摘要
A quantum dialogue network is constructed, which uses GHZ states as quantum channel. As its application, a quantum dialogue protocol using entanglement swapping is presented. If the network is safe, any two users in the network can communicate under the control of the other users. (C) 2008 Elsevier B.V. All rights reserved.
