量子保密通信技术探讨

Study On Quantum Secure Communication

量子保密通信作为一项前沿技术得到了广泛的关注,但是,对一些与之息息相关的问题,诸如"量子信道是天然保密的吗?量子通信保密需要使用量子信息加密技术吗?身份认证能够在量子领域得到完全解决吗?"等,目前还没有形成共识。本文重点对量子保密通信的一些显著特点进行了分析和探讨。

Quantum crypto communication, as a leading-edge technology ,has attracted much attention However the common understanding has not been reached yet on the involved problems as ＂Is quantum channel is naturally secure？ Is it necessary for quantum communication security to employ quantum information encryption technology？ Is there a perfect solution of identity authentication in the quantum field ？ ＂ This paper has emphatically analyzed and discussed some outstanding characteristics in quantum crypto communications.
