GATING APPARATUS FOR SINGLE-PHOTON DETECTOR, AND QUANTUM COMMUNICATION DEVICE

Provided in the present invention are a gating apparatus for a single-photon detector, and a quantum communication device. The gating apparatus comprises: a system synchronization unit, which is configured to acquire a clock of a quantum communication system; and a programmable controller, which is configured to generate periodic gating signal sequences that are synchronized with the clock of the quantum communication system, wherein gating signals in each gating signal sequence are spaced apart from each other by a predetermined duration, such that a single-photon detector can operate in a corresponding Geiger mode for a received optical pulse, and the predetermined duration is an optical path difference between a long arm and a short arm of an unequal-arm interferometer that is used for performing phase encoding in the quantum communication system. La présente invention concerne un appareil de déclenchement pour un détecteur monophotonique, ainsi qu'un dispositif de communication quantique. L'appareil de dé
