本文给出量子光通信的基本概念与机制。该系统为一非古典通信系统。信道参数(如信息容量和探测灵敏度等)的最终物理限制取决于系统的量子参量,因而比当前已发展的光通信系统具有更大的技术潜力。本文还介绍了已有的实验结果及光明的应用前景。希望本文对光纤通信的基础研究有所俾益。
This paper presents the basic concepts and mechanisms of quantum optical communication. The system is a non-classical communication system. The final physical limitations of channel parameters (eg, information capacity and detection sensitivity, etc.) depend on the quantum parameters of the system and therefore have greater technical potential than the currently-developed optical communication systems. This article also introduces the existing experimental results and bright application prospects. I hope this article has some benefits to the basic research of optical fiber communication.
