Benchmarking quantum simulation at scale
Jeremy Hartse, Mohsin Raza, Shravan Shravan +2
The applications for which quantum computers will clearly outperform classical computers are still being identified and benchmarking such an advantage is challenging. We propose a…
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…
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…
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…
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…
