Minimal assumption derivation of a Bell-type inequality
Gerd Grasshoff, Samuel Portmann, Adrian Wuethrich
John Bell showed that a big class of local hidden-variable models stands in conflict with quantum mechanics and experiment. Recently, there were suggestions that empirical adequate…
Classical simulation of entanglement swapping with bounded communication
Cyril Branciard, Nicolas Brunner, Harry Buhrman +5
Entanglement appears under two different forms in quantum theory, namely as a property of states of joint systems and as a property of measurement eigenstates in joint measurements…
Minimal Assumption Derivation of a weak Clauser-Horne Inequality
Samuel Portmann, Adrian Wuethrich
According to Bell's theorem a large class of hidden-variable models obeying Bell's notion of local causality conflict with the predictions of quantum mechanics. Recently, a Bell-ty…
The local content of all pure two-qubit states
Samuel Portmann, Cyril Branciard, Nicolas Gisin
The (non-)local content in the sense of Elitzur, Popescu, and Rohrlich (EPR2) [Phys. Lett. A 162, 25 (1992)] is a natural measure for the (non-)locality of quantum states. Its comp…
