CTOnews.com news on January 3, according to the official news of China Electric Technology, recently, 16 China Electric Power Institute (Hefei Cryogenic Electronics Research Institute) independently developed a liquid helium dilution refrigeration engineering prototype product that broke through the limit of 10mKelvin (absolute zero above 0.01C), and the continuous cycle working temperature reached 9.3mkel. it indicates that the localization and engineering application of dilution refrigerator products in the field of cryogenic refrigeration have entered a new stage.

CTOnews.com learned that absolute zero is the lowest temperature in thermodynamics, that is, 0 Kelvin (0K), about minus 273.15 degrees Celsius, which is the temperature of matter when the kinetic energy of particles is as low as the lowest point of quantum mechanics. The German team achieved only 38 1/1000000000000 degrees higher than absolute zero in 2021, but it can only be infinitely close to but cannot be achieved.

According to reports, the dilution refrigerator is a kind of high-end scientific research equipment which can provide near absolute zero environment, mainly provides the necessary extremely low temperature environment for superconducting quantum chips, and is the core equipment of superconducting quantum computers. 16 aim at the engineering application requirements of dilution refrigerator, overcome many key technologies such as superfluid helium suppression, micro-flow control and extremely low temperature heat transfer, and realize the engineering application of the first domestic dilution refrigerator.

China Electric said that in the future, 16 institutes will continue to develop pedigree products of diluted refrigerators, continuously enhance the competitiveness of key core technologies of extremely low temperature refrigeration equipment, and provide strong support for the development of superconducting quantum computing in China.
