Abstract

We propose a new quantum key distribution (QKD) protocol, which exploits the maximal entanglement between home qubits and flying qubits induced by means of quantum Faraday rotation (QFR). The entanglement between the flying and home qubits provides the essential part of the security of the protocol. We also discuss possible experimental implementations, the optical cavity QED and quantum dots in microcavity, which is feasible in current spintronics technology.
