Dear All,
Applications where background thermal radiation is low and object return reflections are weak may benefit from quantum radar. So I was curious, who if any, might be exploiting this for radioastronomy? Using a beam of entangled photons (squeezed light) to illuminate has advantage that phase error (from shot noise) is lower than that in classical coherent radar beams. This would offer greater sensitivity for detecting smaller objects and estimating their distances. I'm looking at materials and circuits to generate and detect entangled photons - eg a 20 Gsps 4-bit digitiser as part of the receiver. One potential application might be to track asteroids in the solar system, or even detect objects before they enter the solar system - a key question being achievable performance. Anyone aware of interest in this for astronomy? Many thanks, Neil -- You received this message because you are subscribed to the Google Groups "[email protected]" group.
