Please Join us to celebrate Tommy Schuster and the completion of his PhD!

He will present a talk titled, “Many-body Quantum Information Dynamics.”

Abstract: Modern quantum experiments can realize large-scale phenomena that push the boundaries of both physics and computation. This has raised numerous questions: for instance, regarding what "many-body" quantum phenomena are possible, how they might be simulated via classical computers, and whether they can be detected in the presence of noise and limited experimental control. In this talk, I will show that the dynamics of quantum information provide a unifying perspective for answering some of these questions, drawing from works completed throughout my PhD. I will first introduce a framework based on quantum information dynamics to understand the propagation of noise in quantum simulators, which provides a potential theoretical underpinning to a line of experiments on the Loschmidt echo. I will then demonstrate how the same fundamental physics underlies a novel, many-body generalization of quantum teleportation, which has helped shed light on toy models of quantum gravity. Finally, I will discuss the necessity of time-reversed dynamics for experimentally measuring quantum information dynamics, as well as broader connections between this result and learning from quantum experiments.
