基于最大和非最大纠缠信道一类三量子比特W态的远程制备方案
Schemes for remotely preparing a class of three-qubit W states based on bipartite maximally and non-maximally entangled quantum channels
摘要
Abstract
Two schemes are put forward to remotely implement the preparation of a class of three-qubit W states,which employ maximally entangled states and non-maximally entangled states as the quantum channels,respectively.In the course of the preparations,some local quantum operations including threequbit projective measurements and unitary transformations are required.The success probability and classical information cost were worked out canoncally.The result shows that both schemes can be faithfully achieved in a probabilistic manner.Furthermore,the properties of the presented schemes were disscussed and their experimental feasibility was evaluated.It is found that the success probability can be doubled if the prepared states belong to some special ensembles,and the schemes can be well implemented with the current technologies.关键词
