AI Technical Summary
Existing quantum radars suffer from channel mode spot distortion due to atmospheric loss and turbulence in free space target detection, affecting detection efficiency and making it difficult to achieve high-resolution target imaging.
A polarization-entangled light field is generated by four-wave mixing. Polarization-entangled light is generated through a polarization-entangled source system. A polarization controller is used to form entangled light with a specific polarization. The light is then detected by combining optical transmitting and receiving antennas to achieve signal light matching with local optical modes and resist the influence of atmospheric turbulence.
This improved the imaging resolution of quantum illumination, solved the problem of poor matching between the signal light at the detector end and the local light mode, realized high-precision target detection at long distances, and promoted the practical application of quantum illumination.
