Abstract: False radar target detection incudes: generating a pair of entangled photons as a probe photons and idler photons; preparing a plurality of photon states; using the ancilla photon states to encode the probe photons and the idler photons; encoding the probe photons and the idler photons with the ancilla photon states; storing the idler photons; transmitting the probe and ancilla photons as a radar signal; receiving a return radar signal from the target; performing a quantum error detection on the return radar signal to determine whether there is an error in the received radar signal as a result of decoherence in the return signal; and correlating the probe signal, the idler states and analyzing the errors detected on the return radar signal to determine whether the target is a true target when there is low decoherence in the return radar signal.
