Quantum radar

Quantum radar is a hypothetical remote-sensing method based on quantum entanglement.

One possible implementation of such technology has been developed and patented[1] by defense contractor Lockheed Martin.[2] It intends to create a radar system which provides a better resolution and higher detail than classical radar can provide.

The technology is hoped to work by using photon entanglement to allow several entangled photons to function as if a shorter wavelength was used to allow detection of small details while having an overall longer group wavelength that allows long distance transmission.[3]

One advantage of a quantum radar system is that it automatically detects deceptive jamming, which might otherwise go unnoticed.[4]
