量子信息技术因其卓越的特性而受到高度重视，被认为是未来信息技术发展的必然趋势，而具备量子物理背景的专业人才培养就显得极为重要.但是，由于量子信息技术具有抽象性、交叉性、前沿性和复杂性等特点，针对本科生开展相关实验教学具有一定挑战.中山大学从2018年开始在该方面进行了初步探索，针对高年级本科生开设了量子密钥分发等实验课程.本文基于笔者的教学工作，对量子密钥分发实验课程进行了介绍，探讨了其中的难点以及解决方案，希望通过本文探讨，能够对量子信息技术的教学工作有一定帮助.

Due to its special advantages，quantum information technology has attracted more attentions，and is considered as the trend of information technology.Thus，the training of students and engineers with a background in quantum mechanics is considered as a strategic task for future talent reserves.However，due to the abstraction，intersectionality，cuttingedge and complexity，the experimental course is difficult for undergraduate students.In this paper，the course，quantum key distribution，in Sun Yatsen University is introduced and it is hoped to be of some help to the teaching and training of quantum information technology.
