摘要： This paper presents a scheme for probabilistic remote preparation of a three-particle entangled Greenberger--Horne--Zeilinger (GHZ) state via three-particle orthonormal basis projective measurement, and then directly generalize the scheme to multi-particle case. It is shown that by using $N$ pairs of bipartite non-maximally entangled states as the quantum channel and $N$-particle orthonormal basis projective measurement, the multi-particle remote preparation can be successfully realized with a certain probability.
