Quantum key distribution with combined conjugate coding and information overloading
Boris Skoric
Abstract
Most quantum key distribution schemes depend either on a form of conjugate coding or on the principle of putting more information into a quantum state than can possibly be read out with a measurement. We construct a scheme that combines both these approaches. It is built from Round-Robin Differential Phase Shift (RRDPS) and Unclonable Encryption. Compared to RRDPS and BB84-like protocols our scheme has the advantage that it thwarts simple attacks and forces the adversary to use entanglement. We provide a security analysis in case of attacks without entanglement. Part of this analysis also applies to the unmodified RRDPS.
Note: Mistakes corrected. Claims weakened.
