基于Cluster态的两粒子纠缠受控隐形传态

In order to teleport an unknown two-particle entangled state via a cluster state, a controlled teleportation scheme is proposed. It is shown that an unknown two-particle entangled state can be successfully transmitted from the sender Alice to the receiver Bob with the help of the supervisor Charlie via the only one four-particle cluster state. The receiver can reconstruct the teleported state according to the measurement results of the sender and supervisor. Quantum Controlled-NOT (CNOT) gate and POVM are used, which have been accomplished in a quantum experiment, so it is believed that this scheme will be realized by experiment. By analysis, the success probability of the proposed scheme reaches 1.0.

一种支持结构化P2P网络性能优化的双向克隆节点模型

In order to reduce the maintenance cost of structured Peer-to-Peer (P2P), Clone Node Protocol (CNP) based on user behavior is proposed. CNP considers the regularity of user behavior and uses the method of clone node. A Bidirectional Clone Node Chord model (BCNChord) based on CNP protocol is designed and realized. In BCNChord, Anticlockwise Searching Algorithm, Difference Push Synchronize Algorithm and Optimal Maintenance Algorithm are put forward to increase the performances. In experiments, according to the frequency of nodes, the maintenance cost of BCNChord can be 3.5% ~32.5% lower than that of Chord. In the network of 212 nodes, the logic path hop is steady at 6, which is much more prior to 12 of Chord and 10 of CNChord. Theoretical analysis and experimental results show that BCNChord can effectively reduce the maintenance cost of its structure and simultaneously improve the query efficiency up to (1/4)O (logN). BCNChord is more suitable for highly dynamic environment and higher real-time system.
