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…
Relating Wigner's Friend Scenarios to Nonclassical Causal Compatibility, Monogamy Relations, and Fine Tuning
Yìlè Yīng, Marina Maciel Ansanelli, Andrea Di Biagio +3
Nonclassical causal modeling was developed in order to explain violations of Bell inequalities while adhering to relativistic causal structure and faithfulness -- that is, avoiding…
Classifying Causal Structures: Ascertaining when Classical Correlations are Constrained by Inequalities
Shashaank Khanna, Marina Maciel Ansanelli, Matthew F. Pusey +1
The classical causal relations between a set of variables, some observed and some latent, can induce both equality constraints (typically conditional independences) as well as ineq…
