Probabilistic Remote Preparation of a Three-Particle Entangled State via Two Different Non-maximally Entangled Channels

摘要

＜正＞ We present two schemes for preparing remotely a three-particle entangled state by two different quantumchannels.In the first scheme,two partial three-particle entangled states are used as the quantum channels,while in thesecond scheme,three two-particle non-maximally entangled states are employed as the quantum channels.It is shownthat the remote state preparation can be successfully real/zeal with certain probability,for both two schemes,if a senderperforms some projective measurements and a receiver adopts some appropriate unitary transformations.It is shownalso that the successful probabilities of these two schemes are different.
