摘要 文章综述了连续变量量子密码术的基本原理,突出了其在光源制备、光子探测以及量子密钥生成的码率等方面相对于单光子量子密码术的优越性,给出了连续变量量子密码术的安全性以及对线路噪声的具体要求,提出了连续变量量子密码术目前所面临的主要困难和今后的发展前景. This paper describes the primary principle of the continuous - variable quantum key distribution, comparing to single photon quantum key distribution, it is advantageous in preparing light sources, detecting photons and enabling higher key distribution rates. The security of this protocol and the limit of the excess noise have been shown in order to guarantee the key securely. Finally, we pick up the obstacle which will face and point its direction.
