Causalworlds
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

Important dates
Paper 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: 16-20 September 2024 Update: The submission deadline has been extended to 31st May 2024 for

50 Years of Horndeski Gravity: Exploring Modified Gravity
Recent 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.
Presented by:
Sponsored in part by Gravity Theory Trust

• Modified Gravity Theories: Theoretical Framework and Models
• Tests of modified Gravity with Gravitational Waves (LIGO/LISA/PTA)
• Astrophysical/cosmological tests of gravity
• Mathematical structure of Modified gravity
• Observational tests of quantum gravity
• Modified gravity in the early universeConference Structure:
The conference will feature a balanced blend of plenary sessions (invited Speakers), contributed talks, panel discussions and poster presentations for students.
• Keynote presentations by renowned physicists in the field, discussing the impact of Horndeski theories and other modified theories of gravity on cosmology, dark energy, and black hole physics.
• Contributed talks: prioritizing early-career researchers
• Panel discussions on emerging research directions, unresolved questions, and potential applications of Horndeski theories.
• Poster sessions for early-career researchers and graduate students to showcase their work and receive feedback from senior scientists.:: :: ::

Physics of Quantum Information
The dialogue between quantum information and quantum matter has fostered notable progress in both fields. Quantum information science has revolutionized our understanding of the structure of quantum many-body systems and novel forms of out-of-equilibrium quantum dynamics. The advances of quantum matter have provided novel paradigms and platforms for quantum information processing.
This conference aims to bring together leading experts at the intersections of quantum information and quantum matter. Key topics include: (i) quantum error correction, (ii) quantum dynamics, and (iii) quantum simulation.Organizers:

Navigating Quantum and AI Career Trajectories: A Beginner’s Mini-Course on Computational Methods and their Applications
The 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.

SciComm Collider 2
The second annual SciComm Collider workshop will bring together a group of the most innovative science communicators helping to connect the public with topics in physics and astronomy for a three-day workshop aimed at sharing ideas, creating new collaborations, and exploring ways to more effectively engage the public with the most exciting ideas in science. The workshop will consist of short seminars, interactive sessions, and opportunities to brainstorm new ideas with fellow communicators and creators, as well as venues for interaction between invited science communicators and Perimeter outreach/communications team members and researchers.

Foundations of Quantum Computational Advantage
The 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:: :: ::
