英文摘要： Quantum illumination is a novel target detection technique proposed and demonstrated very recently. It exploits the strong quantum correlation of frequency and time entangled light.Under strong noisy background and high loss environments, the detection sensitivity and spatial revolution are drastically improved, compared to classical coherent laser target detection. Thus quantum illumination target detection has tremendous potentials in future practical applications. This project aims at to make deeply and detailed investigations on the concept and principle of quantum illumination. By employing entanlement swapping and single photon optical parametric amplication (OPA) in quantum illumination target detection, we explore the possiblities of providing solutions to the two key technology problems of time delay and synchronization of signal photon and idler photon and the scheme of optimal receiver. Research the methods of optimal receiving, develop experimental settings, and perform comparison experiments to demonstrate the quantum enhancement effect. This project would provide new principle, knowledge reserve, and technical support for space optical target detection.
