腔光子对多粒子纠缠产生的影响

Effect of cavity photons on the generation of multi-particle entanglement

Che-Ming Li, Y. -N. Chen, C. -W. Luo, Jin-Yuan Hsieh, Der-San Chuu

摘要:

本文对多粒子纠缠产生的原因进行了研究。我们研究了通过单个微腔模独立耦合的单量子阱激子在对腔场态进行一系列条件测量时如何演化到最大纠缠态。我们首先研究了腔光子对双激子Bell态和三激子W态纠缠纯度的影响。推广到多激子W态,然后推导出解析。我们的结果为研究多粒子集体效应的根本原因铺平了道路。

英文摘要:

A study on the cause of the multi-particle entanglement is presented in this work. We investigate how dot-like single quantum well excitons, which are independently coupled through a single microcavity mode, evolve into maximally entangled state as a series of conditional measurements are taken on the cavity field state. We first show how cavity photon affects the entanglement purity of the double-exciton Bell state and the triple-exciton W state. Generalization to multi-excitons W states is then derived analytically. Our results pave the way for studying the crucial cause of multi-particle collective effect.
