摘要
A transmitting apparatus in a quantum key distribution system, includes: an optical interferometer to receive a single-photon pulse inputted from a light source and to provide two optical paths with a predetermined path difference, the two optical paths used for the single-photon pulse to pass through the optical interferometer; and an optical phase modulator to perform a temporal differential phase modulation of the single-photon pulse which has passed through the optical interferometer, wherein the single-photon pulse, after passing through the optical interferometer, has a probability distribution divided into two separate regions in time domain.
