Puzzles in the Quantum Gravity Landscape: viewpoints from different approaches
Unraveling the quantum nature of gravity is one of the most pressing problems of theoretical physics. Several ideas have been put forward and resulted in a number of theories of quantum gravity. While these theories have explored different facets of the “quantum gravity landscape”, all viable approaches should ultimately make contact with observations, and answer exciting questions in cosmology and blackhole physics.
Sharing knowledge, exchanging ideas, and building a dictionary between different theories are crucial steps toward answering these questions, efficiently contrasting different theories, and ultimately reaching a deeper understanding of our Universe.
This conference will contribute to these goals by bringing together leading experts in different approaches to quantum gravity, gravitational effective field theory, blackhole physics, and cosmology. We will focus on specific puzzles in quantum gravity and their resolutions within different approaches. The conference will be highly interactive, with plenty of time to discuss common problems, understand the big picture, and develop novel connections between fields.Registration: Registration is now open, and both inperson and virtual participation is welcome. Online participants will be able to interact on an equal footing in question sessions and discussions. Inperson attendance is limited and will be approved on a firstcome, firstserved basis. Talks are by invitation only, but inperson participants are encouraged to apply to present a poster.

Perimeter Institute is located on the Haldimand Tract. After the American Revolution, the tract was granted by the British to the Six Nations of the Grand River and the Mississaugas of the Credit First Nation as compensation for their role in the war and for the loss of their traditional lands in upstate New York. Of the 950,000 acres granted to the Haudenosaunee, less than 5 percent remains Six Nations land. Only 6,100 acres remain Mississaugas of the Credit land.

Quantum Spectral Curve and Three Point Functions minicourse
In this minicourse we will describe some recent integrability developments in N=4 SYM. Pedro will start with some overview of three point functions in this theory. Paul will introduce the powerful Quantum Spectral Curve formalism describing the full planar spectrum of N=4 SYM starting with some elementary spin chain introduction. In this formalism, each operator in the theory is governed by a (set of) Qfunction(s). In his last lecture Paul will walk us through an explicit example from beginning to end of a QSC solution. Pedro will then describe some explorations on three point correlation functions in this theory. The goal would be to have a machine where three Qfunctions are given as input and a threepoint function is spit out as output. We will describe where we are in this quest.
No Zoom link or hybrid participation available. Registration is not required.



QPV 2023: Advances in quantum position verification
Quantum position verification (QPV) schemes use the properties of quantum information and the relativistic signalling bound to verify the location of an object (sometimes called a “tag”) to distant observers in an environment that may contain wouldbe spoofers. The guarantee is based on the assumptions of the underlying security model; various theoretically and practically interesting security models have been proposed. The area is attracting increasing interest, with new theoretical developments in security analyses, emerging experimental studies of QPV systems, and recently discovered surprising and intriguing connections to topics in quantum gravity. A workshop on QPV will be held at the Perimeter Institute for Theoretical Physics.
The workshop will cover topics related to all aspects of QPV, including, but not limited to:
 Theoretical developments related to the security of QPV schemes, including development or refinement of security models, proofs of security within given models, tradeoffs between security and efficiency, and Experimental studies of QPV and theoretical work aimed at developing practical QPV schemes.
 QPV’s relationship to other cryptographic tasks and primitives.
 QPV’s relationship to holography and quantum gravity.

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
