Philosophy of Physics Graduate Lunch Seminar (Monday - Week 3, TT22)
Recent experiments claim to implement “indefinite causal order” – a phenomenon in which the direction of causal influence inherits some of the indeterminacy associated with superpositions of states. However, a study of the features of “quantum causal structures” reveals an interesting way of resisting this claim. In this talk, I’ll use these features to argue that indefinite causal order has only been realized in a weak sense. I’ll also discuss the significance of these causal features for interpreting quantum theory. This talk is a philosophical spin on a recent arxiv paper that develops the framework of “quantum causal models” https://arxiv.org/pdf/2204.10273.pdf.
