Proposed optical test of Bell’s inequalities not resting upon the fair sampling assumption. (English) Zbl 1138.81341
Summary: Arguments are given against the fair sampling assumption, used to claim an empirical disproof of local realism. New tests are proposed, able to discriminate between quantum mechanics and a restricted, but appealing, family of local hidden-variables models. Such tests require detectors with efficiencies just above 20%.
