China Develops Radar That Can Detect Stealth Jets

China has tested quantum radar that could stealth aircraft and other objects within the range of 100 kilometers (62.1 miles).

The quantum radar of China was first developed by Intelligent Perception Technology Laboratory, a branch of defence and electronics firm China Electronics Technology Group Corporation (CETC).

The radar uses quantum entanglement photons, which means it has better detection capabilities than conventional systems. This means it can more easily track modern aircraft that use stealth technology or baffle enemy radar, various Chinese media reported Friday.

The radar, which was tested in mid-August, 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.

The technology is also beneficial in bio-medicine, since quantum radar requires lower energy and can be used to non-invasively probe for objects with low reflectivity, such as cancer cells.
