Locality and classicality: role of entropic inequalities
The use of the so-called entropic inequalities is revisited in the light of new quantum correlation measures, specially nonlocality. We introduce the concept of _classicality_ as the nonviolation of these classical inequalities by quantum states of several multiqubit systems and compare it with the nonviolation of Bell inequalities, that is, _locality_. We explore—numerically and analytically—the relationship between several other quantum ... Read more
