چکیده :

Using entanglement swapping, a quantum secret sharing protocol is proposed. After sharing three-EPR among users, for encoding the message, the sender prepares an auxiliary EPR pair and by operating defined Pauli operations, she transmits six-bit message to her two agents. Since using entanglement swapping, no qubits carrying message are transmitted. So, if the perfect quantum channel is used, the protocol is unconditional secure. In addition, this protocol enhances the efficiency of Zhang-Man and Chou et al. protocols and with the comparison of previous works has better performance.
