Description
Bell's theorem states that quantum theory violates the principle of local-realism. It is known, however, that several nonlocal models cannot reproduce the entire range of quantum mechanical correlations either. What is it then that distinguishes quantum nonlocality from the nonlocality of other potential theories? In this talk we will see that quantum nonlocality is unique in that it stems from a very moderate dismissal of local-realism. In particular, we will present three conditions that together fully characterize local realistic theories. Any pair of the conditions together lead to the set of quantum mechanical correlations. Any of the conditions alone implies that the correlations are ``quantum-like''. And if all conditions are violated, the theory enables stronger-than-quantum correlations. The various implications of these results will be discussed.
