Glassy dynamics with softened kinetic constraints on a noisy quantum computer
Marcel Cech, Igor Lesanovsky, Federico Carollo
Mid-circuit measurements provide direct access to trajectory-level observables, revealing dynamical structures in many-body systems that are invisible in ensemble-averaged quantiti…
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…
Large deviations and conditioned monitored quantum systems: a tensor network approach
MarÃa Cea, Marcel Cech, Federico Carollo +2
Coexistence of different dynamical phases is a hallmark of glassy dynamics. This is well-studied in classical systems where the underlying theoretical framework is that of large de…
From Classical Stochastic to Monitored Quantum Dynamics: Dynamical Phase Coexistence in East Circuit Models
Marcel Cech, Johan du Buisson, Cecilia De Fazio +2
Kinetically constrained models have been widely studied in the context of glass formers and non-equilibrium statistical mechanics. Although their simple local rules often result in…
Space-time correlations in monitored kinetically constrained discrete-time quantum dynamics
Marcel Cech, MarÃa Cea, Mari Carmen Bañuls +2
State-of-the-art quantum simulators permit local temporal control of interactions and midcircuit readout. These capabilities open the way towards the exploration of intriguing none…
Machine learning of quantum channels on NISQ devices
Giovanni Cemin, Marcel Cech, Erik Weiss +4
World-wide efforts aim at the realization of advanced quantum simulators and processors. However, despite the development of intricate hardware and pulse control systems, it may st…
