Quantum chips have "thermometers": domestic ultra-low temperature sensors have been successfully developed

CTOnews.com May 18 news, quantum computer is the frontier field of future computing technology. Quantum chip is the core device of quantum computer, which has high requirements for temperature environment.

According to CCTV news, in order to monitor the temperature change of the quantum chip in real time and understand the running state of the refrigerator, researchers at the Anhui Quantum Computing Engineering Research Center have successfully developed a domestic quantum computing ultra-low temperature sensor, which the researchers vividly call the "quantum chip thermometer."

The sensor is completely independently developed by Local Quantum Computing Technology (Hefei) Co., Ltd., supports real-time temperature monitoring, can accurately measure the temperature range of 10mK~40K, is suitable for all kinds of dilution refrigerators, and is easy to install and use. at present, it has been put into use in domestic quantum computers, which provides a key guarantee for quantum computer systems.

CTOnews.com noted that this is an important achievement that China's temperature measurement technology in the field of extremely low temperature has reached the international advanced level, and it is also an important step for our country to realize the autonomous control of quantum computers.
