The simulation of single photon and applied to the design of quantum antenna

Abstract

Starting from the Maxwell’s equations, taking the transverse electromagnetic wave as an example, we use the finite difference time domain method to simulate the generation and transmission process of single photon. The entanglement phenomenon of two single photons during transmission is also analyzed. The single photon is transmitted in time sequence or in time slot of frame structure. In the process of transmission, the W entangled state of photon can also be formed. Then, we design a planar square quantum antenna array, and characterize multi photon entangled state images.
