What is quantum radar?


Stealth technology counteracts radar in one of two ways: either it is shaped so it deflects most of the radar beams away from the detector, or it emits a jamming signal that confuses the radar detector with noise it can't separate from the original signal.

Answer and Explanation:

Quantum radar is a theoretical anti-stealth technology. The radar would generate a pair of particles with quantum entanglement. Quantum entanglement is a state where, if you learn anything about one particle, you will know the state of its entangled particle. One-half of the pairs are then converted into microwaves and sent out as radar. When it bounces back to the detector, it will be measured against the other half of the particles so the radar will always be able to pick up its own signal, defeating any stealth technology that tries to obscure it.
