Revealing emergent many-body phenomena by analyzing large-scale space-time records of monitored quantum systems
Marcel Cech, Cecilia De Fazio, MarÃa Cea +3
Recent advances in quantum simulators permit unitary evolution interspersed with locally resolved mid-circuit measurements. This paves the way for the observation of large-scale sp…
Reaction-diffusion dynamics of the weakly dissipative Fermi gas
Hannah Lehr, Igor Lesanovsky, Gabriele Perfetto
We study the one-dimensional Fermi gas subject to dissipative reactions. The dynamics is governed by the quantum master equation, where the Hamiltonian describes coherent motion of…
Parameter estimation with one- and two-time measurements on the emission field of the boundary time crystal
Albert Cabot, Federico Carollo, Igor Lesanovsky
Many-body quantum systems can exhibit collective effects that enhance the sensitivity of parameter estimation protocols. An example is provided by resonantly driven two-level atoms…
Detecting nonequilibrium phase transitions via continuous monitoring of space-time trajectories and autoencoder-based clustering
Erik Fitzner, Francesco Carnazza, Federico Carollo +1
The characterization of collective behavior and nonequilibrium phase transitions in quantum systems is typically rooted in the analysis of suitable system observables, so-called or…
Designing open quantum systems for enabling quantum enhanced sensing through classical measurements
Robert Mattes, Albert Cabot, Federico Carollo +1
Quantum systems in nonequilibrium conditions, where coherent many-body interactions compete with dissipative effects, can feature rich phase diagrams and emergent critical behavior…
Adiabatically driven dissipative many-body quantum spin systems
Paulo J. Paulino, Stefan Teufel, Federico Carollo +1
We explore the evolution of a strongly interacting dissipative quantum Ising spin chain that is driven by a slowly varying time-dependent transverse field. This system possesses an…
