摘要/Abstract

摘要： 采用对自发参量下转换过程产生的光子对的量子态和光场的非纠缠态描述,分析了由自发参量下转换过程产生的四光子的德布罗意波长测量的实验,得到了与实验观测相一致的结果。这一结果进一步验证了对自发参量下转换过程产生的光子对的量子态和光场的非纠缠态描述的正确性。

关键词: 四光子态, 德布罗意波长, 纠缠态, 自发参量下转换过程

Abstract: Experimental results of four, photon de Broglie wavelength measurement are analyzed based on a local description for the quantum state and optical field of photon pairs generated from spontaneous parametric down, conversion (SPDC). The agreement between the theoretical results and reported experimental is found.

Key words: four, photon state, de Broglie wavelength, entangled state, SPDC
