Deterministic joint remote preparation of an arbitrary six-qubit cluster-type state

In this paper, we propose a feasible scheme for deterministic joint remote state preparation (JRSP) of an arbitrary six-qubit cluster-type state with the assistance of several GHZ entangled states and a two-qubit unitary operation. Firstly, Alice performs a two-qubit projective measurement according to the amplitude coefficients of the target state, and then Bob(1) and Bob(2) carries out other two projective measurements based on its phase coefficients. Next, a target two-qubit state is prepared with suitable operation. Finally, based on the arbitrary two-qubit state, the target six-qubit cluster-type state can be prepared by introducing four auxiliary particles and making appropriate local unitary operations with success probability 1. Furthermore, it's worth noting that our scheme is more security and feasible with the present technologies than most other previous schemes. (C) 2016 Elsevier GmbH. All rights reserved.
