摘　　要：针对量子纠缠的产生方式,着重介绍了常见的3种类型的量子纠缠源制备方法,包括基于自发参量下转换(SPDC)制备量子纠缠源、基于四波混频(FWM)效应制备量子纠缠源和基于量子点制备量子纠缠源,分别分析了其原理、优缺点及其质量指标,最后展望了量子纠缠源制备方法的研究与应用方向。Aiming at the generation mode of quantum entanglement,three kinds of common preparation methods of quantum entanglement sources are introduced emphatically,including the preparation of quantum entanglement sources based on spontaneous parametric down conversion(SPDC),four wave mixing(FWM)effect and quantum dot.The principle,advantages,disadvantages and quality indexes of quantum entanglement source are analyzed respectively.Finally,the research and application direction of preparation methods of quantum entanglement source are prospected.
