Physics of Quantum Information
20 talksCollection Number C24017The 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 manybody systems and novel forms of outofequilibrium 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 MiniCourse on Computational Methods and their Applications
7 talksCollection Number C24029The dynamic field of quantum physics and artificial intelligence is expanding across both academic and industrial landscapes. This minicourse offers an introduction to computational techniques currently utilized in the quantum sector, highlighting nonacademic 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
3 talksCollection Number C24030The 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 threeday 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
21 talksCollection Number C24020The 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, nonclassicality, and quantum advantage
2. The complexity of classical simulation of quantum computation
3. The arithmetic of quantum circuits
4. The efficiency of faulttolerant quantum computation
Our view is that the future success of quantum computing critically depends on advances at the most fundamental level, and that largescale investments in quantum implementations will only pay off if they can draw on additional foundational insights and ideas:: :: ::

Strong Gravity 2023/24
13 talksCollection Number C24023This course will introduce some advanced topics in general relativity related to describing gravity in the strong field and dynamical regime. Topics covered include properties of spinning black holes, black hole thermodynamics and energy extraction, how to define horizons in a dynamical setting, formulations of the Einstein equations as constraint and evolution equations, and gravitational waves and how they are sourced. 
Mathematical Physics 2023/24
13 talksCollection Number C24026We will discuss mathematical aspects of classical and quantum field theory, including topics such as: symplectic manifolds and the phase space, symplectic reduction, geometric quantization, ChernSimons theory, and others. 
Quantum Gravity 2023/24
13 talksCollection Number C24024The course centers on an indepth study of the symmetry structure of General Relativity and how this is intimately related to its dynamics and to the challenges posed to its quantization. To achieve this understanding, we will introduce a host of concepts and techniques, broadly (and loosely) known under the name of “Covariant Phase Space Method”. This provides a different perspective on GR’s physics, a perspective in which phase space, rather than spacetime, is front and center. We will apply these ideas and techniques to discuss the socalled Problem of Time, Wald's approach to black hole entropy as a Noether charge, and the relationship between Dirac's Hypersurface Deformation Algebra and GR's symmetries and dynamics. We will also discuss the problem of detecting single gravitons as well as crucial analogies and differences between a quantum electromagnetic and gravitational field. Lecture notes specific for the course will be provided. 
Machine Learning 2023/24
12 talksCollection Number C24027Machine learning has become a very valuable toolbox for scientists including physicists. In this course, we will learn the basics of machine learning with an emphasis on applications for manybody physics. At the end of this course, you will be equipped with the necessary and preliminary tools for starting your own machine learning projects. 
String Theory 2023/24
13 talksCollection Number C24025The course covers the basics of String Theory: bosonic strings, Dbranes, a bit of superstrings.

GPTs and the probabilistic foundations of quantum theory  minicourse
7 talksCollection Number C24021Classical probability theory makes the (mostly, tacit) assumption that any two random experiments can be performed jointly. This assumption seems to fail in quantum theory. A rapidly growing literature seeks to understand QM by placing it in a much broader mathematical landscape of ``generalized probabilistic theories", or GPTs, in which incompatible experiments are permitted. Among other things, this effort has led to (i) a better appreciation that many "characteristically quantum" phenomena (e.g., entanglement) are in fact generic to nonclassical probabilistic theories, (ii) a suite of reconstructions of (mostly, finitedimensional) QM from small packages of assumptions of a probabilistic or operational nature, and (iii) a clearer view of the options available for generalizing QM. This course will offer a survey of this literature, starting from scratch and concluding with a discussion of recent developments.
Mathematical prerequisites: finitedimensional linear algebra, ideally including tensor products and duality, plus some exposure to category theory (though I will briefly review this material as needed).
Scheduling note: There will be 5 lectures from March 1226, then a gap of two weeks before the final 2 lectures held April 16 & 18.
Format: Inperson only; lectures will be recorded for PIRSA but not live on Zoom.

Quantum Field Theory for Cosmology (PHYS785/AMATH872)
24 talksCollection Number C24003This course introduces quantum field theory from scratch and then develops the theory of the quantum fluctuations of fields and particles. We will focus, in particular, on how quantum fields are affected by curvature and by spacetime horizons. This will lead us to the Unruh effect, Hawking radiation and to inflationary cosmology. Inflationary cosmology, which we will study in detail, is part of the current standard model of cosmology which holds that all structure in the universe  such as the distribution of galaxies  originated in tiny quantum fluctuations of a scalar field and of spacetime itself. For intuition, consider that quantum field fluctuations of significant amplitude normally occur only at very small length scales. Close to the big bang, during a brief initial period of nearly exponentially fast expansion (inflation), such smallwavelength but largeamplitude quantum fluctuations were stretched out to cosmological wavelengths. In this way, quantum fluctuations are thought to have seeded the observed inhomogeneities in the cosmic microwave background  which in turn seeded the condensation of hydrogen into galaxies and stars, all closely matching the increasingly accurate astronomical observations over recent years. The prerequisites for this course are a solid understanding of quantum theory and some basic knowledge of general relativity, such as FRW spacetimes.
