Influence of the choice of postprocessing method on Bell inequalities

Mikołaj Czechlewski , Marcin Pawłowski

Abstract

In every experimental test of a Bell inequality, we are faced with the problem of inefficient detectors. How we treat the events when no particle is detected has a big influence on the properties of the test. In this work, we study this influence. We show that the choice of postprocessing can change the critical detection efficiency, the equivalence between different inequalities, or the applicability of the nonsignaling principle. We also consider the problem of choosing the optimal postprocessing strategy. We show that this is a nontrivial problem and that different strategies are optimal for different ranges of detector efficiencies.
