The relevance of the preparation concept for the interpretation of Quantum formalism

Copyright © FrancoAngeli. There is an undefined notion in quantum theory, called the preparation procedure, which hasn't had the deserved relevance in quantum mechanical formalism's interpretation. Here we use the concepts of similar and identical preparation procedures to show the conceptual differences between the statistical and the conventional interpretation of quantum formalism. Although statistical understanding and its final logical consequence, hidden variables theories (this connexion being explained in the text), have great intuitive appeal due to its fewer ontological difficulties, both recent experimental results and theoretical developments seem to support a purely epistemic alternative closer to the conventional one. Nevertheless, we must not rule out the possibility that new no-go theorems may modify the dominance of this interpretation.
