China has tested quantum radar that will be able to detect stealth aircraft and other objects within the range of 100 km.
The radar uses quantum entanglement photons, which means it has better detection capabilities than conventional systems, so it can more easily track modern aircraft that use stealth technology or baffle enemy radar, various Chinese media reported. 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 radar, which was tested in mid-August, was first developed by the Intelligent Perception Technology Laboratory, a branch of defense and electronics firm China Electronics Technology Group Corporation (CETC).
According to defenseworld.net, 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.
