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