中文摘要：

本实验利用集成化的量子保密通信设备搭建了一个850 nm波长的全光纤量子密钥分发实验平台.该平台以光纤为量子信道,利用衰减后得到的单光子为信息载体,结合经典信道在通信双方随机生成量子密钥,从而完成量子密钥分发实验.本实验紧密结合近年来量子信息科研发展的最新成果,设计新颖,特色突出,有利于学生更加直观深入的了解量子密码技术和量子密钥分发过程.

英文摘要：

Using an integrated equipment,we build a quantum key distribution experiment platform.Taking fiber at 850 nm as quantum channel,the platform uses attenuated polarization modulated single photons as information carriers,and combines with the general communications channel to randomly generate quantum key.This experimental is colosely intgrated the latest achievements of quatum information research and development,and the experimental design is innovative and prominent features,which isonductive to students to intuitiely understand quantum key distribution process in depth.
