Measurements conspire nonlocally to restructure critical quantum states
Samuel J. Garratt, Zack Weinstein, Ehud Altman
We study theoretically how local measurements perfomed on critical quantum ground states affect long-distance correlations. These states are highly entangled and feature algebraic…
Resonant energy scales and local observables in the many-body localised phase
Samuel J. Garratt, Sthitadhi Roy
We formulate a theory for resonances in the many-body localised (MBL) phase of disordered quantum spin chains in terms of local observables. A key result is to show that there are…
Quantifying information scrambling via Classical Shadow Tomography on Programmable Quantum Simulators
Max McGinley, Sebastian Leontica, Samuel J. Garratt +2
We develop techniques to probe the dynamics of quantum information, and implement them experimentally on an IBM superconducting quantum processor. Our protocols adapt shadow tomogr…
