摘      要：A relatively simple plug-and-play control system of quantum key distribution(QKD) based on PCI7300 card is demonstrated,including mechanism design,key generation and key *** system works very well at the repetition frequency of 1 MHz,and the key generation rate is 100 k/s.A visibility of better than 95% over 50 km-long fiber at 1.31 μm is obtained,which is stable under ordinary lab conditions for 24 h without any feedback control or *** presented system is a quite promising candidate to realize the QKD in the future.
