Description
Abstract: In classical physics, any set of observables is
jointly measurable. In contrast, any graph in which nodes
represent observables and edges represent joint
measurability is realizable in quantum theory. Moreover,
correlations between quantum measurements violate some
Bell and noncontextuality inequalities satisfied by theories in
which observables are all jointly measurable. Remarkably,
quantum violations occur only for some inequalities and
only up to specific limits. Here we use a recently introduced
approach to answer three questions that are important to
understand quantum theory: (i) Which inequalities are
violated? (ii) Which violations are possible? (iii) Why?
