Machine Learning for Quantum ManyBody Systems
Machine learning techniques are rapidly being adopted into the field of quantum manybody physics, including condensed matter theory, experiment, and quantum information science. The steady increase in data being produced by highlycontrolled quantum experiments brings the potential of machine learning algorithms to the forefront of scientific advancement. Particularly exciting is the prospect of using machine learning for the discovery and design of molecules, quantum materials, synthetic matter, and computers. In order to make progress, the field must address a number of fundamental questions related to the challenges of studying manybody quantum mechanics using classical computing algorithms and hardware.
The goal of this conference is to bring together experts in computational physics, machine learning, and quantum information, to make headway on a number of related topics, including:
 Datadrive quantum state reconstruction
 Machine learning strategies for quantum error correction and quantum control
 Neuralnetwork inspired wavefunctions
 Nearterm prospects for data from quantum devices
 Machine learning for quantum algorithm discovery

Quantum Simulators of Fundamental Physics
This meeting will bring together researchers from the quantum technology, atomic physics, and fundamental physics communities to discuss how quantum simulation can be used to gain new insight into the physics of black holes and the early Universe. The core program of the workshop is intended to deepen collaboration between the UKbased Quantum Simulators for Fundamental Physics (QSimFP; https://www.qsimfp.org) consortium and researchers at Perimeter Institute and neighbouring institutions. The weeklong conference will consist of broadlyaccessible talks on work within the consortium and work within the broader community of researchers interested in quantum simulation, as well as a poster session and ample time for discussion and collaboration

All sessions are available ONLINE except for those sessions in YELLOW blocks in the timeteable.
Research at the intersection of quantum physics and artificial intelligence is rapidly growing in academia and industry. This oneweek minicourse will introduce a selection of computational methods currently being applied in quantum industry settings and will highlight career opportunities outside of academia for students and researchers with a background in quantum theory and computational physics. The course will consist of two lecture series: one on generative modeling (including restricted Boltzmann machines, neural autoregressive distribution estimators, and recurrent neural networks) by Perimeter researchers Roger Melko and Mohamed Hibat Allah, and another lecture series on tensor networks and quantum algorithms by Martin Ganahl of SandboxAQ. Afternoons will include coding tutorials, workshops, talks from speakers who have transitioned from academia to quantum industry, and career networking opportunities.
Confirmed guests for the Industry networking session are:
 1QBit
 Agnostiq
 Amazon Web Services
 IBM Quantum
 Nord Quantique
 Quantum Valley Ideas Laboratories
 SandboxAQ
 Xanadu

 ZebraKet
This minicourse will assume that participants have the following prerequisites:

Graduatelevel knowledge of quantum mechanics (including wavefunctions, singlebody quantum mechanics, Hamiltonians, density matrices, time evolution, and angular momentum) and statistical mechanics (including partition functions, the Ising model, and phase transitions),

Knowledge of introductory machine learning methods (see, for instance, Lectures 16 of Perimeter’s course on Machine Learning for ManyBody Physics), and

Basic programming skills in Python.

Quantum Spacetime in the Cosmos: From Conception to Reality
On Demand Recording: https://pirsa.org/C23035
The nature of space and time is one of the most foundational mysteries in both Physics and Philosophy. At the heart of this mystery are the two most successful theories of nature: Einstein's theory of relativity, an elegant and precise description of the geometry of our universe on large scales, and Quantum Mechanics, outlining accurate laws of interaction in the subatomic world. But these two great triumphs of 20th century physics remain inherently inconsistent, contradictory in their most basic principles, such as locality and causality. Nonetheless, the experimental domains or natural phenomena where these contradictions become manifest have remained elusive, and it is not clear that a century of theoretical investigation into quantum gravity is anywhere close to being verified in nature.
Arguably, this disconnect is our greatest and most foundational challenge in the history of Physics; despite groundbreaking progress in both theory and observations of quantum spacetimes, these two endeavours are moving farther apart. Successfully responding to this centuryold challenge could require rethinking the epistemology of fundamental physics. While physicists are trained to push the frontiers of knowledge, developing a grand vision of the arch of history, and where we are (or should be) heading is a more interdisciplinary endeavor, requiring insights from theory and observations, but also philosophy and history.
We plan a focused, interactive, and highly interdisciplinary workshop, involving the world’s best theorists, observers, experimentalists, and philosophers, within a supportive, inclusive, and diverse environment, in order to kick start a long term initiative that might be our best bet to make significant progress towards uncovering the quantum nature of spacetime.Sponsorship provided by:

Quantum Matter (2022/2023)
Matter is quantum. Growing experimental results on materials, natural and synthetic (ion traps, cold atoms etc.,) and concomitant theoretical developments make `quantum matter' an exciting field. There is also a growing interplay of quantum matter physics and quantum information/computation. With a focus on concepts I plan to discuss key phenomenology, quantum models and theory. 
Mathematical Physics  Elective (2022/2023)
Title: An introduction to twistors Course Description: Twistor theory, introduced by Penrose many years ago, is a way to reformulate massless fields on fourdimensional spacetime in terms of an auxiliary 6dimensional complex manifold, called twistor space. This course will introduce twistor space and the Penrose correspondence (relating fields on twistor space and spacetime), at both classical and quantum levels. We will discuss the twistor realization of selfdual YangMills theory and of selfdual gravity. If time permits we will discuss the connection between twistors and celestial holography.

Quantum Gravity (2022/2023)
The main focus of this course is the exploration of the symmetry structure of General Relativity which is an essential step before any attempt at a (direct) quantization of GR. We will start by developing powerful tools for the analysis of local symmetries in physical theories (the covariant phase space method) and then apply it to increasingly complex theories: the parametrized particle, YangMills theory, and finally General Relativity. We will discover in which ways these theories have similar symmetry structures and in which ways GR is special. We will conclude by reviewing classical results on the uniqueness of GR given its symmetry structure and discuss why it is so hard to quantize it. In tutorials and homeworks, through the reading of articles and collegial discussions in the classroomas well as good old exercisesyou will explore questions such as "Should general relativity be quantized at all? Is a single graviton detactable (even in principle)?", "What is the meaning of the wave functions of the universe?", "Can we do physics without time?". 
Cosmology (2022/2023)
This class is an introduction to cosmology. We'll cover expansion history of the universe, thermal history, dark matter models, and as much cosmological perturbation theory as time permits. 
AdS/CFT (2022/2023)
We will cover the basics of the gauge/gravity duality, including some of the following aspects: holographic fluids, applications to condensed matter systems, entanglement entropy, and recent advances in understanding the black hole information paradox.
