Hi everyone,

Tomorrow morning we'll have a talk by Stefan Wolf entitled "from bell to boltzmann (via coiteux-roy)", and possibly also a second talk by Ämin Baumeler, title and abstract below. The time and place is 11:00 in D5.01, although we may start half an hour early at 10:30 if Ämin is going to speak as well. As usual I'll stream the talks online to our jitsi channel (https://meet.jit.si/CQISeminarTalks).

Hope to see you there,

Will

Title: Flow of dynamical causal structures

Abstract: Causal models capture cause-effect relations, offering a powerful tool for

analyzing and reasoning about processes. Recently, causal models were

successfully generalized to quantum processes, also to those with indefinite

causal order. In this talk I will present a tool---flow of causal structures---

to visualize and explore dynamical causal order in classical-deterministic

processes, like those seen in general relativity. As an application I will

show that if all leaf nodes of a flow are trivial, then the correlations must

decompose in a linear causal way.
