| Abstract: | We present a scheme for multiparty quantum remote secret conference(MQRSC) with pure entangled states, not maximally entangledmultipartite quantum systems. The conferees first share a privatequantum key, a sequence of pure entangled states and then use themto encode and decode the secret messages. The conferees exploit thedecoy-photon technique to ensure the security of the transmission ofqubits. This MQRSC scheme is more feasible and efficient thanothers. |
