A Universal Protocol for Quantum-Enhanced Sensing via Information Scrambling
Bryce Kobrin, Thomas Schuster, Maxwell Block +4
We introduce a novel protocol, which enables Heisenberg-limited quantum-enhanced sensing using the dynamics of any interacting many-body Hamiltonian. Our approach - dubbed butterfl…
Operator Growth in Open Quantum Systems
Thomas Schuster, Norman Y. Yao
The spreading of quantum information in closed systems, often termed scrambling, is a hallmark of many-body quantum dynamics. In open systems, scrambling competes with noise, error…
Information-theoretic Hardness of Out-of-time-order Correlators
Jordan Cotler, Thomas Schuster, Masoud Mohseni
We establish that there are properties of quantum many-body dynamics which are efficiently learnable if we are given access to out-of-time-order correlators (OTOCs), but which requ…
Learning quantum systems via out-of-time-order correlators
Thomas Schuster, Murphy Niu, Jordan Cotler +3
Learning the properties of dynamical quantum systems underlies applications ranging from nuclear magnetic resonance spectroscopy to quantum device characterization. A central chall…
