Abstract
This application provides a single-photon detection apparatus that includes a phase-reversed reflection branch, a single-photon sensing device, a phase-unreversed reflection branch. An input signal is divided into a first and a second input signals, and the two input signals respectively arrive at the phase-reversed reflection branch and the single-photon sensing device. The phase-reversed reflection branch is configured to perform phase-reversed reflection processing on the first input signal, to obtain a phase-reversed signal. The single-photon sensing device is configured to send the second input signal to the phase-unreversed reflection branch, and is further configured to sense a photon, generate photon information, and output a first branch signal. The phase-unreversed reflection branch is configured to perform phase-unreversed reflection processing on the second input signal to obtain a second branch signal. The first branch signal is superimposed with the second branch signal, to obtain the photon information.
