Optical Parametric Amplifier Detection for Quantum Illumination
Jingxin Wang, Kon Max Wong
Quantum illumination (QI) is a technique exploiting the quantum entanglement between the transmitted signal and the idler to enhance the detection performance of a quantum radar over the classical radar. Here, we propose the double optical parameter amplifier (OPA) detector for QI so that the effect of entanglement between the idler and the returned signal beams is maximized. We show here how even when a weak returned signal is embedded in a large background noise, the probability of detection can be significantly increased.
