Abstract
Cluster state is deemed to be a significant quantum resource, for it can encode much information; its remote preparation is significant to the quantum information processing. In the paper, a novel joint remote quantum state preparation protocol is proposed, in which three participants are included, and they are cooperatively involved for the protocol accomplishment within the configuration constructed by the four-qubit cluster type and EPR pairs. The cluster-type state is successful prepared via the appropriate unitary operations after the relevant participants perform the projection measurement. The presented protocol shows highly secure and could stand against the external eavesdropper.
