Quantum wireless wide-area networks and routing strategy

According to multistage quantum teleportation, we here propose a quantum routing scheme which teleports a quantum state from one quantum device to another wirelessly even though the two devices which do not share entangled photon pairs mutually. By the quantum routing scheme, the model of quantum wireless wide-area networks is presented. In terms of time complexity, the proposed scheme transports a quantum bit in the time almost the same as the quantum teleportation regardless of the number of hops between the source and destination node. From this point of view, the quantum routing scheme is close to optimal scheme in data transmission time. The correlative routing process is proposed under different conditions. The quantum state is transferred by multistage quantum teleportation, therefore, the information transfer between any two nodes in quantum wireless wide-area networks is realized.
