Quantum radar that can defeat Stealth technology?

Quantum radar is an emerging remote-sensing technology based on input quantum correlations (in particular, quantum entanglement) and output quantum detections




conventional radar transmit radio waves to reflect off of targets but a quantum radar instead uses entangled photons via fiber couplers,quantum dots or other methods.
The entangled photons bounce off of the targeted object back to the quantum radar which can extrapolate the position, speed, direction,radar cross section and other properties of the targeted object from the return time of the photon.







 because stealth aircraft are optimized for stealth against radio waves used by conventional radars,they would be much more susceptible to detection by the photon waves of a quantum radar.quantum radars defeat stealth by Subatomic particles not radio waves.



Subatomic particles don't care if an object's shape was designed to reduce traditional radio-wave based radar signature.quantum radar would also ignore traditional radar jamming and spoofing methods such as radio-wave,radar jammers and chaff.



US defense contractor Lockheed martin has been attempting to build its own quantum radar for long range detection since 2007 but still not succeeded. a major obstacle towards an operational quantum radar is the problem of quantum decoherence;as a quantum system like entangled particles spends more time in the environment,the longer exposure to the outside environment will cause the quantum system to 'decay'(to lose its quantum behaviour)



 There are two types of quantum radar:
1.Single-photon quantum radar
2.Interferometric quantum radar


State-owned China Electronics Technology Group Corporation (CETC) announced two years ago that its scientists had tested a quantum radar to a range of 100km (62 miles), which in theory would allow it to detect stealth aircraft at long distances.



The end of stealth? New Chinese radar capable of detecting ‘invisible’ targets 100km away

Only China got some  success  in developing quantum radar which is in very early stages only and still take time to be used for military purposes.

India is far away from developing this technology



Biggest advantage of quantum radar is that it can detect stealth fighters and bombers like F-22,F-35 and B-2 etc.,,.
