Exact first-detection probability in a locally monitored solvable quantum circuit
Cecilia De Fazio, Igor Lesanovsky, Gabriele Perfetto
We study the interplay between local stroboscopic measurements and the unitary quantum circuit dynamics of the deterministic Floquet-quantum East model. We derive exact analytical…
Phase transitions in first-detection statistics of monitored long-range quantum walks
Sayan Roy, Shamik Gupta, Giovanna Morigi +1
In a quantum walk, the first-detection return probability (FDRP) characterizes salient features, determining whether the quantum walk is transient or recurrent. We study the FDRP o…
Nonequilibrium steady states induced by stochastic mid-circuit measurements and resets on a quantum computer
Jakob Murauer, Sabine Tornow, Gabriele Perfetto
Stochastic resetting has emerged as a versatile protocol to drive quantum many-body systems to non-equilibrium steady states by interspersing unitary dynamics with measurements and…
Towers of quantum many-body scars under stochastic resetting
Lorenzo Gotta, Manas Kulkarni, Gabriele Perfetto
Towers of quantum many-body scars are sets of highly-excited eigenstates of nonintegrable Hamiltonians whose dynamics shows athermal behavior and persistent oscillations in time. T…
Universal relaxation speedup in open quantum systems through transient conditional and unconditional resetting
Parvinder Solanki, Igor Lesanovsky, Gabriele Perfetto
Speeding up the relaxation dynamics of many-body quantum systems is important in a variety of contexts, including quantum computation and state preparation. We demonstrate that suc…
Nonanaliticities and ergodicity breaking in noninteracting many-body dynamics via stochastic resetting and global measurements
David Soldner, Igor Lesanovsky, Gabriele Perfetto
Stochastic resetting generates nonequilibrium steady states by interspersing unitary quantum dynamics with resets at random times. When the state to which the system is reset is ch…

Mario Boneberg, Simon Kochsiek, Gabriele Perfetto +1
In the vicinity of a phase transition ergodicity can be broken. Here, different initial many-body configurations evolve towards one of several fixed points, which are macroscopical…

At large scales of space and time, the nonequilibrium dynamics of local observables in extensive many-body systems is well described by hydrodynamics. At the Euler scale, one assum…
