Study Of The Wireless Communication Network Based On The Quantum Teleportation

Quantum information is a combination of classic informatics and quantummechanics, it provides new principles and methods for information science andcommunications technology continuously. At present, the main researches of quantuminformation are quantum communication, quantum computation and quantumcryptography. Quantum communication mainly includes quantum teleportation,quantum key distribution and quantum dense coding. Quantum teleportation, aimportant research interests of quantum communication, is widely used in all fields ofcommunication. Using the instantaneity and security of the quantum transmission tobuilt a global quantum communication network has been a research hot topics.In this paper, the related knowledge of quantum communication and wirelesscommunication network are introduced firstly. Then, the information transmissionproblem and authentication problem are studied respectively based on quantumteleportation. Moreover,“Multistage quantum network wireless transmission” and“Identification scheme based on quantum teleportation for wireless communicationnetworks” are proposed respectively.1．The atmosphere is full of noise and interference, therefore long-distancequantum communication has been a problem in free space. Although there are somesolutions yet, they are just for systems which only contain one relay point. In themultistage quantum network wireless transmission scheme, the systems which containtwo relay points are discussed and the information transmission problem of this systemhas been solved. In addition, systems with N relay points are studied and the problem ofquantum information transmission over long distances can be solved.2．In the identification scheme based on quantum teleportation for wirelesscommunication networks, a concept of infrastructure quantum communication networkis proposed and an identification scheme for wireless communication networks isrealized by combining classical certification and quantum teleportation. Thisidentification scheme is discussed through the wireless LAN authentication andextended to the entire wireless communication network. In the wireless local areanetwork, the information is transmitted between STA and AP who had obtained the SKand EPR pair via quantum channel. Then AP will get the information through unitarytransformation and calculate the fidelity with the original backup information, so as todetermine whether the identification is successful or not.
