Remote State Preparation with Genuine Multipartite Entanglement

Enlightened by the work of Yeo and Chua Phys. Rev. Lett. 96(2006)060502 for teleportation and dense coding with genuine multipartite entanglement, we present an explicit protocol for faithful remote state preparation in a real coefficient case by using the same four-particle entangled state which is not reducible to pair of Bell states. It is shown that any complex coefficient case can be changed to a real coefficient case. With this protocol, the state can play an analogous role to Einstein--Podolsky--Rosen pairs in the theory of multipartite entanglement.
