Discovering Quantum Causal Models

Abstract

Costa and Shrapnel ([2016]) have recently proposed an interventionist theory of quantum causation. The formalism generalizes the classical methods of Pearl ([2000]) and allows for the discovery of quantum causal structure via localized interventions. Classical causal structure is presented as a special case of this more general framework. I introduce the account and consider whether this formalism provides a causal explanation for the Bell correlations. 1 Introduction 2 Classical Causal Models 3 What's the (Quantum) Problem? 4 Quantum Causal Models: Why Bother? 5 Markov Quantum Causal Models 6 The Bell Experiment 7 Bell's Objections.
