Hi all,
Next week Antoine Coquet will talk about “Ruling out N-partite quantum causal networks as a complete theory of Nature”, see below for the abstract. The talk will take place on Monday at 16:00 in HIT E41.1.
Best, Ladina
*** Title:
Ruling out N-partite quantum causal networks as a complete theory of Nature
Abstract:
A fundamental pursuit of physics is to understand correlations between events, or, in other words, causal relationships. Causal networks are a useful conceptual tool to study such causal structures. In this talk, we will:
i) Give a brief introduction to the different types of correlations in Nature and to causal networks.
ii) Introduce the class of proof techniques called "proofs by inflation" alongside a novel instance of such proofs which was developed in the course of the present work.
iii) Use the above to prove that Nature’s correlations cannot be captured by quantum causal networks of N-partite quantum resources even when allowing for unlimited access to shared classical randomness.
