DQI Thesis Award Session: Learning in the Quantum Universe

ORAL ยท Invited

Abstract

In this talk, I will present my Ph.D. thesis on building a rigorous theory to understand how scientists, machines, and future quantum computers could learn models of our quantum universe. I will begin with an experimentally feasible procedure for converting a quantum many-body system into a succinct classical description of the system, its classical shadow. Classical shadows can be applied to efficiently predict many properties of interest, including expectation values of local observables and few-body correlation functions. I will then build on the classical shadow formalism to answer two fundamental questions at the intersection of machine learning and quantum physics: Can classical machines learn to solve challenging problems in quantum physics? And can quantum machines learn exponentially faster and predict more accurately than classical machines? The talk will answer both questions positively through mathematical analysis and experimental demonstrations.
