摘要
从量子力学两个基础实验———电子双缝干涉实验、Stern -Gerlach实验出发 ,引出量子信息理论的两个新概念———量子退相干与量子纠缠。并详细介绍了量子退相干概念和量子纠缠概念以及它们在量子信息领域中的应用。这样在学生可接受的范围内把物理前沿的新概念引入到了实验教学 ,从而拓宽了学生的知识面 ,加深了对物理概念的理解 ,发掘了基础实验的新效用。
Based on quantum mechanical two base experiments,electrical two-slit interference experiment and Stern-Gerlach experiment, two new concepts of quantum communication theory,quantum decoherence and quantum entanglement are derived, and the new activity was given to the base experiments.So,within the acceptable sphere of students,new conceptions of advanced physics are brought into experiment lessons,which can enrich students' knowledge.It gets a deeper understanding of physical concept,explores the new use of basic concepts.
