Collective decay of interacting bosons
Bennet Windt, Lorenzo Rossi, Alexander V. Poshakinskiy +2
We study a bosonic analog of the paradigmatic Dicke model of superradiance, comprising interacting bosonic modes subject to fully symmetric collective decay. Depending on the inter…
Magnetic domains stabilized by symmetry-protected zero modes
Pavel Kos, Dominik S. Wild, Kristian Knakkergaard Nielsen
Understanding mechanisms for the breakdown of thermalization in closed quantum systems is a central problem in quantum many-body physics. We demonstrate strong non-ergodic behavior…
Efficiently Learning Global Quantum Channels with Local Tomography
Zidu Liu, Dominik S. Wild
Scalable characterization of quantum processors is crucial for mitigating noise and imperfections. While randomized measurement protocols enable efficient access to local observabl…
Estimating ground-state properties in quantum simulators with global control
Cristian Tabares, Dominik S. Wild, J. Ignacio Cirac +3
Accurately determining ground-state properties of quantum many-body systems remains one of the major challenges of quantum simulation. In this work, we present a protocol for estim…
Hardware-efficient quantum phase estimation via local control
Benjamin F. Schiffer, Dominik S. Wild, Nishad Maskara +2
Quantum phase estimation plays a central role in quantum simulation as it enables the study of spectral properties of many-body quantum systems. Most variants of the phase estimati…
Quantum Simulation of Dynamical Response Functions of Equilibrium States
Esther Cruz, Dominik S. Wild, Mari Carmen Bañuls +1
The computation of dynamical response functions is central to many problems in condensed matter physics. Owing to the rapid growth of quantum correlations following a quench, class…
