量子隐形传态网络的广播与组播
Broadcast and multicast in quantum teleportation internet

摘要: 给出了广播与组播的物理原理．当Alice需要发送信息时，就向与自己相连的交换机发送一连接请求信号，交换机收到连接请求信号后通过检测目的地址判断是点到点的通信还是组播与广播；若目的地址是A类、B类或C类地址，则进行点到点的通信操作；若目的地址是D类地址或是有特殊意义的地址（本地网络，指定网络广播），则启动量子信息的广播与组播操作．广播与组播时的保真度随受话终端数的增加而减小，其极限为2／3．Abstract: The physical principle of broadcast and multicast is given. When Alice needs to send out an information, she sends out a conjunction claim signal to the switch that connects with hers. After receiving the conjunction claim the signal, the switch pass to examines the purpose address to judge whether it is a point-to-point communication or broadcast and multicast. If the purpose address is A or B or C address, then the switch carries on the correspondence operation of point-to-point; if the purpose address is a D address or an address （local or appointed network webcasting） with special meaning, then the switch carries on the correspondence operation of broadcast and multicast. With broadcast and multicast, the fidelity decreases with the increase of receiving terminal number, and its limit is 2/3.
