Loss-and-Noise Tolerant Single-Shot Quantum Coin Flipping

Abstract

To make quantum coin flipping protocols more practical, we propose a new method that makes single-shot quantum coin flipping (SS-QCF) protocols tolerant of loss and noise. First, we present a new SS-QCF protocol which is a modification version of the previous one by Berlín et al.[ Phys. Rev. A Vol. 80 (2009), p. 062321]. Next, we prove that our protocol performs well against loss and noise. It shows that the presented protocol is able to be applied in real-world channels.
