Scheme for implementing perfect remote state preparation with W -class state in cavity QED
Wang Xue-Wen, Peng Zhao-Hui · Chinese Physics B · 2008
In this paper we present a remote state preparation scheme with a three-qubit W -class state in cavity QED. It has been shown that a special single-qubit state and a special two-qubit entangled state can be remotely prepared perfectly. Furthermore, the classical information cost in this scheme is less than that in the corresponding teleportation scheme and only a single-qubit projective measurement is made by the sender. We also generalize this idea to the multiqubit W -class state.
