A delayed commutation switch is proposed that can solve the problem of switching time in packet switching networks with the help of some local ancillary qubits and superdense codes.
Abstract
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.
