Macroscopic noncontextuality as a principle for almost-quantum correlations

Macroscopic noncontextuality as a principle for almost-quantum correlations

Quantum mechanics allows only certain sets of experimental results (or "probabilistic models") for Bell-type quantum non-locality experiments. A derivation of this set from simple physical or information theoretic principles would represent an important step forward in our understanding of quantum mechanics, and this problem has been intensely investigated in recent …
