To do so, we consider the characterization of these quantum correlations as those of the form gamma = ( < u_i , v_j > )_{i,j=1}^n , where the vectors u_i and v_j are in the unit sphere of a real Hilbert space. The important parameters in this description are the number of vectors n and the dimension of the Hilbert space m. Thus, it is natural to study the probability of a quantum correlation being nonlocal as a function of alpha = m\/n , where the previous vectors are independent and uniformly distributed in the unit sphere of R^m. In this situation, our main result shows the existence of two completely different regimes: There exists an alpha_0 > 0 such that if alpha leq alpha_0, then gamma is nonlocal with probability tending to 1 as n rightarrow infty. On the other hand, if alpha geq 2 then gamma is local with probability tending to 1 as n rightarrow infty.","keywords":["nonlocality","quantum correlations","Bell inequalities","random matrices"],"author":[{"@type":"Person","name":"Gonz\u00e1lez-Guill\u00e9n, Carlos E.","givenName":"Carlos E.","familyName":"Gonz\u00e1lez-Guill\u00e9n"},{"@type":"Person","name":"Jim\u00e9nez, C.
