Abstract:
Recently, a new scheme for joint remotely preparing an arbitrary three-qubit state based on two three-qubit projective measurements was proposed. In this paper, we put forward two novel schemes to complete the joint remote preparation for this class of three-qubit state with complex coefficients via three Greenberger-Horne-Zeilinger (GHZ) states as the quantum channel. In the present schemes, two senders share the original state which they wish to help the receiver to remotely prepare. To complete the schemes, some novel sets of mutually orthogonal basis vectors are introduced. It is shown that, only if two senders collaborate with each other, and perform projective measurements under suitable measuring basis and appropriate unitary operations on their own qubits respectively, the receiver can reconstruct the original state. Compared with the previous scheme, the advantage of the present schemes is that the total success probability can reach 1.
