Quantum radar is a remote-sensing method based on quantum entanglement. The most convincing model has been proposed by an international team of researchers. This team designed a model of quantum radar for remote sensing of a low-reflectivity target that is embedded within a bright microwave background, with detection performance well beyond the capability of a classical microwave radar. By using a suitable wavelength converter, this scheme generates excellent quantum correlations (quantum entanglement) between a microwave signal beam, sent to probe the target region, and an optical idler beam, retained for detection. The microwave return collected from the target region is subsequently converted into an optical beam and then measured jointly with the idler beam. Such a technique extends th
