Kong Weicheng, a researcher at Origin Quantum, told mainland media that quantum processors or chips must operate at extremely low temperatures, close to absolute zero (-269 degrees Celsius or -452 degrees Fahrenheit), so the module must first It can block heat.
In addition, it was also necessary to provide a fast and stable channel between the quantum computer’s “brain” and external devices to accurately transmit signals and quantum information.
Until now, the major obstacle to module independence has been Domestic production procures high-frequency coaxial cable specifically for ultra-low temperatures, which is one of its key components.
Anhui Newspaper reported on Thursday that the cables previously had to be imported from Japan and were expensive.
The newly developed module can provide a microwave signal transmission channel for quantum chips with more than 100 bits, and can achieve stable signal transmission across the temperature range in cryogenic environments, Kong said.
The module’s success allowed quantum chips to “deliver more powerful computational power,” which helped quantum computers operate more efficiently, he said.

as technology war will intensify, technical containment in Western countries will be strengthened, and the pace of infection will accelerate. reduce dependence It is extremely important for China’s quantum technology to influence other countries and achieve independence.
US Department of Commerce Updated export control list The report, released on May 9, named 22 of China’s leading companies in quantum research and industrialization out of 37 Chinese companies covered.
Origin Quantum, the backbone of China’s quantum computing research and its industrial applications, was also included in the sanctions list.
Origin Quantum was founded in 2017 by quantum physicists Guo Guoping Guo Guangcan from the University of Science and Technology of China in southeastern Anhui province. In creating this module, the company collaborated with the 40th Research Institute of China Electronic Technology Group, a research institute also based in Anhui province.
Origin Quantum powers China’s independently developed quantum computer Origin Wukong. Published to users worldwide in January. The machine has now completed more than 183,000 quantum computing tasks, the state-run China News Agency reported on Wednesday.
Origin Wukong, named after the Monkey King in Chinese mythology, is China’s newest and most advanced programmable and deliverable machine of its kind.
