摘要

提出了一种利用四组分纠缠态光场实现开放传输的量子离物传态网络的实验方案。将未知量子态在输入节点与纠缠态光场的一个子模进行联合测量后,可以根据需求选择经典通道的传输方向,在其他任意一个节点处恢复出该量子态。通过计算由三种不同传输方式恢复出的量子态的保真度,证明了三种方式均可成功实现量子离物传态,达到开放传输的目的。

Abstract

An experimental scheme for realizing open-destination quantum teleportation network is proposed by means of the four-partite entangled states of light. After the joint measurement of the unknown quantum state with a sub-mode of the entangled state light field in the input node, one can recover this unknown state at any other nodes by choosing a transmission direction of classical channels according to the requirement. Through the calculations of the quantum state fidelity in three different transmission directions, it is proved that the quantum teleportation by these three means is all possible and the open transmission is realized.
