Quantum Information Transfer Between Energy Scales
Abstract
The broad aim of the Transfer of Quantum Information Between Energy Scales proposal is a detailed study of quantum operator dynamics in many-body systems, with a special focus on the way initially simple operators become increasingly complex as time passes. This operator dynamics translates directly into the transfer of quantum information from simple to complex degrees of freedom associated with different energy scales. Looking over the entire span of the project, we successfully developed and implemented several novel computation algorithms to compute operator dynamics at large size and long times. In this previously inaccessible regime, our tools led to the discovery of a new universal form of chaotic operator spreading and gave insights into the physics of localization. We have also taken the first steps to extend this work to consider the effects of quantum measurements and to connect to other manifestations of quantum chaos like hydrodynamics and random matrix universality.
