China makes prototype fridge able to reach quantum computing temperatures
- Almost ‘absolute zero’ device will help develop sector needing extremely cold conditions
- Home-grown means another move closer to nation being technologically self-reliant

Ji Zhongqing, a research fellow at the academy, told Science and Technology Daily on Tuesday: “The team will continue to improve technology so that a new generation of refrigerators under construction will reach the quality of imported products in terms of usability and stability.”
Xinhua, also on Tuesday, said the machine can realise an ultra-low temperature just 0.01 degrees Celsius higher than absolute zero, which is -273.15 degrees Celsius. Absolute zero is the lowest possible temperature, where nothing can be colder.
Qubits, or the central part of quantum computers, must be kept very cold inside a special refrigerator near the temperature where atoms stop moving. China has invested huge amounts in quantum computing.
