Upcoming

Quantum Monte Carlo for Rydberg Arrays
Ejaaz merali, University of Waterloo
Wednesday, 2/12/2025, 12:00-1:00pm Pacific

Abstract: Arrays of Rydberg atoms, arranged into a programmable 2D lattice using optical tweezers, are a powerful platform to realize strongly-interacting quantum many-body systems. Classically simulating such systems is useful both for verifying experimental results, and for probing the physics of larger systems which may not yet be available experimentally. In this talk, I will discuss our recent quantum Monte Carlo (QMC) algorithm for exact simulations of Rydberg arrays in which we devise updates that allow for the efficient estimation of physical observables for typical experimental parameters. I will then move on to discussing applications of the data we generated using these simulations, including accelerating variational Monte Carlo by pre-training on QMC data, and training RydbergGPT, a generative pre-trained transformer which we trained on data from many points from the Rydberg phase diagram.

Bio: Ejaaz is a PhD candidate at the University of Waterloo interested in using Monte Carlo methods to simulate Quantum Many-Body systems on classical computers and leveraging Machine Learning techniques to accelerate these simulations.
