Gaussian state interferometry with passive and active elements
Carlo Sparaciari, Stefano Olivares, Matteo G. A. Paris
We address precision of optical interferometers fed by Gaussian states and involving passive and/or active elements, such as beam splitters, photodetectors and optical parametric a…
The Lindley paradox in optical interferometry
Camillo Mauri, Matteo G. A. Paris
The so-called Lindley paradox is a counterintuitive statistical effect where the Bayesian and frequentist approaches to hypothesis testing give radically different answers, dependi…
Information transmission over an amplitude damping channel with an arbitrary degree of memory
A. D'Arrigo, G. Benenti, G. Falci +1
We study the performance of a partially correlated amplitude damping channel acting on two qubits. We derive lower bounds for the single-shot classical capacity by studying two kin…
Verifying the quantumness of bipartite correlations
Claudio Carmeli, Teiko Heinosaari, Antti Karlsson +2
Entanglement is at the heart of most quantum information tasks, and therefore considerable effort has been made to find methods of deciding the entanglement content of a given bipa…
Non-Markovian continuous-time quantum walks on lattices with dynamical noise
Claudia Benedetti, Fabrizio Buscemi, Paolo Bordone +1
We address the dynamics of continuous-time quantum walks on one-dimensional disordered lattices inducing dynamical noise in the system. Noise is described as time-dependent fluctua…
Energy backflow and non-Markovian dynamics
Giacomo Guarnieri, Chikako Uchiyama, Bassano Vacchini
We explore the behavior in time of the energy exchange between a system of interest and its environment, together with its relationship to the non-Markovianity of the system dynami…
Continuous monitoring and the introduction of a classical level in Quantum Theory
G. M. Prosperi
In ordinary Quantum Mechanics only ideally instantaneous observations of a quantity or a set of compatible quantities are usually considered. In an old paper of our group in Milano…
Violation of Bell inequalities in larger Hilbert spaces: robustness and challenges
Werner Weiss, Giuliano Benenti, Giulio Casati +4
We explore the challenges posed by the violation of Bell-like inequalities by -dimensional systems exposed to imperfect state-preparation and measurement settings. We address, i…
Nonlinearity as a resource for nonclassicality in anharmonic systems
F. Albarelli, A. Ferraro, M. Paternostro +1
Nonclassicality is a key ingredient for quantum enhanced technologies and experiments involving macro- scopic quantum coherence. Considering various exactly-solvable quantum-oscill…
Non-Markovian dynamics in open quantum systems
Heinz-Peter Breuer, Elsi-Mari Laine, Jyrki Piilo +1
The dynamical behavior of open quantum systems plays a key role in many applications of quantum mechanics, examples ranging from fundamental problems, such as the environment-induc…
Full quantum state reconstruction of symmetric two-mode squeezed thermal states via spectral homodyne detection
Simone Cialdi, Carmen Porto, Daniele Cipriani +2
We suggest and demonstrate a scheme to reconstruct the symmetric two-mode squeezed thermal states of spectral sideband modes from an optical parametric oscillator. The method is ba…
Matter-wave interferometry: towards antimatter interferometers
Simone Sala, Fabrizio Castelli, Marco Giammarchi +2
Starting from an elementary model and refining it to take into account more realistic effects, we discuss the limitations and advantages of matter-wave interferometry in different…
How many orthonormal bases are needed to distinguish all pure quantum states?
Claudio Carmeli, Teiko Heinosaari, Jussi Schultz +1
We collect some recent results that together provide an almost complete answer to the question stated in the title. For the dimension d=2 the answer is three. For the dimensions d=…
Quantum Langevin equations for optomechanical systems
Alberto Barchielli, Bassano Vacchini
We provide a fully quantum description of a mechanical oscillator in the presence of thermal environmental noise by means of a quantum Langevin formulation based on quantum stochas…
Single- and two-mode quantumness at a beam splitter
Matteo Brunelli, Claudia Benedetti, Stefano Olivares +2
In the context of bipartite bosonic systems, two notions of classicality of correlations can be defined: P-classicality, based on the properties of the Glauber-Sudarshan P-function…
Two-mode squeezed vacuum and squeezed light in correlated interferometry
I. Ruo Berchera, I. P. Degiovanni, S. Olivares +3
We study in detail a system of two interferometers aimed to the detection of extremely faint phase-fluctuations. This system can represent a breakthrough for detecting a faint corr…
