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…
