic dilution refrigerator for superconducting quantum computers that can be commercially produced and mass-produced.
The dilution refrigerator is a key core equipment for building superconducting quantum computers, which can provide an ultra-low temperature environment close to absolute zero for superconducting quantum computing chips, and its market has been occupied by international manufacturers such as Finland, the United Kingdom, and the United States. In order to solve this "stuck neck" problem, a joint team composed of the University of Science and Technology of China and the University of Science and Technology of China Quantum, the Institute of Physics of the Chinese Academy of Sciences, China Electronics Technology, and China Shipbuilding Industry are actively tackling key problems. However, at present, domestic dilution refrigerators that can be mass-produced and put into use are still scarce, and most of them are still in the laboratory stage.
In the second half of 2023, Keda Shield Quantum delivered domestic dilution refrigerator products to 2 scientific research units, which have been tested by customers for many months, and the equipment has been running continuously and stably for a long time, reaching the international advanced level.
