    "abstract": "We present two schemes for multiparty quantum remote secret conference in\nwhich each legitimate conferee can read out securely the secret message\nannounced by another one, but a vicious eavesdropper can get nothing about it.\nThe first one is based on the same key shared efficiently and securely by all\nthe parties with Greenberger-Horne-Zeilinger (GHZ) states, and each conferee\nsends his secret message to the others with one-time pad crypto-system. The\nother one is based on quantum encryption with a quantum key, a sequence of GHZ\nstates shared among all the conferees and used repeatedly after confirming\ntheir security. Both these schemes are optimal as their intrinsic efficiency\nfor qubits approaches the maximal value.",
