Abstract

According to quantum mechanics,quantum communication has the advantages in information security than the classical communication,and so it has been studied as new hot spot in communication field.Mobile quantum communication is one of the most important parts in the future quantum communication.Quantum entanglement relay is one of the key technologies in mobile quantum communication systems.However,there are so many kinds of interference and noise in wireless channel,that it is very hard to realize the relay of the quantum states.To address and solve the problem,the two quanta relay schemes based on mobile terminals and base stations are presented firstly.The layered structure of wireless quantum communication and the routing protocol of the quantum states transmission in wireless(QMRP) are presented also.Theory analysis results show that the scheme above can transmit quanta states with no EPR pairs shared by source and objective nodes,and the time delay in transmission has nothing to do with the number of wireless hopping.It proves that the model and scheme are optimal.

A quantum routing scheme is proposed to teleport a quantum state from one quantum device to another wirelessly,even though the two devices do not share EPR pairs mutually.The scheme is based on entanglement swapping and quantum teleportation.The model of quantum wireless communication network and correlative communication protocol is presented.In order to be compatible with the conventional wireless communication network,the network architecture of a twotier database structure is proposed.In terms of qubit transmission time and security,performance analysis results show that the proposed scheme is superior to quantum relay routing scheme.The proposed scheme has high scalability and practicability.

Wireless quantum communication networks with mesh structure

Yang Cao, Xutao Yu, Youxun Cai

In distributed wireless quantum communication networks, because of the storage of the clients, the EPR pairs are important resources. The lack of EPR pairs limits the size of networks. Besides, to accomplish quantum teleportation, both classical and quantum information need to be transmitted. We may have difficulty in building classical and quantum channels at the same time. To solve these problems, we introduce mesh structure into wireless quantum communication. The distributed wireless quantum networks can be improved by this mesh structure we proposed. Moreover, a quantum routing protocol based on quantum relay mechanism is proposed in this mesh structure.

Quantum mobile communication is one of the hot-topics in the field of information, but entanglement signaling of quantum mobile communication radio interface transmission scheme is still a gap till now. Hence, this article firstly raises the concept of the Quantum Entanglement Signaling (QES) and frame structure of QES based on the conception. For the Quantum Mobile Terminal (QMT), this article studies the location registration, location update, and signaling processing and transmission scheme during the routing process. Then, the capacity between the Quantum Mobile Terminal (QMT) and the Quantum Mobile Base (QMB) in two-way communication is discussed. The results of the study indicate that quantum entanglement signaling transmission scheme and the capacity of radio interface proposed in this article can meet the needs of quantum mobile network for signaling transmission in the future.

Distributed wireless quantum communication networks

Xutao Yu, Jin S. Y. Xu, Zaichen Zhang

The distributed wireless quantum communication network (DWQCN) has a distributed network topology and transmits information by quantum states. In this paper, we present the concept of the DWQCN and propose a system scheme to transfer quantum states in the DWQCN. The system scheme for transmitting information between any two nodes in the DWQCN includes a routing protocol and a scheme for transferring quantum states. The routing protocol is on-demand and the routing metric is selected based on the number of entangled particle pairs. After setting up a route, quantum teleportation and entanglement swapping are used for transferring quantum states. Entanglement swapping is achieved along with the process of routing set up and the acknowledgment packet transmission. The measurement results of each entanglement swapping are piggybacked with route reply packets or acknowledgment packets. After entanglement swapping, a direct quantum link between source and destination is set up and quantum states are transferred by quantum teleportation. Adopting this scheme, the measurement results of entanglement swapping do not need to be transmitted specially, which decreases the wireless transmission cost and transmission delay.
