Abstract:
The process matrix formalism allows us to go beyond the quantum circuit framework and study processes for which there may be no global causal order between events. While the notion of causal (non)separability has been well studied in the bipartite scenario, multipartite scenarios present a variety of new phenomena. In such scenarios, the definition of causal separability itself is subtle; I will discuss how it should be defined and show how such processes can be characterised

Biography:
Alastair Abbott did his PhD jointly between the University of Auckland and ENS Paris, working on quantum randomness and contextuality as an interdisciplinary thesis (part computer science, party physics, part philosophy). From 2015 he was in Grenoble with Cyril Branciard for 3 years, and since September he has been with Nicolas Brunner in Geneva.
