摘要
利用卫星来分发单光子(或纠缠光子对)的方法为远程量子通信网络提供了一种独特的解决方案。这将克服现有的光纤和陆上自由空间链路所带来的距离限制,实现真正意义上的全球量子通信。本文对这种设想进行了分析,证明这种设想有很高可行性。
Using satellites to deliver single photon or entangled photon pairs is a unique solution to realize long-distance quantum communications networks. This solution is able to overcome the disadvantage of transmission distance when using fiber and terrestrial free space optical links. And global quantum communications may be realized in this way. A scheme of using satellite to deliver single photon or entangled photon pairs is described, and the possibility of the scheme is proved.
