Determined Key Distribution Protocol Using Non-Orthogonal Quantum States

Abstract:

In this paper we provide an quantum determined key distribution protocol using non-orthogonal quantum states. Two parts can build a key by exchanging some qubits. The principles of quantum mechanics guarantee that the protocol is unconditionally secure. No one except the two parts can get the key. 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.
