In a groundbreaking development, the Anhui Quantum Computing Engineering Research Center in Hefei City, Anhui Province, Chinese mainland, has successfully produced the Origin SL1000 dilution refrigerator, reported Science and Technology Daily on Tuesday.
Developed by Origin Quantum Computing Technology (Hefei) Co., Ltd, the Origin SL1000 positions the Chinese mainland at the forefront of dilution refrigeration technology, marking a significant leap in the global quantum computing landscape.
Dilution refrigerators, often dubbed \"quantum computing air conditioners,\" are essential for superconducting quantum computers, maintaining ultra-low temperatures near absolute zero for the operation of quantum chips.
The latest Origin SL1000 model offers substantial improvements over its predecessor, the SL400. While the SL400 accommodates 336 specialized high-frequency coaxial cables, the SL1000 can house up to 840 cables, meeting the stringent requirements for operational environments supporting over 100-bit superconducting quantum chips.
\"The Origin SL400 delivers 400 microwatts of cooling capacity at an ultra-low temperature of -273.05°C. In contrast, the Origin SL1000 escalates this capacity to 1,000 microwatts under identical conditions,\" explained Zhang Junfeng, a representative from the Anhui Provincial Quantum Computing Engineering Research Center. He likened the upgrade from the SL400 to the SL1000 to an air conditioner's transition from 1.5 to 3 horsepower, highlighting the significant performance enhancement.
