PLEASE NOTE: SUBMISSION DEADLINE EXTENDED FROM 24TH TO 31ST MAY ONLY FOR SPECIFIC TOPICS (SEE BELOW).

We are pleased to announce the conference, “Causalworlds 2024: The 2nd International Conference on Quantum, Classical, and Relativistic Causality” to be held at the Perimeter Institute, Waterloo, Ontario, Canada during 16-20 September 2024. We welcome submissions for contributed talks and posters, and this is a hybrid conference which is open to in-person as well as online participants. 

Conference website: www.causalworlds.ca

Understanding causality is fundamental to science and inspires wide-ranging 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 space-time 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 cross-pollination 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

Submission Guidelines

Prospective speakers can submit a paper for a talk and/or a poster. Submissions for a talk will automatically be considered for a poster if not accepted for a talk. 

We are now open for submissions:

* Talk: Submission will consist of (1) a 1-3 page summary, and (2) optionally a link to the full paper (published/preprint) or a draft of the manuscript. In the EasyChair submissions server, please enter a short abstract as plain text in the field "Abstract" and upload a pdf containing the 1-3 page summary of your submission along with the optional link to the full paper or draft of the manuscript (included in the same pdf file).

* Poster: Submission will consist of a short abstract, which can be directly entered as plain text in the field "Abstract" and no additional pdf needs to be uploaded in this case.

Important dates

• Paper submission deadline: 24 May 2024 (extended to 31 May for specific topics, see below)
• Paper notification: 3 July 2024 
• Registration deadline: late August 2024 
• Conference: 16-20 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.

All deadlines are in Anywhere on Earth time.
