QUANTUM ENCRYPTION KEY DISTRIBUTION SYSTEM, TRANSMISSION APPARATUS APPLIED TO SAME, AND CONTROL METHOD OF TRANSMISSION APPARATUS

摘要

The present invention discloses a quantum encryption key distribution system, a transmission apparatus applied to the same, and a control method of the transmission apparatus. The quantum encryption key distribution system can compensates a phase error quickly and efficiently, caused by a temperature change of an interferometer located in a receiving end. The transmission apparatus of the quantum encryption key distribution system includes: a pulse generation unit having a phase-shifting function of selectively phase-shifting a clock signal; a phase modulation unit randomly modulating a phase of at least one of two photon pulses and transmitting the same to the receiving end; a checking unit checking the temperature change; and a feedback control unit controlling a specific time interval that the two pulses have.;COPYRIGHT KIPO 2016
