用大学物理知识诠释前沿科技——从光的偏振到量子通信ELABORATING FRONTIER TECHNOLOGIES USING COLLEGE PHYSICS KNOWLEDGES——FROM POLARIZATION OF LIGHT TO QUANTUM CONMUNICATION

摘要(Abstract):
在大学物理教学中以科技前沿应用为牵引,用大学物理的语言解释前沿科技进展的原理,拉近基础课和前沿应用的距离,可以促进学生学习物理的兴趣,加深学生对于基础物理原理的理解。本文以量子密钥分配为例,仅用大学物理中偏振的内容就解释了经典的BB84方案的基本原理,并对该方案的实际实现进行了阐述,旨在表明任何理论方案和实际实现都存在相当的距离。本文还介绍了量子通信领域的最新研究进展和目前主要的研究方向,以激发学生主动探索和进一步研究的兴趣和热情。本文是为基础物理原理和高新尖技术之间搭建桥梁的一次有益尝试,相关思路值得在新工科背景下的大学物理教学中推广。
