Abstract

The paper relates to a quantum radar deployment by the Born-Feynman path integrals approach based on quantum dots. The radar system comprises a quantum dot-based entangled photon generator, a transmission module, a delay line, a detection module, and a signal processing unit. The quantum dot-based entangled photon generator produces entangled photon pairs via spontaneous parametric down-conversion or stimulated emission. The signal transmission module, equipped with a microwave antenna and beamforming elements, directs the signal photon toward a target. The delay line module synchronizes the retained idler photon with the returning signal photon, preserving quantum coherence. The detection module collects the reflected signal photon and uses a cryogenically cooled superconducting nanowire single photon detector (SNSPD) for detection. Finally, the signal processing unit analyzes the quantum correlation between the scattered and idler photons to enable precise quantum state comparison.
