Independent Attacks in Imperfect Settings; A Case for A Two Way Quantum Key Distribution Scheme

arXiv:1009.3562 · doi:10.1016/j.physleta.2010.08.040

Abstract

We review the study on a two way quantum key distribution protocol given imperfect settings through a simple analysis of a toy model and show that it can outperform a BB84 setup. We provide the sufficient condition for this as a ratio of optimal intensities for the protocols.
