Ad hoc quantum network routing protocol based on quantum teleportation

In this paper, a quantum communication routing protocol is designed for quantum ad hoc network. This protocol is on-demand routing based on EPR numbers shared by adjacent nodes, concerning that it is a limited source. When quantum channel is established, quantum states from one quantum device can be teleport to another even when they do not share EPR pairs wirelessly. Part of information transferred by classic channel can be dealt with using simple logics. In this way, the goal of safety communication between source and destination is realized, improving the weakness of ad hoc network such as Eavesdropping and Active attacks. In terms of time complexity, the mechanism transports a quantum bit in time almost the same as the quantum teleportation does regardless of the number of hops between the source and destination.
