摘　　要：为了研究量子通信系统,提出了一种基于光开关的量子交换器,它是量子通信网络的节点.该量子交换器主要由交换模块、控制模块和输入输出模块组成.它在量子通信网络的发信者与收信者之间建立光子链路,为通信双方提供量子信道,用于传输量子信息.搭建了量子交换器平台,并用微弱光源对该量子交换器平台进行了测试,结果表明该量子交换器具备了量子通信网络中节点的功能,能够成功实现量子通信网络的功能.In order to study system of quantum communication, a scheme of quantum switch based on optical switch is presented, which is the node of quantum communication network. The quantum switch is mainly made up of optical crossing module, switch controller module and in-out module. It builds the photon link between sender and receiver of quantum communication network, and provides quantum channel for transferring quantum information between them. The experiment bed of this quantum switch is established, and the test result with weak optical resource indicates that this quantum switch can be used for quantum communication network and can also realize the function of quantum communication network.
