The Scrooge ensemble in many-body quantum systems
Max McGinley, Thomas Schuster
In many physical settings, the statistical properties of quantum states are thought to be described by the Scrooge ensemble, a more structured generalization of the Haar ensemble.…
Cooling the Sachdev-Ye-Kitaev model using thermofield double states
Thomas Schuster, Bryce Kobrin, Vincent P. Su +2
We analyze a simple and efficient experimental protocol to cool the Sachdev-Ye-Kitaev (SYK) model to low temperatures. The protocol utilizes local couplings between two copies of a…
Observation of ballistic plasma and memory in high-energy gauge theory dynamics
Daniel K. Mark, Federica M. Surace, Thomas Schuster +4
Gauge theories describe the fundamental forces of nature. However, high-energy dynamics, such as the formation of quark-gluon plasmas, is notoriously difficult to model with classi…
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…
A polynomial-time classical algorithm for noisy quantum circuits
Thomas Schuster, Chao Yin, Xun Gao +1
We provide a polynomial-time classical algorithm for noisy quantum circuits. The algorithm computes the expectation value of any observable for any circuit, with a small average er…
