Entanglement and Classical Simulability in Quantum Extreme Learning Machines
A. De Lorenzis, M. P. Casado, N. Lo Gullo +3
Quantum Machine Learning (QML) has emerged as a promising framework for exploring how quantum dynamics may enhance data processing tasks. Here we investigate Quantum Extreme Learni…
Memory-Augmented Hybrid Quantum Reservoir Computing
J. Settino, L. Salatino, L. Mariani +9
Reservoir computing (RC) is an effective method for predicting chaotic systems by using a high-dimensional dynamic reservoir with fixed internal weights, while keeping the learning…
Bayesian mitigation of measurement errors in multiqubit experiments
F. Cosco, F. Plastina, N. Lo Gullo
In Phys. Rev. A 108, L060402 (2023), we introduced a Bayesian measurement error mitigation algorithm, which leveraged complete information from the readout signal, and validated th…
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…
Finite-time quantum Stirling heat engine
Sina Hamedani Raja, Sabrina Maniscalco, Gheorghe-Sorin Paraoanu +2
We study the thermodynamic performance of the finite-time non-regenerative Stirling cycle used as a quantum heat engine. We consider specifically the case in which the working subs…
Exact spectral function of a Tonks-Girardeau gas in a lattice
J. Settino, N. Lo Gullo, F. Plastina +1
The single-particle spectral function of a strongly correlated system is an essential ingredient to describe its dynamics and transport properties. We develop a general method to c…
Signatures of the single particle mobility edge in the ground state properties of Tonks-Girardeau and non-interacting Fermi gases in a bichromatic potential
J. Settino, N. Lo Gullo, A. Sindona +2
We explore the ground state properties of cold atomic gases, loaded into a bichromatic lattice, focusing on the cases of non-interacting fermions and hard-core (Tonks-Girardeau) bo…
Local Quench, Majorana Zero Modes, and Disturbance Propagation in the Ising chain
G. Francica, T. J. G. Apollaro, N. Lo Gullo +1
We study the generation and propagation of local perturbations in a quantum many-body spin system. In particular, we study the Ising model in transverse field in the presence of a…
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…
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…
Statistics of the work distribution for a quenched Fermi gas
A. Sindona, N. Lo Gullo, J. Goold +1
The local quench of a Fermi gas, giving rise to the Fermi edge singularity and the Anderson orthogonality catastrophe, is a rare example of an analytically tractable out of equilib…
Orthogonality catastrophe and decoherence in a trapped-Fermion environment
A. Sindona, J. Goold, N. Lo Gullo +2
The Fermi edge singularity and the Anderson orthogonality catastrophe describe the universal physics which occurs when a Fermi sea is locally quenched by the sudden switching of a…
