Abstract
A method and apparatus for authenticating a radar return signal include: generating an outgoing radar beam; generating a pair of entangled photons comprising a signal photon and an idler photon; combining the signal photon with the outgoing radar beam to generate a combined beam; sending the combined beam towards a target; receiving a return beam; detecting the signal photon from the return beam by a quantum illumination receiver; and making a joint detection with the idler signal.
