| 摘 要： | 提出了一种基于贝尔态的确定性量子密钥分配协议.它建立在纠缠量子系统的内部关联的基础上,双方通过共享纠缠量子系统和做单粒子量子测量建立起共享的密钥.与传统的只能生成随机字符串作为密钥的量子密钥分配协议不同,利用该协议,双方可以以任意指定的字符串作为共享的密钥.量子力学的定律保证了该协议的无条件安全性.除了单粒子量子测量之外,不需要做任何复杂的量子操作,因此它更容易实现,健壮性更好.

| Abstract: | A deterministic quantum key distribution protocol(QKD) based on the Bell States is presented,based on the domestic correlation of entangled quantum system. The two parts share a key by sharing entangled quantum systems and performing single-particle quantum measurements. Unlike the traditional QKD protocols in which the key is a random binary string,this protocol can make the two parts share a predetermined string as the key. The laws of quantum physics guarantee the unconditional security of this protocol. There are no complex quantum operations except single-particle quantum measurement. So it's easier to carry out in practice with better robust. |
