【摘要】We investigate schemes for quantum secret sharing and quantum dense coding via tripartite entangled states.We present a scheme for sharing classical information via entanglement swapping using two tripartite entangled GHZ states. In order to throw light upon the security affairs of the quantum dense coding protocol, we also suggest a secure quantum dense coding scheme via W state by analogy with the theory of sharing information among involved users. 【总页数】4页(1421-1424)
