摘要
本文应用伪随机序列， 提出了一个基于测不准原理的量子密码术新方案， 使得量子密钥传递过程的理想传输效率达到 １００％ 。在保持满意的安全性的同时提高了传输速率。采用该方案可以实现远距离量子保密通信。
We introducing a pseudo random sequence into quantum ceyptography and propose a novel scheme based upon Heisenberg′s Principle. The key distribution procedure is expedited and its theoretic transmission efficiency is raised to 100%, meanwhile a satisfactory security level is still maintained. The scheme can be generalized to realize the long range quantum secure communication.
