The influence of the choice of post-processing method on Bell inequalities. (arXiv:1710.07082v1 [quant-ph])

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 was
detected has a big influence on the properties of the inequality. In this work,
we study this influence. We show that the choice of post-processing can change
the critical detection efficiency, the equivalence between different
inequalities or the applicability of the non-signaling principle. We also
consider the problem of choosing the optimal post-processing strategy. We show
that this is a non-trivial problem and that different strategies are optimal
for different ranges of detector efficiencies.
