Bounding and simulating contextual correlations in quantum theory
Armin Tavakoli, Emmanuel Zambrini Cruzeiro, Roope Uola +1
We introduce a hierarchy of semidefinite relaxations of the set of quantum correlations in generalised contextuality scenarios. This constitutes a simple and versatile tool for bou…
Informationally restricted correlations: a general framework for classical and quantum systems
Armin Tavakoli, Emmanuel Zambrini Cruzeiro, Erik Woodhead +1
We introduce new methods and tools to study and characterise classical and quantum correlations emerging from prepare-and-measure experiments with informationally restricted commun…
Blind steering in no-signalling theories
Emmanuel Zambrini Cruzeiro, Nicolas Gisin, Sandu Popescu
Steering is a physical phenomenon which is not restricted to quantum theory, it is also present in more general, no-signalling theories. Here, we study steering from the point of v…
