Abstract :
In this paper we provide a multiparty information delay protocol using GHZ states. By sharing GHZ states one person can give the other two persons some information which cannot be read until he or she lets them do. The principles of quantum mechanics guarantee that the protocol is unconditionally secure. When the one decides to let the other two get the information, he or she need only to send some dictates through a public classical channel. So the protocol is easier to carry out and more robust in practice.
