在新时代新工科教育改革势在必行的大背景下，结合我校工科类为主的大学物理教学特点，提出了“新时代新工科大学物理教学体系”改革.新时代需要工科毕业生更加了解现代前沿技术，我们在原有的大学物理教学基础上扩展了一系列现代物理相关的新兴技术，本文以量子通信技术为例.量子通信是量子力学和经典通信相结合产生的新的交叉技术，由于量子具有“不可分割”“不确定性”“不可克隆”等特性，量子通信能够实现无条件安全，使它成为一种全新的安全通信技术.量子通信作为量子技术之一，一直以来给人以‘高、冷、神’的感觉，使非专业人士望而却步.本文正是通俗易懂讲清楚量子通信的基本原理，在原有的大学物理教学中加入这些新兴的技术，使得大学物理更加贴近前沿技术.

Under the background that the education reform of new times and new engineering is imperative，combining with the characteristics of college physics teaching in our engineering-dominated university，the reform of“college physics teaching system of new times and new engineering”is proposed. The new times require engineering graduates to better understand modern cutting - edge technologies. On the basis of the original college physics teaching，we have expanded a series of new technologies related to modern physics. This paper takes quantum communication technology as an example. Quantum communication is a new cross technology which combines quantum physics and classical communication. Due to the features of“indivisibility”，“uncertainty”and“No-Cloning Theorem”， quantum communication can realize unconditional security， making it a new security communication technology. As one of the quantum technologies，quantum communication has always given people the feeling of“Unattainablez”，which makes non-professional people flinch. This paper is just to explain the basic principles of quantum communication in a simple way. These new technologies are added into the old college physics teaching，making college physics closer to the frontier technology.
