Entangled Photons Based Particle-Level Temporal-Spatial Matching Processing in Quantum Radar

With the continuous development of quantum technology, entangled signal has been used in more and more fields. Due to the unique temporal-spatial correlation characteristics of entangled signal, it provides promising solutions to problems such as super-resolution and anti-interference. Especially in the context of weak signal, the entangled signal-based sensing is more prominent. In this paper, we present a quantum imaging framework based on particle level matching processing under the correlation characteristics of entangled photons. The temporal-spatial correlation property of the entangled photon is used to realize the matched filtering to accumulate the weak signals in time domain and reconstructed the target image in spatial domain.
