Accessible fragments of generalized probabilistic theories, cone equivalence, and applications to witnessing nonclassicality
John H. Selby, David Schmid, Elie Wolfe +3
The formalism of generalized probabilistic theories (GPTs) was originally developed as a way to characterize the landscape of conceivable physical theories. Thus, the GPT describin…
Restricted Hidden Cardinality Constraints in Causal Models
Beata Zjawin, Elie Wolfe, Robert W. Spekkens
Causal models with unobserved variables impose nontrivial constraints on the distributions over the observed variables. When a common cause of two variables is unobserved, it is im…
Entropic Inequality Constraints from -separation Relations in Directed Acyclic Graphs with Hidden Variables
Noam Finkelstein, Beata Zjawin, Elie Wolfe +2
Directed acyclic graphs (DAGs) with hidden variables are often used to characterize causal relations between variables in a system. When some variables are unobserved, DAGs imply a…
Contextuality without incompatibility
John H. Selby, David Schmid, Elie Wolfe +3
The existence of incompatible measurements is often believed to be a feature of quantum theory which signals its inconsistency with any classical worldview. To prove the failure of…
No Bipartite-Nonlocal Causal Theory Can Explain Nature's Correlations
Xavier Coiteux-Roy, Elie Wolfe, Marc-Olivier Renou
We show that some tripartite quantum correlations are inexplicable by any causal theory involving bipartite nonclassical common causes and unlimited shared randomness. This constit…
Any Physical Theory of Nature Must Be Boundlessly Multipartite Nonlocal
Xavier Coiteux-Roy, Elie Wolfe, Marc-Olivier Renou
We introduce the class of Genuinely Local Operation and Shared Randomness (LOSR) Multipartite Nonlocal correlations, that is, correlations between N parties that cannot be obtained…
Causal Networks and Freedom of Choice in Bell's Theorem
Rafael Chaves, George Moreno, Emanuele Polino +9
Bell's theorem is typically understood as the proof that quantum theory is incompatible with local-hidden-variable models. More generally, we can see the violation of a Bell inequa…
