走近量子通信

Approaching Quantum Communication

文章首先介绍了量子通信的基本概念:量子、测不准定理、量子不可复制、量子纠缠、量子隐形传态、量子密钥分发等,基于这些概念分析了隐形传态的量子通信原理,在此基础上结合绝对安全、超大容量、超远距传输、无需介质、近实时传送等优点介绍了量子通信的应用情况,最后对量子通信的发展现状进行了总结。

This article first introduces the basic concepts of quantum communication,that are quantum,quantum uncertainty theorem,quantum non copy,quantum entanglement,quantum teleportation,quantum key distribution and so on. Based on these concepts,the quantum communication principle of teleportation is analyzed. And on the above basis,combining with the advantages of absolute safety,large capacity,ultra long distance transmission,without medium,near real-time transmission,the application of quantum communication is introduced,then the development status of quantum communication are summarized.
