Abstract
We propose two novel schemes for remotely preparing a fourqubit clustertype entangled state FCES with complex coefficients by using four EPR pairs and two threequbit GHZ states as the quantum channel respectively To complete the remote state preparation RSP schemes several novel sets of fourand twoqubit measuring basis were introduced In these schemes after the sender performs two different projective measurements the receiver should introduce two auxiliary qubits and employ suitable CNOT gates on his qubits the original state can be reconstructed with unit successful probability Compared with the previous schemes for the RSP of a FCES the advantage of the present schemes is that the entanglement resource can be reduced
