摘　　要：将费曼路径积分理论引入量子力学教学,用来分析光子干涉现象.对非简并的两光子和三光子干涉的关联函数进行了推导,并对干涉结果进行了模拟.模拟结果显示,非简并的多光子干涉是多光子聚束和量子拍效应叠加的结果.The Feynman’s path integral theory is introduced into quantum mechanics teaching,and used to analyze photon interference.The correlation functions of nondegenerate two-photon and three-photon interference are derived.The results of interference are simulated.The simulate results show that multi-photon interference of nondegenerate photons results from the superposition of multi-photon bunching and quantum beating effect.
