摘要
使用光学分束器和单光子源,利用单光子态和真空态制备出了纠缠单光子态.利用光学分束器作用和单光子探测,实现了三个通讯伙伴之间的纠缠转移.提出了一个关于纠缠单光子态的量子隐形传态方案.在这个方案中,被传送的是一个未知的单光子纠缠态.通讯双方使用的量子信道是两个单光子纠缠态.通过使用分束器作用和对输出态进行光子测量以及在经典信息的帮助下,纠缠转移和量子隐形传态的过程被完成.
A method of generating the single-photon entangled states of a single photon state and a vacuum state through utilizing optical beam-splitter and single-photon source is described. A setup for realizing entanglement translation of the single-photon entangled state is designed. A proposal is presented for teleporting an unknown single-photon entangled state. In this proposed, the two single-photon entangled states is utilized as the quantum channel. The process of the entanglement translation and quantum teleportation are achieved by using the 50/50 symmetric beam splitters and the photon detectors with the help of classical information.
