East China's Anhui Quantum Computing Engineering Research Center announced on Oct 15 that the domestic dilution chiller, a crucial component of quantum computers, has successfully been developed in China.
This marks the first time a Chinese research and development team has overcome the challenges of achieving low-temperature refrigeration for quantum computers.
The dilution chiller plays a vital role in creating an operating environment close to absolute zero for superconducting quantum computers.
The chiller can also be widely used in other cutting-edge technology fields such as condensed matter physics, materials science, and deep space exploration.
Overcoming the technological barriers in this field is understood to be a significant advancement for Chinese scientific research.
According to Zhang Junfeng, an official from the research center, the newly developed dilution chiller can provide an extremely low-temperature environment of less than 12mK and has a cooling capacity of no less than 400μW@100mK. Its cooling time of 40 hours and warming time of 24 hours are in accordance with the international standards of mainstream products.
The price of international dilution chillers ranges from 4 million to 6 million yuan ($547,297.24-821,013.56). The successful localization of this key component will not only accelerate China's self-reliance and self-improvement in the field of quantum computing but also strengthen its position as a dominant player in the global quantum computing industry.
