Abstract: Entanglement between two separate systems is a necessary resource to violate a Bell inequality in a test of local realism. We demonstrate that to overcome the Bell bound, this correlation must be accompanied by the… read more here.

Abstract: At first sight, the use of an everywhere positive Wigner function as a probability density to perform stochastic simulations in quantum optics seems equivalent to the introduction of local hidden variables, thus preventing any violation… read more here.

DOI: 10.1126/sciadv.adr1794
Abstract: Violation of local realism via Bell inequality—a profound and counterintuitive manifestation of quantum theory that conflicts with the prediction of local realism—is viewed to be intimately linked with quantum entanglement. Experimental demonstrations of such a… read more here.
