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…
Large deviations and conditioned monitored quantum systems: a tensor network approach
María 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…
Revealing emergent many-body phenomena by analyzing large-scale space-time records of monitored quantum systems
Marcel Cech, Cecilia De Fazio, María 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…
Space-time correlations in monitored kinetically constrained discrete-time quantum dynamics
Marcel Cech, María 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…
Pattern-based quantum functional testing
Erik Weiss, Marcel Cech, Stanislaw Soltan +4
With the growing number of qubits of quantum information processing devices, the task of fully characterizing these processors becomes increasingly unfeasible. From a practical per…
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…
Topological photon pumping in quantum optical systems
Mathias B. M. Svendsen, Marcel Cech, Max Schemmer +1
We establish the concept of topological pumping in one-dimensional systems with long-range couplings and apply it to the transport of a photon in quantum optical systems. In our th…
Dispersionless subradiant photon storage in one-dimensional emitter chains
Marcel Cech, Igor Lesanovsky, Beatriz Olmos
Atomic emitter ensembles couple collectively to the radiation field. Although an excitation on a single emitter may be short-lived, a collection of them can contain a photon severa…
Thermodynamics of quantum trajectories on a quantum computer
Marcel Cech, Igor Lesanovsky, Federico Carollo
Quantum computers have recently become available as noisy intermediate-scale quantum devices. Already these machines yield a useful environment for research on quantum systems and…
