The exclusivity principle: The fundamental theorem of quantum mechanics?

ABSTRACT — John Bell was the first to provide a proof of the impossibility of local hidden-variable models in quantum mechanics. Quantum theory predicts stronger correlations then the classical ones and this leads to violation of Bell inequalities.  On the other hand, quantum systems do not reach the algebraic maximum violation values.
The Exclusivity (E) principle states that the sum of the probabilities of a set of pairwise exclusive events cannot exceed 1. The E principle cannot be derived from Kolmogorov’s axioms. Recently, it has been shown that E principle can used to derive maximum violation bounds of certain Bell type inequalities.  Since the E principle excludes any set of correlations strictly larger than the quantum set, it might be the fundamental theorem of quantum mechanics in the sense that it can be used to reproduce quantum statistics. A century after its birth, we might be at the dawn of physical understanding of quantum theory.
