自由空间量子通信试验系统设计与实现

摘要

With the booming development of quantum communication ,quantum key distribution which based on free space has become an important research topic in quantum information science and quantum mechanics displines .According to the quantum communication experiment system's process control and data processing needs ,we construct a software system platform .This paper introduces the design and work flow of the system ,and design the overall framework and main func-tion module of the system .The test system was tested ,and the test results show that the key rate is greater than 1 . 5kbps ,can meet the system's requirements for the work .%随着量子通信的蓬勃发展，基于自由空间的量子密钥分发已成为量子信息科学和量子力学学科的重要研究课题。针对量子通信试验系统中的流程控制以及数据处理需求，构建了软件系统平台。介绍了系统的设计目标和工作过程，给出了软件系统的整体框架和主要功能模块设计。对试验系统进行了测试，测试结果显示密钥成码率大于1．5kbps ，可以满足系统的工作要求。
