Complexity of Quantum Trajectories
Luca Lumia, Emanuele Tirrito, Mario Collura +2
Open quantum systems can be described by unraveling Lindblad master equations into ensembles of quantum trajectories. Here we investigate how the complexity of such trajectories is…
Emergence of Generic Entanglement Structure in Doped Matchgate Circuits
Alessio Paviglianiti, Luca Lumia, Emanuele Tirrito +4
Free fermionic Gaussian, a.k.a. matchgate, random circuits exhibit atypical behavior compared to generic interacting systems. They produce anomalously slow entanglement growth, cha…
Magic phase transitions in monitored gaussian fermions
Emanuele Tirrito, Luca Lumia, Alessio Paviglianiti +4
Monitored quantum systems, where unitary dynamics compete with continuous measurements, exhibit dynamical transitions as the measurement rate is varied. These reflect abrupt change…
Accuracy of time-dependent GGE under weak dissipation
Luca Lumia, Gianni Aupetit-Diallo, Jérôme Dubail +1
Unitary integrable models typically relax to a stationary Generalized Gibbs Ensemble (GGE), but in experimental realizations dissipation often breaks integrability. In this work, w…
Semiclassical Quantum Trajectories in the Monitored Lipkin-Meshkov-Glick Model
Alessandro Santini, Luca Lumia, Mario Collura +1
Monitored quantum system have sparked great interest in recent years due to the possibility of observing measurement-induced phase transitions (MIPTs) in the full-counting statisti…
Measurement-induced transitions beyond Gaussianity: a single particle description
Luca Lumia, Emanuele Tirrito, Rosario Fazio +1
Repeated measurements can induce entanglement phase transitions in the dynamics of quantum systems. Interacting models, both chaotic and integrable, generically show a stable volum…
Two-dimensional lattice gauge theory on a near-term quantum simulator: variational quantum optimization, confinement, and topological order
Luca Lumia, Pietro Torta, Glen B. Mbeng +4
We propose an implementation of a two-dimensional lattice gauge theory model on a shallow quantum circuit, involving a number of single and two-qubits gates comparab…
