Quantum Information Delay Protocol Using Entanglement Swapping

Abstract:

In this paper we provide a quantum information delay protocol using entanglement swapping. By sharing Bell states 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 needs only to send some dictates through a public classical channel. So the protocol is easier to carry out and more robust in practice. On the other hand it can be more efficient and more secure than previous protocols.
