According to the South China Morning Post, the ultra-low noise device was developed at the Quantum Information Engineering Research Center in Anhui Province. The detector is capable of detecting single photons — the smallest particles of light — making it indispensable for quantum communications, navigation, and national defense systems.
According to the publication, the technology will allow China to create quantum radars that can track low-profile aircraft, including the American F-22. Unlike traditional radars, such systems analyze reflected photons, detecting even false signals and maintaining their own secrecy.
Experts note that the launch of mass production of the detector strengthens China's position in the global technology race. The large-scale introduction of quantum surveillance and communication systems can be an important step towards the technological independence of the country and increase its defense potential.
