QUANTUM ENCRYPTION KEY DISTRIBUTION SYSTEM AND QUANTUM ENCRYPTION KEY RECEPTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a reception device which can perform consistent security certification regardless of characteristics of a photon detector.;SOLUTION: In a quantum encryption key distribution system, a quantum encryption key reception device which receives transmission signal light transmitted from a transmission device, comprises: a reference light source which generates reference light and has corrected characteristics; and quantum state measurement means which measures a quantum state of the transmission signal light by comparing the quantum state of the transmission signal light with the quantum state of the reference light.;COPYRIGHT: (C)2014,JPO&INPIT
