Understanding causality is fundamental to science and inspires wideranging applications, yet there are several distinct notions of causation. Recently, there have been important developments on the role of causality in quantum physics, relativistic physics and their interplay. These have unearthed a plethora of fascinating open questions regarding the nature of causation, emergence of spacetime structure and the limits of quantum information processing. At the same time, causal reasoning has become an important tool in machine learning and statistics, with applications ranging from big data to healthcare. This conference brings together experts from different areas of physics working on questions related to causality, as well as selected researchers who bridge the gap between fundamental research and current industrial applications. The aim of the conference is to provide a venue for crosspollination of these ideas through scientific exchange between these communities. The conference will focus on the following facets of causality:
• Quantum and classical causal inference
• Indefinite causal order and quantum reference frames
• Causality in quantum field theory and quantum gravity
• Experiments and applications of causality

Important datesPaper submission deadline: 24 May 2024 // 31 May 2024
Paper notification: 3 July 2024 Registration deadline (with application for financial assistance): 18 July 2024
Registration deadline: 28 August 2024
Conference: 1620 September 2024 Update: The submission deadline has been extended to 31st May 2024 for
papers which clearly justify their relevance for the following three
topics: 1) classical causal inference, 2) causality in relativistic physics (including quantum field theory and quantum gravity) and 3) experiments in causality. As we have received a sufficiently high number of submissions on the remaining topics (particularly indefinite causality and quantum causal models), the original deadline of 24th May still holds for submissions in this category. :: :: ::
Call for Abstracts
Prospective speakers can submit a paper for a contributed talk (in person or online) and/or a poster (in person only) via the Call for Abstracts. The Call for Abstracts is now open! Submissions for a talk will automatically be considered for a poster if not accepted for a talk.
