Classical Physics and the Bounds of Quantum Correlations
(American Physical Society, 2016-06-24)
A unifying principle explaining the numerical bounds of quantum correlations remains elusive, despite the efforts devoted to identifying it. Here, we show that these bounds are indeed not exclusive to quantum theory: for ...
