Learning the Fine Structure of Quantum Dynamics in Programmable Quantum Matter

Rapid advances in analog quantum simulators and digital quantum computers have opened up novel ways to control and interrogate quantum many-body systems. Such capabilities allow for the exploration of previously inaccessible dynamical regimes–like dynamics in the presence of monitoring and feedback–as well as to furnish new tools to learn features of complex quantum states and processes. New questions arise as to the novel universal phenomena that can be found in these new dynamical regimes, and about the optimal strategies and fundamental limitations of extracting information from such quantum systems.

This program has three main goals: (i) to chart the landscape of quantum dynamics in programmable and interactive quantum matter, (ii) to identify fundamental and practical limits on learning from quantum experiments, and (iii) to apply these ideas toward long-standing foundational questions of statistical mechanics such as chaos, ergodicity, and thermalization. The program aims to make progress on these interdisciplinary research frontiers by bringing together the communities of quantum condensed matter physics, quantum information theory, statistical physics, and atomic-molecular-optical physics.
