Information Delay Protocol Using Non-Orthogonal Quantum States

Article Preview

In this paper we provide an information delay protocol using non-orthogonal quantum states. One person can send 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 sender decides to let the other get the information, he or she need only to send the latter some dictates through a public classical channel. There are no entangled states and complex quantum operations except measurements needed in our protocol. So it is easier to carry out and more robust in practice.
