Decoy-state quantum key distribution with large random errors of light intensity

Xiang-Bin Wang
We show how to do decoy-state quantum key distribution efficiently with large random errors in the intensity control. We present a theorem for efficiently calculating the lower bound of single-photon counts with many undetermined parameters. In the calculation of the single-photon counts of our prot ... [Phys. Rev.
