量子密码术是一门崛起的新兴技术,其传输的安全性基于量子力学的Heisenberg不确定原理.而其中空间量子密码通信以其近期迅猛的发展和广阔的前景备受瞩目.本文从量子密码术的基本原理出发,综合叙述了空间量子密码通信的发展和最新成果.

Quantum cryptography is an emerging technology The security of the transmission is based on Heisenberg's uncertainty principle of quantum mechanics. Especially, free-space quantum key distribution is the focus of attention for the recent rapid improvements in experiments and the wide application outlook. In this paper, a review is presented about the developments of quantum key distribution and its current experimental research, from its basic principle
