Information Delay Protocol Using the Bell State Measurement

Abstract:

in this paper we present an information delay protocol using quantum the Bell state measurement. By sharing EPR(Einstain-Rosen-Podolsky) pairs and perform Control-NOT operation and the Bell state measurements, one person can give the other person some information which cannot be read until he or she lets the latter do. The unconditional security of the protocol is guaranteed by the laws of quantum physics. When the one decides to let the other 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.
