摘　　要：利用纠缠交换介绍了量子交换机的工作原理,利用量子交换机逐一进行纠缠交换可以建立Alice和Bob的量子连结.只要将现行的交换机等互联设备增加纠缠粒子对发生器,在网络空闲时保持和相邻设备间的量子连结,就可将经典的互联网升级为量子隐形传态互联网.在量子隐形传态互联网中其路由的选择仍可利用经典互联网的路由算法;在固定路由选择策略中路由选择可与量子信道的建立同步进行,在动态路由选择策略时可先选择路由以生成路由器序列表,然后根据该路由器序列表逐一进行纠缠交换就可以建立Alice和Bob的量子连结.The principle of the quantum switch is introduced by means of entanglement swapping.With the help of quantum switch operating entanglement swapping one by one,quantum correlations between Alice and Bob can be established.Adding entangled particle generator into conventional interconnection equipments,such as switch,and keeping quantum correlations between adjacent devices in the network leisure time,one can upgrade the classic internet to quantum teleportation internet.In quantum teleportation internet,the routing is selected also by utilizing the routing algorithm of classical internet.The routing selection can be synchronized with the establishment of quantum channel in static routing strategy.When the dynamic routing strategy is selected,quantum switch first selects a route to generate a router sequence table and then operates entanglement swapping one by one according to the table to establish the quantum correlations between Alice and Bob.
