基于非最大纠缠GHZ态的一种量子信息集中方案
Scheme of remote information concentration based on non-maximally entangled four-qubit GHZ state
摘要
Abstract
This paper proposed a scheme of remote information concentration via non-maximally entangled four-qubit GHZ state as quantum channel.Firstly,it constructed a whole system between an unknown cloning state and the quantum channel.Then,three separated parties performed Bell state measurement on their qubits respectively.After performing measurement,every one told the recuperator the measurement outcomes by classical information.Finally,the information was concentrated back to a single qubit with some appropriate measurements (projection measurement or POVM measurement).At the same time,this paper discussed the security and efficiency of the scheme and compared it with references[1,2] in detail.关键词
