China Tests First Quantum Radar

China has tested its first quantum radar which could detect objects, including stealth aircraft, within the range of 100 kilometres.

The first Chinese quantum radar was developed by the Intelligent Perception Technology Laboratory of the 14th Institute of China Electronics Technology Group Corporation (CETC).

The device employs single photon detection technology.

Quantum radar is a device that uses quantum entanglement photons to provide better detection capabilities than conventional radar systems.

The method would be useful for tracking targets with a low radar cross section, such as modern aircraft using stealth technology or targets employing active countermeasures to jam or baffle enemy radar.

China has earlier launched the world’s first quantum communications satellite, which uses quantum entanglement for cryptography.
