Causalworlds 2026 - First Call for Papers

============================================

Causalworlds 2026: The 3rd International Conference on Quantum, Classical, and Relativistic Causality
Grenoble, France, June 22-26, 2026

Presentation and scope

============================================

Quantum mechanics has been a constant source of innovation for over a century, and is now opening the door to a new age of information technologies. Identifying the key quantum structures and developing new concepts and methods can accelerate the progress, facilitating the development of new information-processing protocols and the discovery of new connections with other areas of physics. This workshop brings together researchers working in quantum information science and in the foundations of quantum mechanics, with the aim of promoting cross-disciplinary interactions.

The Conference focuses on causality and non-locality in physics, and the insurgence of situations where it appears that causality can be violated, with emphasis on their relation with time machines. There are three main objectives before this conference:

Date/time: 20th November 2pm GMT/UTC
Speaker: Rob Spekkens (Perimeter Institute)
Title: Quantum correlations from the perspective of causal discovery algorithms

This is a rerun of Caslav Brukner's Q+ hangout that originally took place in July. Note the earlier than usual starting time.

Date: Tuesday 18th September
Time: 12noon British Summer Time
Speaker: Caslav Brukner (University of Vienna)
Title: Quantum correlations with indefinite causal order

Time: 2pm BST
Title: Quantum correlations with indefinite causal order

Abstract:

The conference focuses on causality and nonlocality in physics, with emphasis on its implications with time machines. In particular this issue will be dealt with from the viewpoints of General Relativity and Quantum Mechanics, two theories that, even though extensively verified on their own, are seemingly irreconcilable up today.
