China has stealth-defeating quantum radar: Reports

Beijing, Sep 9 (IANS) A Chinese firm has developed and tested a radar system that uses quantum entanglement to beat the stealth technology of modern military craft, a media report said.state media said.

The first Chinese quantum radar was developed by the Intelligent Perception Technology Laboratory of the 14th Institute in CETC -- Electronics Technology Group Corporation, a defense and electronics firm -- Xinhua news agency reported.

The radar was tested in mid-August, the report said.

The system was able to detect a target at a range of 100 kilometers in a real-world environment. 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 technology may also find use in biomedicine, since quantum radar requires lower energy and can be used to non-invasively probe for objects with low reflectivity, such as cancer cells.

Earlier this year, China launched the world's first quantum communications satellite, which uses quantum entanglement for cryptography.
