Are intrinsic decoherence models physical theories?
Maria Danelli, Matteo G. A. Paris
Intrinsic decoherence models (IDMs) have been proposed in order to solve the measurement problem in quantum mechanics. In this work, we assess the status of two of these models as…
Double-bracket quantum algorithms for high-fidelity ground state preparation
Matteo Robbiati, Edoardo Pedicillo, Andrea Pasquale +13
Ground state preparation is a central application for quantum computers but remains challenging in practice. In this work, we quantitatively investigate the performance and gate co…
Quantum noise modeling through Reinforcement Learning
Simone Bordoni, Andrea Papaluca, Piergiorgio Buttarini +3
In the current era of quantum computing, robust and efficient tools are essential to bridge the gap between simulations and quantum hardware execution. In this work, we introduce a…
Pseudomode treatment of strong-coupling quantum thermodynamics
Francesco Albarelli, Bassano Vacchini, Andrea Smirne
The treatment of quantum thermodynamic systems beyond weak coupling is of increasing relevance, yet extremely challenging. The evaluation of thermodynamic quantities in strong-coup…
Dynamical blockade of a reservoir for optimal performances of a quantum battery
F. Cavaliere, G. Gemme, G. Benenti +2
The development of fast and efficient quantum batteries is crucial for the prospects of quantum technologies. We show that both requirements are accomplished in the paradigmatic mo…
Quantum Entropies and Decoherence for the Multiparticle Quantum Arnol'd Cat

I study the scaling behavior in the physical parameters of dynamical entropies, classical and quantum, in a specifically devised model of collision-induced decoherence in a chaotic…
Behavior of correlation functions in the dynamics of the Multiparticle Quantum Arnol'd Cat
Giorgio Mantica
The multi-particle Arnol'd cat is a generalization of the Hamiltonian system, both classical and quantum, whose period evolution operator is the renown map that bears its name. It…
Assessing a binary quantum channel exploiting a Silicon photomultiplier based hybrid receiver
Alberto Sanvito, Silvia Cassina, Marco Lamperti +3
In quantum communication protocols, the use of photon-number-resolving detectors could open new perspectives by broadening the way to encode and decode information, and merging the…
Spectral Density Modulation and Universal Markovian Closure of Fermionic Environments

The combination of chain-mapping and tensor-network techniques provides a powerful tool for the numerically exact simulation of open quantum systems interacting with structured env…
Cyclic solid-state quantum battery: Thermodynamic characterization and quantum hardware simulation
Luca Razzoli, Giulia Gemme, Ilia Khomchenko +4
We introduce a cyclic quantum battery model, based on an interacting bipartite system, weakly coupled to a thermal bath. The working cycle of the battery consists of four strokes:…
Generalized phase estimation in noisy quantum gates
Giovanni Ragazzi, Simone Cavazzoni, Paolo Bordone +1
We examine metrological scenarios where the parameter of interest is encoded onto a quantum state through the action of a noisy quantum gate and investigate the ultimate bound to p…
