Quantumness certification via non-demolition measurements
Paolo Solinas, Stefano Gherardini
The fundamental question of when a static or dynamic system should be deemed intrinsically quantum remains a challenge to address in absolute terms. In this regard, a critical requ…
Dynamical universality class for competing short- and long-range interactions
Jean-François de Kemmeter, Stefano Ruffo, Stefano Gherardini
Understanding the dynamical universality classes of systems with long-range interactions remains a key challenge in statistical physics. In this Letter, we analytically and numeric…
Conditioning in Generative Quantum Denoising Diffusion Models
Daniel Quinn, Lorenzo Buffoni, Stefano Gherardini +1
Quantum denoising diffusion models have recently emerged as a powerful framework for generative quantum machine learning. In this work, we extend these models by introducing a cond…
Impact of quantum coherence on the dynamics and thermodynamics of quenched free fermions coupled to a localized defect
Beatrice Donelli, Gabriele De Chiara, Francesco Scazza +1
We investigate the non-equilibrium quantum dynamics and thermodynamics of free fermions suddenly coupled to a localized defect in a one-dimensional harmonic trap. This setup realiz…
Orthogonalization speed-up from quantum coherence after a sudden quench
Beatrice Donelli, Gabriele De Chiara, Francesco Scazza +1
We introduce a nonequilibrium phenomenon, reminiscent of Anderson's orthogonality catastrophe (OC), that arises in the transient dynamics following an interaction quench between a…
Nonequilibrium thermometry via an ensemble of initially correlated qubits
Enrico Trombetti, Marco Malitesta, Marco Pezzutto +1
We investigate a nonequilibrium quantum thermometry protocol in which an ensemble of qubits, acting as temperature probes, is weakly coupled to a macroscopic thermal bath. The temp…
Non-positive energy quasidistributions in coherent collision models
Marco Pezzutto, Gabriele De Chiara, Stefano Gherardini
We determine the Kirkwood-Dirac quasiprobability (KDQ) distribution associated to the stochastic instances of internal energy variations for the quantum system and environment part…
Squeezing generation crossing a mean-field critical point: Work statistics, irreversibility and critical fingerprints
Fernando J. Gómez-Ruiz, Stefano Gherardini, Ricardo Puebla
Understanding the dynamical consequences of quantum phase transitions on thermodynamical quantities, such as work statistics and entropy production, is one of the most intriguing a…
