Abstract 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.
