Future Prospects of Intensity Interferometry
24 talks-Collection NumberC24046Recent advancements in photodetection technologies and spectroscopy hold the promise of transforming intensity interferometry, thereby revolutionizing observational Astronomy by enabling observations to resolve significantly fainter objects than currently possible. This workshop serves as a platform to unite experts in photodetection, theoretical and observational astronomy, as well as observers and theorists from diverse disciplines, to explore the multifaceted capabilities of intensity interferometry.
The workshop's focus spans three key objectives:
- Develop and disseminate novel ideas concerning science cases unique to intensity interferometry.
- Synthesize insights from observers and photodetector experts concerning the requisite technologies and experimental techniques which will allow for new science with intensity interferometry.
- Initiate a concentrated effort to propel the development of large telescope arrays dedicated to intensity interferometry.
This workshop will be exclusively organized in plenary sessions, providing ample time for engaging discussions among participants.

Causalworlds
63 talks-Collection NumberC24018Understanding 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

50 Years of Horndeski Gravity: Exploring Modified Gravity
46 talks-Collection NumberC24019Recent years have seen a flood of new data, from gravitational wave observations of merging black holes and neutron stars to precision probes of cosmology, which allow for unprecedented tests of our understanding of gravity. Going hand-in-hand with this, there has been significant recent progress on the theoretical side in terms of formulating modified theories of gravity, and using them to make detailed predictions, including in the nonlinear and dynamical regime, which can be confronted with the observations.
We are excited to announce a landmark conference that plans to delve into the forefront of research on modified theories of gravity and brings together leading experts from different disciplines including observational astrophysicists, numerical relativists, cosmologists and mathematical physicists to explore the present status of modified theories of gravity and envision their future theoretical development and implications for observations.
This conference is also timed to coincide with the 50th anniversary of pioneering work in this area carried out by Gregory Horndeski in the Waterloo Mathematical Physics Community. Hosted jointly by Perimeter Institute and the University of Waterloo, this conference will serve as a forum for researchers from different disciplines to exchange ideas at the cutting
edge of gravitational physics.

Navigating Quantum and AI Career Trajectories: A Beginner’s Mini-Course on Computational Methods and their Applications
7 talks-Collection NumberC24029The dynamic field of quantum physics and artificial intelligence is expanding across both academic and industrial landscapes. This mini-course offers an introduction to computational techniques currently utilized in the quantum sector, highlighting non-academic career paths for individuals interested in quantum physics and machine learning. The program features two lecture series: one on generative modeling - covering topics (such as restricted Boltzmann machines, recurrent neural networks, and transformers) - and the other on quantum machine learning algorithms. Participants will also benefit from practical coding tutorials, networking opportunities, and related events about the landscape of Quantum and AI.

Foundations of Quantum Computational Advantage
21 talks-Collection NumberC24020The workshop marks the halfway point of the similarly named (FoQaCiA, pronounced "focaccia") collaboration between researchers in Canada and Europe, funded as part of a flagship partnership between NSERC and Horizon Europe.
https://www.foqacia.org/
The goal of FoQaCiA is to develop new foundational approaches to shed light on the relative computational power of quantum devices and classical computers, helping to find the "line in the sand" separating tasks admitting a quantum speedup from those that are classically simulable.
The workshop will focus on the four central interrelated themes of the project:
1. Quantum contextuality, non-classicality, and quantum advantage
2. The complexity of classical simulation of quantum computation
3. The arithmetic of quantum circuits
4. The efficiency of fault-tolerant quantum computation
Our view is that the future success of quantum computing critically depends on advances at the most fundamental level, and that large-scale investments in quantum implementations will only pay off if they can draw on additional foundational insights and ideas:: :: ::

Higher Categorical Tools for Quantum Phases of Matter
15 talks-Collection NumberC24016Quantum phases have become a staple of modern physics, thanks to their appearance in fields as diverse as condensed matter physics, quantum field theory, quantum information processing, and topology. The description of quantum phases of matter requires novel mathematical tools that lie beyond the old symmetry breaking perspective on phases. Techniques from topological field theory, homotopy theory, and (higher) category theory show great potential for advancing our understanding of the characterization and classification of quantum phases. The goal of this workshop is to bring together experts from across mathematics and physics to discuss recent breakthroughs in these mathematical tools and their application to physical problems.
