 One might want to conclude from the fact that quantum correlations are incompatible with the conjunction of faithfulness and the Markov condition that causal notions are inapplicable in the quantum realm. Yet we can experimentally interact with quantum systems and can intervene in and control such systems in ways that appear to be causal in similar ways to our interactions with classical physical systems. Moreover, as Sally Shrapnel (2014) has argued, there are macroscopic phenomena, such as the avian magneto-compass, that seem to require multi-level explanations that include quantum causal effects, which play an apparently causal, difference-making role. Efforts, such as Wood and Spekkens (2015) to try to develop causal representations of our interactions with quantum systems have led to the emergence of a research field devoted to extending the framework of structural causal models to quantum mechanics and to develop quantum causal models (Costa &amp; Shrapnel 2016; Allen et al. 2017; Shrapnel 2019). From the perspective of the three philosophical projects we distinguished above, these efforts are most naturally seen as engaging in the functional project of developing (and de novo engineering) causal concepts appropriate for the quantum realm and showing how such concepts can play a useful role in explanations and in capturing the ways in which we can manipulate and control quantum systems.
