The resource theory of causal influence and knowledge of causal influence
Marina Maciel Ansanelli, Beata Zjawin, David Schmid +5
Understanding and quantifying causal relationships between variables is essential for reasoning about the physical world. In this work, we develop a resource-theoretic framework to…
Distinguishability of causal structures under latent confounding and selection
Ryan Carey, Marina Maciel Ansanelli, Elie Wolfe +1
Statistical relationships in observed data can arise for several different reasons: the observed variables may be causally related, they may share a latent common cause, or there m…
On whether quantum theory needs complex numbers: the foil theories perspective
Yìlè Yīng, Maria Ciudad Alañón, Daniel Centeno +5
Recent work by Renou et al. (2021) has led to some controversy concerning the question of whether quantum theory requires complex numbers for its formulation. We promote the view t…
The Observational Partial Order of Causal Structures with Latent Variables
Marina Maciel Ansanelli, Elie Wolfe, Robert W. Spekkens
For two causal structures with the same set of visible variables, one is said to observationally dominate the other if the set of distributions over the visible variables realizabl…
