摘要
The BB84 protocol[1],as the first and the most well-known quantum key distribution(QKD)protocol,has opened up an era of secure commu-nication using quantum methods,by providing information-theoretical secure key distribution[2].In the 2000s,continuous-variable QKD(CV-QKD)was proposed as an alternative approach,and it is now going through a booming period because of its compatibility with the tele-com industry[3].
