Floquet-engineered fidelity revivals in the PXP model
Francesco Perciavalle, Francesco Plastina, Nicola Lo Gullo
We explore the dynamics of the PXP model when subjected to a periodic drive, and unveil the mechanism through which the interplay between spectral properties and initial states gov…
Quantum Coherence and Anomalous Work Extraction in Qubit Gate Dynamics
Francesco Perciavalle, Nicola Lo Gullo, Francesco Plastina
We develop a framework based on the Kirkwood-Dirac quasiprobability distribution to quantify the contribution of coherence to work extraction during generic, cyclic quantum evoluti…
Speeding up Pontus-Mpemba effects via dynamical phase transitions
Andrea Nava, Reinhold Egger, Bidyut Dey +1
We demonstrate that open quantum systems exhibiting dynamical phase transitions (DPTs) allow for efficient protocols implementing the Pontus-Mpemba effect. The relaxation speed-up…
Predicting fermionic densities using a Projected Quantum Kernel method
Francesco Perciavalle, Francesco Plastina, Michele Pisarra +1
We use a support vector regressor based on a projected quantum kernel method to predict the density structure of 1D fermionic systems of interest in quantum chemistry and quantum m…
Harnessing Quantum Extreme Learning Machines for image classification
A. De Lorenzis, M. P. Casado, M. P. Estarellas +5
Interest in quantum machine learning is increasingly growing due to its potential to offer more efficient solutions for problems that are difficult to tackle with classical methods…
Variational Quantum Algorithms for the Allocation of Resources in a Cloud/Edge Architecture
Carlo Mastroianni, Francesco Plastina, Jacopo Settino +1
Modern Cloud/Edge architectures need to orchestrate multiple layers of heterogeneous computing nodes, including pervasive sensors/actuators, distributed Edge/Fog nodes, centralized…
Variational Gibbs State Preparation on NISQ devices
Mirko Consiglio, Jacopo Settino, Andrea Giordano +6
The preparation of an equilibrium thermal state of a quantum many-body system on noisy intermediate-scale quantum (NISQ) devices is an important task in order to extend the range o…
Enhancing qubit readout with Bayesian Learning
F. Cosco, N. Lo Gullo
We introduce an efficient and accurate readout measurement scheme for single and multi-qubit states. Our method uses Bayesian inference to build an assignment probability distribut…
A hybrid classical-quantum approach to speed-up Q-learning
A. Sannia, A. Giordano, N. Lo Gullo +2
We introduce a classical-quantum hybrid approach to computation, allowing for a quadratic performance improvement in the decision process of a learning agent. In particular, a quan…
Group theoretical derivation of consistent massless particle theories
Giuseppe Nisticò
Current theories of massless free particle assume {\sl unitary} space inversion and {\sl anti-unitary} time reversal operators. In so doing robust classes of possible theories are…
Mutual information for fermionic systems
Luca Lepori, Simone Paganelli, Fabio Franchini +1
We study the behavior of the mutual information (MI) in various quadratic fermionic chains, with and without pairing terms and both with short- and long-range hoppings. The models…
Universal scaling of a classical impurity in the quantum Ising chain
Tony J. G. Apollaro, Gianluca Francica, Domenico Giuliano +3
We study finite size scaling for the magnetic observables of an impurity residing at the endpoint of an open quantum Ising chain in a transverse magnetic field, realized by locally…
Quantum Otto cycle with inner friction: finite-time and disorder effects
A. Alecce, F. Galve, N. Lo Gullo +3
The concept of inner friction, by which a quantum heat engine is unable to follow adiabatically its strokes and thus dissipates useful energy, is illustrated in an exact physical m…
Transfer of arbitrary two qubit states via a spin chain
S. Lorenzo, T. J. G. Apollaro, S. Paganelli +2
We investigate the fidelity of the quantum state transfer (QST) of two qubits by means of an arbitrary spin-1/2 network, on a lattice of any dimensionality. Under the assumptions t…
Irreversible work and inner friction in quantum thermodynamic processes
F. Plastina, A. Alecce, T. J. G. Apollaro +5
We discuss the thermodynamics of closed quantum systems driven out of equilibrium by a change in a control parameter and undergoing a unitary process. We compare the work actually…
Global quantum correlations in finite-size spin chains
S. Campbell, L. Mazzola, G. De Chiara +4
We perform an extensive study of the properties of global quantum correlations in finite-size one-dimensional quantum spin models at finite temperature. By adopting a recently prop…
Discording power of quantum evolutions
F. Galve, F. Plastina, M. G. A. Paris +1
We introduce the discording power of a unitary transformation, which assesses its capability to produce quantum discord, and analyze in detail the generation of discord by relevant…
A logical analysis of Stapp's non-locality theorem
Giusepp Nisticò
According to an argument proposed by Stapp, Quantum Mechanics violates the Locality Principle if the two hypotheses of {\sl Free Choices} and {\sl No backward-in-time influence} ar…
