Probabilistic Remote Preparation of a Three-ParticleEntangled State via Two Different Non-maximally EntangledChannels

Abstract

We present two schemes for preparing remotely athree-particle entangled state by two different quantum channels. In thefirst scheme, two partial three-particle entangled states are used as thequantum channels, while in the second scheme, three two-particlenon-maximally entangled states are employed as the quantum channels. It isshown that the remote state preparation can be successfully realized withcertain probability, for both two schemes, if a sender performs someprojective measurements and a receiver adopts some appropriate unitarytransformations. It is shown also that the successful probabilitiesof these two schemes are different.
