Constructing a theory of quantum gravity, and with it a notion of quantum spacetime is one of the biggest challenges faced by modern theoretical physics. This workshop will bring together researchers from a wide range of viewpoints and give them an opportunity to exchange ideas and gain new insights.

The workshop is supported by the Simons Foundation.

Recent 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.

Join us for a pioneering joint workshop between renowned research institutions in Munich and Waterloo! This exciting event will focus on the topic of quantum simulation, with additional talks delving into various subjects of quantum science and technology. Designed to include researchers across different levels, from group leaders, postdoctoral fellows, and PhD students, this inaugural collaboration aims to unite scientists from both locations, fostering valuable networking opportunities and promoting interdisciplinary collaboration. Don't miss this extraordinary opportunity to connect, exchange ideas, and shape the future of quantum research together! 
 

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

The annual Graduate Students’ Conference showcases the diverse research directions at Perimeter Institute, both organized and presented by the students. Our graduate students are invited to share their best work with their fellow PhD students, PSI students and other PI residents interested in hearing about physics research and discussing it in a lively atmosphere full of questions.

PSI students are welcome to join as audience members on Friday, Sept 13 and to present a Lightning Talk if they wish to do so.

Perimeter Institute is happy to host the inaugural summer school for the Simons Collaboration on Celestial Holography July 22-26 in Waterloo, ON. The program will feature lectures on background material relevant for graduate students and postdocs interested in this emerging subfield, paired with vision talks on exciting future research directions.

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.

The Perimeter Scholars International (PSI) Master's program is offered in collaboration by Perimeter Institute and the University of Waterloo.

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.

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.
