Dilution refrigerators, a key component in superconducting quantum computers, can provide an environment with ultra-low temperatures, close to absolute zero. Absolute zero is the lowest temperature theoretically achievable, equivalent to -273.15 degrees Celsius. Beyond quantum computing, dilution refrigerators are widely used in advanced technological fields such as condensed matter physics, materials science , and deep space exploration.

The newly manufactured refrigerator can reach a temperature of 12 millikelvin (-273,138 degrees Celsius), cool in under 40 hours, and restore to its original temperature within 24 hours, meeting the requirements for superconducting quantum computing, according to Zhang Junfeng, a researcher at the Anhui Center for Quantum Computing Engineering Research.

Origin Quantum, a quantum computing technology company, has independently developed a new diluted refrigerator prototype. This is China's first quantum computing company, producing superconducting quantum computers in 2021, making China the third country in the world capable of supplying complete quantum computers, after the United States and Canada.

China has recently made significant strides in the development of quantum computers. According to research published on October 10 in the journal Physical Review Letters , the new JiuZhang 3 quantum computer prototype can process ultra-complex problems in a fraction of a millionth of a second.
