Simple explanation of quantum nonlocality and contextuality
Considerable efforts have been devoted searching the principle that explains why some forms of Bell nonlocality and Kochen-Specker (KS) contextuality are possible and others are forbidden. Here, we show that the assumptions that statistically independent experiments exist and that every behavior that is not forbidden is compulsory, single out the same set of behaviors that quantum theory predicts for any Bell and KS contextuality scenario. As a byproduct, our result explains why the so-called almost quantum correlations for Bell scenarios are forbidden.
