量子通信中量子密钥分发教学仿真实验设计

Design of quantum key distribution teaching simulation experiment in quantum communication

量子密钥分发的无条件安全使其在国防军事、金融银行等多个领域发挥着重要作用。文章从实验整体设计、实验教学流程设计、层次化实验任务设计入手,基于高斯调制连续变量量子密钥分发协议和离散调制连续变量量子密钥分发协议,将MATLAB作为仿真实验平台,设计了针对通信工程专业本科生的量子密钥分发教学仿真实验,并就学生实验结果进行了分析,可为量子通信教学实验设计与研究提供参考。

The unconditional security of quantum key distribution makes it play an important role in many fields,such as national defense, military, finance and banking. Starting with the overall design of the experiment, the design of the experimental teaching process and the design of the hierarchical experimental task, based on the Gaussian modulation coherent state continuous variable quantum key distribution protocol and the discrete modulation coherent state continuous variable quantum key distribution protocol, taking MATLAB as the simulation experiment platform, this paper designs the quantum key distribution teaching simulation experiment for the undergraduates majoring in Communication Engineering, and analyzes the experimental results of the students. It can provide a reference for the design and research of quantum communication teaching experiment.
