However, Aerts et al. noted that Franson’s Bell-test is in-trinsically affected by the postselection loophole (PSL) [22], which is present independently to the other loopholes (eg., lo-cality and detection) that could affect local-realistic tests [23].

This was a simple … clopixol mechanism of actionAll three tests simultaneously addressed the detection loophole, the locality loophole, and the memory loophole. This makes them “loophole-free” in the sense that all remaining conceivable loopholes like superdeterminism require truly exotic hypotheses that might never get closed experimentally. Ver mais A Bell test, also known as Bell inequality test or Bell experiment, is a real-world physics experiment designed to test the theory of quantum mechanics in relation to Albert Einstein's concept of local realism.
