ResumoThis chapter aims to present a critical review of the problems related to the Einstein–Podolsky–Rosen (EPR) argumentation and to the Bell inequalities (BI). These problems have been considered mainly as being the completeness of quantum mechanics (QM) and QM nonlocality. From a compilation of existing correlation experiments, testing QM and the BIs, during the past decade, it may now be concluded almost with certainty that these BIs are violated and QM confirmed. If this is correct, then the crucial problem is to know how this evidence has to be interpreted, or to bring about its real significance. According to the present view, opinion has apparently settled that locality is responsible for the violation of the BI and is incompatible with the QM framework. Hence, QM, and any future theory with it, should be basically nonlocal. This conclusion originates certainly from the disproportion importance attributed to the hypotheses (H1) and (H3). As to the locality problem, nonlocality should be decided in single experiments such that the predictions depend in a clear way on whether locality is valid or not. The chapter presents the argument that the simplified EPR paradox could be avoided by assuming a breakdown of the CI of the QM state-vector reduction in the case of correlated systems when only one measuring device is present.
