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…
Engineering Nonclassical States via the Dynamical Casimir Effect
Maristella Crotti, Luca Razzoli, Giacomo Guarnieri +3
Nonadiabatic driving in ultrastrongly coupled light--matter systems is commonly regarded as a source of errors, as counter-rotating interactions convert vacuum fluctuations into re…
Optimal control of a dissipative micromaser quantum battery in the ultrastrong coupling regime
Maristella Crotti, Luca Razzoli, Luigi Giannelli +2
We investigate the open-system dynamics of a micromaser quantum battery in the ultrastrong-coupling (USC) regime. The battery consists of a quantized harmonic mode sequentially int…
Optimal quantum transport on a ring via locally monitored chiral quantum walks
Sara Finocchiaro, Giovanni O. Luilli, Giuliano Benenti +2
In purely coherent transport on finite networks, destructive interference can significantly suppress transfer probabilities, which can only reach high values through careful fine-t…
Hybrid discrimination strategy in quantum communication based on photon-number-resolving detectors and mesoscopic twin-beam states
Luca Razzoli, Alex Pozzoli, Alessia Allevi
State discrimination is a key challenge in the implementation of quantum communication protocols. Most optical communication protocols rely on either coherent states of light or fr…
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:…
Synchronization-induced violation of thermodynamic uncertainty relations
Luca Razzoli, Matteo Carrega, Fabio Cavaliere +2
Fluctuations affect the functionality of nanodevices. Thermodynamic uncertainty relations (TURs), derived within the framework of stochastic thermodynamics, show that a minimal amo…
Efficient implementation of discrete-time quantum walks on quantum computers
Luca Razzoli, Gabriele Cenedese, Maria Bondani +1
Quantum walks have proven to be a universal model for quantum computation and to provide speed-up in certain quantum algorithms. The discrete-time quantum walk (DTQW) model, among…
Coin dimensionality as a resource in quantum metrology involving discrete-time quantum walks
Simone Cavazzoni, Luca Razzoli, Giovanni Ragazzi +2
We address metrological problems where the parameter of interest is encoded in the internal degree of freedom of a discrete-time quantum walker, and provide evidence that coin dime…
Dissipation-induced collective advantage of a quantum thermal machine
Matteo Carrega, Luca Razzoli, Paolo Andrea Erdman +3
Do quantum correlations lead to better performance with respect to several different systems working independently? For quantum thermal machines, the question is whether a working…

Luca Razzoli, Fabio Cavaliere, Matteo Carrega +2
In the quest for high-performance quantum thermal machines, looking for an optimal thermodynamic efficiency is only part of the issue. Indeed, at the level of quantum devices, fluc…

Quantum thermal machines can perform useful tasks, such as delivering power, cooling, or heating. In this work, we consider hybrid thermal machines, that can execute more than one…
Perturbed graphs achieve unit transport efficiency without environmental noise
Simone Cavazzoni, Luca Razzoli, Paolo Bordone +1
Coherent transport of an excitation through a network corresponds to continuous-time quantum walk on a graph, and the transport properties of the system may be radically different…

Luca Razzoli, Paolo Bordone, Matteo G. A. Paris
A fully connected vertex in a simple graph of order is a vertex connected to all the other vertices. Upon denoting by the Laplacian matrix of the graph, we pr…
