Moreover , it may have applications in quantum dense coding and quantum cryptography 另外，量子隐形传态在量子稠密编码和量子密码术中有许多应用。
Quantum communication is a rising interdisciplinary field which combines classical communication and quantum mechanics 量子密码术是经典通信和量子物理相结合的一门新兴交叉科学。
There are several classical processes in quantum key distribution to sift information and insure the security of keys 量子密码的传输离不开经典通道的通讯，它需要经典通道的通讯来筛选信息，确保安全。
The post - processing procedures include sifting , estimation of error rate , reconciliation , confirmation and privacy amplification 量子密码传输中需要的经典信息包括筛选、误码率估计、协调、检验和秘密放大。
Nevertheless , quantum cryptography , which is based on quantum physics , has been proved to be an effective technique for secure key distribution 然而，基于量子物理原理的量子密码学已被证明是保密通信中密钥安全分配的有效手段。
Quantum cryptology is one of the nearest study tasks in cryptology technology , its development do active promotion to the progress of cryptology theory 而量子密码术是密码学技术的较新的研究课题，它的发展对推动密码学理论发展起了积极的作用。
The realization issues of these protocols important for the security aspect are discussed and a review of current experimental progresses in the field is presented 从安全方面讨论了量子密码协议实现方案存在的一些问题，并介绍了当前实验研究的进展。
Heisenberg " s uncertainty principle guarantees that no eavesdropper can escape detection because of the fact that the eavesdropper cannot measure the signals without disturbing them 根据海森堡测不准原理，任何窃听者无法窃听量子密码通信中的信息而不被发现。
It also allows one to run quantum key distribution in a simulating mode without the need for any specialized hardware . the software will be improved to support the experiment setup 量子密码软件不仅可以模拟bb84 、 b92协议的密码通讯的整个过程，也可以实现文件传输功能，还要和实验相连接。
In this paper , we firstly describe the recent research progress and the theory basis of quantum cryptography , then introduce quantum key distribution ( qkd ) and eavesdropping attacks on the qkd 本文首先描述了量子密码学的最近研究进展及其理论基础，接着介绍了量子密钥分配以及在它之上的窃听攻击。
