随着全球首枚量子通信卫星“墨子号”的升空与量子通信加密光纤链路“京沪干线”的建成,我国量子通讯技术已走在世界前列。其中,量子不可克隆的原理让量子通信技术从根本上解决了通信安全的问题。2016年8月,中国成功发射了世界上首枚量子通信卫星“墨子号”;2016年12月,远距离光纤量子通信骨干网络“京沪干线”完成建设,并有望今年下半年开通使用。
With the launch of the world’s first quantum communications satellite “Mozi” and the establishment of a quantum communication optical fiber link “Beijing-Shanghai Route”, China’s quantum communications technology has taken the lead in the world. Among them, the principle of quantum non-cloning allows quantum communication technology to fundamentally solve the problem of communication security. In August 2016, China successfully launched the world’s first quantum communications satellite “Mozi No.”; in December 2016, the long-distance optical fiber communication backbone network “Beijing-Shanghai Mainline” was completed and is expected to be completed this year Six months after the opening of use.
