An analysis on the almost quantum correlation set — •Vitor Sena and Rafael Rabelo — University of Campinas, Brazil

A good way to investigate the foundations of quantum theory is through the correlations it allows between results of measurements performed on spatially separated systems. These correlations may present some known nonclassical phenomena such as Bell nonlocality, but, interestingly, the set of nonlocal correlations allowed by quantum theory is quite specific and, in some sense, limited. There is a set of correlations slightly larger than this, known as the almost quantum correlations set, which presents similarities and differences with the set of quantum correlations. In this work, we study the relationship between these sets by numerically estimating their relative volumes in different scenarios. In doing so, we seek to understand the kind of correlations allowed by each one and how their differences can be shown quantitatively.
