Dimensional reduction of the Dirac equation in arbitrary spatial dimensions
Davide Lonigro, Rocco Maggi, Giuliano Angelone +5
We investigate the general properties of the dimensional reduction of the Dirac theory, formulated in a Minkowski spacetime with an arbitrary number of spatial dimensions. This is…
Learning efficient decoders for quasi-chaotic quantum scramblers
Lorenzo Leone, Salvatore F. E. Oliviero, Seth Lloyd +1
Scrambling of quantum information is an important feature at the root of randomization and benchmarking protocols, the onset of quantum chaos, and black-hole physics. Unscrambling…
Unscrambling Quantum Information with Clifford decoders
Salvatore F. E. Oliviero, Lorenzo Leone, Seth Lloyd +1
Quantum information scrambling is a unitary process that destroys local correlations and spreads information throughout the system, effectively hiding it in nonlocal degrees of fre…
On the Bardeen-Cooper-Schrieffer interaction in quantum graphs
Francesco Romeo
We introduce a real-space version of the Bardeen-Cooper-Schrieffer interaction allowing the investigation of the non-trivial interplay between many-body physics and particles confi…
Dimensional reduction of the Dirac theory
Giuliano Angelone, Elisa Ercolessi, Paolo Facchi +5
We perform a reduction from three to two spatial dimensions of the physics of a spin-1/2 fermion coupled to the electromagnetic field, by applying Hadamard's method of descent. We…
Orbital angular momentum based intra- and inter- particle entangled states generated via a quantum dot source
Alessia Suprano, Danilo Zia, Mathias Pont +9
Engineering single-photon states endowed with Orbital Angular Momentum (OAM) is a powerful tool for quantum information photonic implementations. Indeed, thanks to its unbounded na…
Multiple scattering expansion for dielectric media: Casimir effect
Thorsten Emig, Giuseppe Bimonte
Recent measurements of Casimir forces have provided evidence of an intricate modification of quantum fluctuations of the electromagnetic field in complex geometries. Here we introd…
Optimizing quantum-enhanced Bayesian multiparameter estimation of phase and noise in practical sensors
Federico Belliardo, Valeria Cimini, Emanuele Polino +5
Achieving quantum-enhanced performances when measuring unknown quantities requires developing suitable methodologies for practical scenarios, that include noise and the availabilit…
Entanglement complexity of the Rokhsar-Kivelson-sign wavefunctions
Stefano Piemontese, Tommaso Roscilde, Alioscia Hamma
In this paper we study the transitions of entanglement complexity in an exemplary family of states - the Rokhsar-Kivelson-sign wavefunctions - whose degree of entanglement is contr…
Retrieving space-dependent polarization transformations via near-optimal quantum process tomography
Francesco Di Colandrea, Lorenzo Amato, Roberto Schiattarella +2
An optical waveplate rotating light polarization can be modeled as a single-qubit unitary operator, whose action can be experimentally determined via quantum process tomography. St…
Complexity of frustration: a new source of non-local non-stabilizerness
J. Odavić, T. Haug, G. Torre +3
We advance the characterization of complexity in quantum many-body systems by examining -states embedded in a spin chain. Such states show an amount of non-stabilizerness or "ma…
Qubit-oscillator relationships in the open quantum Rabi model: the role of dissipation
G. Di Bello, L. M. Cangemi, V. Cataudella +3
Using a dissipative quantum Rabi model, we study the dynamics of a slow qubit coupled to a fast quantum harmonic oscillator interacting with a bosonic bath from weak to strong and…
First-order transitions in spin chains coupled to quantum baths
C. A. Perroni, A. De Candia, V. Cataudella +2
We show that tailoring the dissipative environment allows to change the features of continuous quantum phase transitions and, even, induce first order transitions in ferromagnetic…
Squashed entanglement in one-dimensional quantum matter
Alfonso Maiellaro, Francesco Romeo, Roberta Citro +1
Squashed entanglement and its universal upper bound, the quantum conditional mutual information, are faithful measures of bipartite quantum correlations defined in terms of multipa…

Massimo Blasone, Silvio De Siena, Cristina Matrella
Using the wave-packet approach to neutrino oscillations, we analyze Quantum-Memory-Assisted Entropic Uncertainty Relations and show that uncertainty and the Non-local Advantage of…

Giampiero Esposito, Pietro Santorelli
This paper applies the Numerov and phase-integral methods to the stationary Schrodinger equation that studies bound states of charm anti-charm quarks. The former is a numerical met…
