A superconducting single-photon detection system includes: a plurality of optical transmission paths through each of which a photon emitted from a light source is transmitted; a plurality of superconducting single-photon detectors (hereinafter referred to as 'SSPDs') that are independent of each other and in one-to-one correspondence with the optical transmission paths; and a superconducting logic circuit that multiplexes first pulse signals output from the SSPDs. A photon entry time at which the photon enters each of the SSPDs through a corresponding one of the optical transmission paths is different for each of the optical transmission paths, and a difference in the photon entry time between the optical transmission paths is greater than a pulse width of a corresponding one of second pulse signals output from the superconducting logic circuit.
