QUANTUM-KEY-DISTRIBUTION RECEIVING DEVICE AND METHOD FOR USING SINGLE-PHOTON DETECTOR |
| 摘要 |
There is provided a quantum-key-distribution receiving device used in a quantum key distribution system that utilizes a pair of quantum-entangled photons including a signal photon and an idler photon, the quantum-key-distribution receiving device including a single-photon detector in which a secure-key generation rate is dependent on a first performance index η/(1+Pa), η denoting a detection efficiency and Pa denoting an after-pulse probability. |
