In the same way that classical computer networks connect and enhance the capabilities of classical computers, quantum networks can combine the advantages of quantum information and communication. We propose a nonclassical network element, a delayed commutation switch, that can solve the problem of switching time in packet switching networks. With the help of some local ancillary qubits and superdense codes, we can route a qubit packet after part of it has left the network node.
如同经典计算机网络连接并增强经典计算机的能力一样，量子网络可以结合量子信息与通信的优势。我们提出一种非经典网络元件，即延迟换向开关，它能够解决分组交换网络中的交换时间问题。借助一些本地辅助量子比特和超密集编码，我们可以在量子比特包的一部分离开网络节点后对其进行路由。
