[Abstract]:Quantum wireless multi-hop network is a kind of quantum communication network which is composed of a class of nodes with quantum communication and wireless communication ability. It is an extension of quantum communication network in the wireless field. Quantum teleportation and quantum wireless routing protocol are two essential technologies in quantum wireless multi-hop networks. However, existing quantum multi-hop teleportation methods are widely used in wireless communication. End-to-end transmission delay is large. Classical communication has many problems such as high overhead and low maximum probability of successful transmission. However, the existing quantum wireless routing protocols, such as routing metrics and quantum routing methods, also limit the performance of quantum teleportation. In this paper, quantum teleportation and quantum wireless routing protocols are deeply analyzed and studied, including parallel multi-hop teleportation and mapping of measurement results. Quantum path verification and other methods reduce the transmission delay and classical communication overhead. The quantum teleportation using two-particle and three-particle partially entangled states as the quantum channel improves the maximum success rate. Simulation results show that quantum wireless multi-hop network routing metrics and quantum wireless routing routing methods are suitable for the real situation. The main research work and innovation of this thesis are as follows:. 1. A multi-hop parallel low-delay teleportation method based on arbitrary Bell pairs is proposed. In order to achieve efficient quantum information transmission in quantum wireless multi-hop networks, parallel quantum entanglement switching technology is used to reduce end-to-end multi-hop transmission delay, and compared with serial entanglement switching method theoretically. This method has lower transmission delay and is suitable for more general network topologies. It also provides two methods of mathematical matrix calculation and finite state machine for the correct reduction of quantum states. Compared with exhaustive and charting methods, the complexity is reduced. 2. A result-mapping-based mapping method based on post-quantum measurement results is proposed. The measurement result mapping module solves the problem of the classical communication rising caused by sharing any kind of Bell pair in the classical information level. Compared with the method of pretransform Bell pair, it is easy to operate and can be implemented. At the same time, it adopts the technology of piggyback (piggyback) control information transmission in routing protocol packets. It is proved by theoretical analysis that this method reduces the classical communication overhead by 50. 3. A quantum channel transmission is proposed by means of two-particle partially entangled state and three-particle maximal entangled W state. The method of any two-particle entangled state. Through theoretical analysis, it is proved that the maximum probability of success of quantum teleportation is increased to 2 / 3. Compared with the method of using double W state as quantum channel, the maximum probability is 4 / 9). The maximum probability of successful transmission is increased by 50%, which is extended to the more general case, using the two-particle partially entangled state and the three-particle partially entangled GHZ state as the channel to realize the transmission of any two-particle state. It is proved by theoretical analysis that the maximum probability of successful quantum state transmission is 1.4. A quantum wireless source routing protocol based on path prior method is proposed to adapt to the parallel multi-hop transmission of quantum information in the network. Requirement. Through simulation test. It can improve the transmission success rate of the original routing protocol from 85% to 100, combining the parallel multi-hop teleportation method with the introduction of "prediction of classical communication hops" as a routing metric. The multi-hop quantum information transmission delay of 35% is reduced, and the simulation results show that the quantum mapping method can reduce the classical communication overhead of quantum teleportation.
