Origin Quantum has launched a dilution refrigerator, a crucial device in superconducting quantum computers, capable of achieving temperatures close to absolute zero.
China has made a breakthrough in cooling capabilities of quantum systems with the independent development of a dilution refrigerator by a company in Hefei, Anhui Province, which was reported by CGTN on October 18.

The dilution refrigerator, one of the key devices in superconducting quantum computers, provides an environment with ultra-low temperatures, nearing absolute zero. Absolute zero is the lowest theoretical temperature achievable, equivalent to -273.15 degrees Celsius. Beyond the realm of quantum computing, dilution refrigerators are also widely used in advanced technology 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), with a cooling time of less than 40 hours and the capability to return to its original temperature within 24 hours, meeting the requirements for superconducting quantum computing, according to Zhang Junfeng, a researcher at the Anhui Quantum Computing Engineering Research Center.
Origin Quantum has independently developed the new dilution refrigerator model. This is China’s first quantum computing company, which produced a superconducting quantum computer in 2021, making China the third country in the world capable of providing a complete quantum computer, following the United States and Canada.
Recently, China has achieved significant milestones in quantum computing development. According to a study published on October 10 in the journal Physical Review Letters, the new quantum computer prototype JiuZhang 3 can solve extremely complex problems within a millionth of a second.
