摘　　要：2007年4月2日,国际上首个量子密码通信网络由中国科学家在北京测试运行成功。这是迄今为止国际公开报道的唯一无中转,可同时、任意互通的量子密码通信网络,标志着量子保密通信技术从点对点方式向网络化迈出了关键一步。这次实验的成功,为量子因特网的发展奠定了基础。文章阐述量子密码的产生、量子密码学的基本原理、该领域的实验研究及研究成果,最后指出量子密码通信将是保障未来网络通信安全的一种重要技术。China＇s first quantum cryptography network has been successfully tested in Beijing, the Chinese Academy of Sciences announced on April 2, 2007. It is the only fully-connected quantum network that could make simultaneous communications without any relay ever reported in the world, according to experts. The feat is a crucial step towards the practical usage of quantum cryptography from the point-to-point network. The success of this experiment, laid the foundation for the development of quantum Internet. This paper describes the generation of quantum cryptography, the basic principle of quantum cryptography in the field of experimental research and research results, and finally pointed out that quantum cryptography will be an important technology to protect the security of network communication.
