Quantum Determined Key Distribution Scheme Using Quantum Teleportation

Abstract

In this paper we provide a quantum determined key distribution protocol using quantum telportation. Unlike the previous protocols which produce a random string in the key distribution process as the key, in our protocol the two parties can share a predetermined binary string as the key with the help of quantum teleportation. The principles of quantum mechanics guarantees that no other people can get the key. So the protocol is unconditionally secure.
