摘      要：We propose an efficient method to create multipartite spin entangled states in quantum dots coupled to a nano electro-mechanical resonator *** method,based on the interaction between electron spins confined in quantum dots and the motion of magnetized nano electro-mechanical resonators,can enable a coherent spin-spin coupling over long distances and in principle be applied to an arbitrarily large number of electronic spins.
