Energetic Cost of Temporal Information Processing in Quantum Reservoirs
Gabriele Cenedese, Gonzalo Manzano, Gian Luca Giorgi +1
Quantum reservoir computing offers a promising route toward energy-efficient machine learning by processing temporal information with minimal training overhead. Yet, the physical p…
Mesoscopic Quantum Communication via Photon-Number Moments
Gabriele Cenedese, Alex Pozzoli, Luca Razzoli +1
Mesoscopic optical states are a promising resource for quantum communication, combining robustness against losses with the preservation of genuine quantum features. Here, we propos…
-VQE: Excited-state preparation of quantum many-body scars with shallow circuits
Eoin Carolan, Nathan Keenan, Gabriele Cenedese +1
We present and benchmark a type of variational quantum eigensolver (VQE), which we denote -VQE. It is designed to target mid-spectrum eigenstates and prepare quantum many-body…
Boosting Work Extraction in Quantum Batteries via Continuous Environment Monitoring
Gabriele Cenedese, Giuliano Benenti, Dario Ferraro +1
During the charging process, interactions between a quantum battery and its charger generally generate quantum correlations, which may reduce the amount of work extractable from th…
Thermodynamics and Protection of Discrete-Time Crystals
Gabriele Cenedese, Samuel T. Mister, Mauro Antezza +2
Discrete-Time Crystals (DTC) are a non-equilibrium phase of matter characterized by the breaking of time-translation symmetry in periodically driven quantum systems. In this work,…
