 Bell’s results have been explored and deepened by various theoretical investigations and they have stimulated a number of increasingly sophisticated and delicate EPRB-type experiments designed to test whether the Bell inequalities hold where quantum theory predicts they should fail. With a few anomalous exceptions, the experiments appear to confirm the quantum violations of the inequalities. (Brunner et al 2014 is a comprehensive technical review.) The confirmation is quantitatively impressive, although not fully conclusive. There are a number of significant requirements on the experiments whose failures (generally downplayed as “loopholes”) allow for models of the experimental data that embody locality (in Bell’s sense), so-called local realist models. One family of “loopholes” (sampling) arises from possible losses (inefficiency) between emission and detection and from the delicate coincidence timing required to compute correlations. All the early experiments to test the Bell inequalities were subject to this loophole, so all could be modeled locally and realistically. (The prism and synchronization models in Fine 1982b are early models of this sort. Larsson 2014 is a general review.) Another “loophole” (locality) concerns whether Niels’ system, in one wing, could learn about what measurements are set to be performed in Albert’s wing in time to adjust its behavior. Experiments insuring locality need to separate the wings and this can allow losses or timing glitches that open them to models exploiting sampling error. Perversely, experiments to address sampling may require the wings to be fairly close together, close enough generally, it turns out, to allow information sharing and hence local realist models. There are now a few experiments that claim to close both loopholes together. They too have problems. (See Bednorz 2017 for a critical discussion.)
