作为目前量子物理区域研究的重点及热点,量子通信已然受到人们的极大关注。量子通信是一种新兴的通信方式,它是利用量子之间的相互影响效应进行信息传递的。作为目前广泛关海珠的新兴研究领域,如何保证量子保密通信的安全性,将其应用到实际生活中,成为目前主要研究的问题。本文在阐述量子通信原理的基础上,叙述了量子密码术在量子保密通讯方面的重要作用,通过分析量子保密安全协议,简要介绍量子因特网的构成,并对其将来的应用及发展做出展望。 As the focus and hotspot of the current research on quantum physics, quantum communication has drawn much attention from people. Quantum communication is a new way of communication, it is the use of the interaction between the quantum effect of information transmission. As an emerging field of research on Guanghzizu, how to ensure the security of quantum secure communication and apply it to real life has become a major research issue at present. Based on the principle of quantum communication, this paper describes the important role of quantum cryptography in quantum secure communication. By analyzing the quantum security protocol, it briefly introduces the structure of quantum internet and prospects its application and development in the future.
