Rapisarda's Experiment: Testing Quantum Mechanics versus Local Hidden-Variable Theories with Dichotomic Analyzers

Any decision about the validity of different physical theories can be taken only if it is possible to realize an experiment whose results can be directly compared with the different theoretical predictions. Owing to the lack of such an experimental check, the debate between the supporters of the orthodox formulation of the quantum mechanics (QM) and those who believed QM incomplete and therefore trusted in the possibility of completing it causally within a realistic vision of the physical world has been for a long time a comparison between ideologies rather than between different physical theories.
