基于五粒子团簇态实现四粒子团簇态的概率隐形传态
Probabilistic teleportation of four particle cluster state via five particle cluster state
摘要
Abstract
In order to realize the more economical probability teleportation of four particle cluster state,a teleportation scheme using five particle cluster state as quantum channel is proposed.Based on the disentanglement-teleportation-reconstruction method,the sender does a CNOT operation and projection measurement on information state before sending information.The disentanglement information is sent to the receiver.In this process,the sender needs to carry out two Bell state and single particle measurements.The receiver carries out the corresponding operation according to the sender's measurement results,and the entanglement information state is obtained.The original unknown information state is reconstructed by introducing auxiliary particle,and the probability of information successful transmission is 4|a|2.The scheme can be a good way to deal with the general eavesdropping.关键词
