Information Delay Protocol Using Quantum Entangled States

Abstract:

In this paper we provide a information delay protocol using quantum entangled states. By sharing EPR(Einstain-Rosen-Podolsky) pairs one person can give the other person some information which cannot be read until he or she lets the latter do. The principles of quantum mechanics guarantee that the protocol is unconditionally secure. 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.
