Benchmarking quantum simulation at scale
Jeremy Hartse, Mohsin Raza, Shravan Shravan +2
The paper introduces a scalable verification method for non‑equilibrium quantum simulations using stabilizer scars, enabling efficient fidelity estimation and providing a benchmark…
Stabilizer Scars
Jeremy Hartse, Lukasz Fidkowski, Niklas Mueller
Quantum many-body scars are eigenstates in non-integrable isolated quantum systems that defy typical thermalization paradigms, violating the eigenstate thermalization hypothesis an…
Entanglement Structure of Non-Gaussian States and How to Measure It
Henry Froland, Torsten V. Zache, Robert Ott +1
Rapidly growing capabilities of quantum simulators to probe quantum many-body phenomena require new methods to characterize increasingly complex states. We present a protocol that…
Quantum Computing Universal Thermalization Dynamics in a (2+1)D Lattice Gauge Theory
Niklas Mueller, Tianyi Wang, Or Katz +2
Simulating non-equilibrium phenomena in strongly-interacting quantum many-body systems, including thermalization, is a promising application of near-term and future quantum computa…
Quantum simulation of out-of-equilibrium dynamics in gauge theories
Jad C. Halimeh, Niklas Mueller, Johannes Knolle +2
Recent advances in quantum technologies have enabled quantum simulation of gauge theories -- some of the most fundamental frameworks of nature -- in regimes far from equilibrium, w…
Work and heat exchanged during sudden quenches of strongly coupled quantum systems
Zohreh Davoudi, Christopher Jarzynski, Niklas Mueller +3
How should one define thermodynamic quantities (internal energy, work, heat, etc.) for quantum systems coupled to their environments strongly? We examine three (classically equival…
