Successful development of domestic quantum computing ultra-low temperature sensor

2023-05-22   

The operation of quantum chips requires extremely strict temperature environments. How to monitor temperature changes in real-time and understand the operating status of refrigerators? Recently, the reporter learned from Anhui Quantum Computing Engineering Research Center that the domestic quantum computing ultra-low temperature sensor has been successfully developed and has been used in the domestic quantum computer. Zhang Junfeng, the head of the research and development team of Anhui Quantum Computing Engineering Research Center, introduced to the reporter: With the development of dilution refrigeration technology, dilution refrigeration technology at home and abroad is becoming increasingly mature, and the demand for temperature measurement is also increasing. In order to ensure that the quantum chip operates in a suitable temperature range, it is necessary to monitor the temperature environment of the quantum chip in real time. This sensor is like a 'quantum chip thermometer', which can monitor temperature changes in real time This ultra-low temperature sensor is fully independently developed by Hefei Benyuan Quantum and supports real-time temperature monitoring, with advantages such as high measurement accuracy. This product has a wide versatility and can be easily installed on the dilution refrigerator. At present, it has been used in the domestic quantum computer. Zhang Junfeng said that the quantum chip is the core device of quantum computer, and real-time monitoring of the temperature environment of the quantum chip can play a key role in the entire quantum computer system. The successful development of this domestic ultra-low temperature sensor has made the temperature measurement accuracy of China in the field of ultra-low temperature reach the international advanced level, and has taken an important step towards the full autonomy and control of quantum computer.
