Abstract:

Using the two times quantum teleportation, a quantum identification scheme of cross-center based on four-qubit cluster state is proposed, and the identification for user in distributed network is realized. In this scheme, the identification system consists of main server and client server, and the communication between main server and client server is performed using the four-qubit cluster state as quantum channel. All the operations of any user are processed at client server and there is no direct communication between user and main server. All authentications are processed by servers based on the principles of quantum mechanics, and its security is guaranteed by quantum mechanism. Finally, the security of the quamtum identification scheme is analysed.

Key words: quantum optics, quantum communication, quantum identification, quantum teleportation, cluster state
