Catalytic Activation of Bell Nonlocality

Jessica Bavaresco, Nicolas Brunner, Antoine Girardin +2 more·Apr 2, 2025

The correlations of certain entangled states can be perfectly simulated classically via a local model. Hence such states are termed Bell local, as they cannot lead to Bell inequality violation. Here, we show that Bell nonlocality can nevertheless be ...
