Holographic generation of highly twisted electron beams
Vincenzo Grillo, Gian Carlo Gazzadi, Erfan Mafakheri +3
Free electrons can possess an intrinsic orbital angular momentum, similar to those in an electron cloud, upon free-space propagation. The wavefront corresponding to the electron's…
Mutual information as an order parameter for quantum synchronization
V. Ameri, M. Eghbali-Arani, A. Mari +4
Spontaneous synchronization is a fundamental phenomenon, important in many theoretical studies and applications. Recently this effect has been analyzed and observed in a number of…
Nonequilibrium fluctuations in quantum heat engines: Theory, example, and possible solid state experiments
Michele Campisi, Jukka Pekola, Rosario Fazio
We study the stochastic energetic exchanges in quantum heat engines. Due to microreversibility, these obey a fluctuation relation, called the heat engine fluctuation relation, whic…
Hamiltonian Purification
Davide Orsucci, Daniel Burgarth, Paolo Facchi +4
The problem of Hamiltonian purification introduced by Burgarth et al. [D. K. Burgarth et al., Nat. Commun. 5, 5173 (2014)] is formalized and discussed. Specifically, given a set of…
Heat flux dynamics in dissipative cascaded systems
Salvatore Lorenzo, Alessandro Farace, Francesco Ciccarello +2
We study the dynamics of heat flux in the thermalization process of a pair of identical quantum system that interact dissipatively with a reservoir in a {\it cascaded} fashion. Des…
Entanglement-Breaking Indices
Ludovico Lami, Vittorio Giovannetti
We study a set of new functionals (called entanglement--breaking indices) which characterize how many local iterations of a given (local) quantum channel are needed in order to com…
A Perturbative Approach to Continuous-Time Quantum Error Correction
Matteo Ippoliti, Leonardo Mazza, Matteo Rizzi +1
We present a novel discussion of the continuous-time quantum error correction introduced by Paz and Zurek in 1998 [Paz and Zurek, Proc. R. Soc. A 454, 355 (1998)]. We study the gen…
Shortcut to Adiabaticity in the Lipkin-Meshkov-Glick Model
Steve Campbell, Gabriele De Chiara, Mauro Paternostro +2
We study transitionless quantum driving in an infinite-range many-body system described by the Lipkin-Meshkov-Glick model. Despite the correlation length being always infinite the…
Spin entanglement in atoms and molecules
S. Pittalis, F. Troiani, C. A. Rozzi +1
We investigate the effects of inhomogeneities on spin entanglement in many-electron systems from an ab-initio approach. The key quantity in our approach is the local spin entanglem…
Analytical expression of Genuine Tripartite Quantum Discord for Symmetrical X-states
Andrea Beggi, Fabrizio Buscemi, Paolo Bordone
The study of classical and quantum correlations in bipartite and multipartite systems is crucial for the development of quantum information theory. Among the quantifiers adopted in…
The multi-mode quantum Entropy Power Inequality
Giacomo De Palma, Andrea Mari, Seth Lloyd +1
The quantum version of a fundamental entropic data-processing inequality is presented. It establishes a lower bound for the entropy that can be generated in the output channels of…
Quantum optomechanical piston engines powered by heat
Andrea Mari, Alessandro Farace, Vittorio Giovannetti
We study two different models of optomechanical systems where a temperature gradient between two radiation baths is exploited for inducing self-sustained coherent oscillations of a…
Waveguide-QED-based measurement of a reservoir spectral density
Francesco Ciccarello
The spectral density (SD) function has a central role in the study of open quantum systems (OQSs). We discover a method allowing for a "static" measurement of the SD - i.e., it req…
Majorization and additivity for multimode bosonic Gaussian channels
V. Giovannetti, A. S. Holevo, A. Mari
Recently, the longstanding Gaussian optimizer conjecture was proven for bosonic Gaussian gauge-covariant or contravariant channels in the work of Giovannetti, Holevo and Garcia-Pat…
Classical capacity of Gaussian thermal memory channels
Giacomo De Palma, Andrea Mari, Vittorio Giovannetti
The classical capacity of phase-invariant Gaussian channels has been recently determined under the assumption that such channels are memoryless. In this work we generalize this res…
Quantum Computing in Plato's Cave
Daniel Burgarth, Paolo Facchi, Vittorio Giovannetti +3
We show that mere observation of a quantum system can turn its dynamics from a very simple one into a universal quantum computation. This effect, which occurs if the system is regu…
Geometric quantum pumping in the presence of dissipation
Juzar Thingna, Peter Hänggi, Rosario Fazio +1
The charge transported when a quantum pump is adiabatically driven by time-dependent external forces in presence of dissipation is given by the line integral of a pumping field $\m…
Discriminating Strength: a bona fide measure of non-classical correlations
A. Farace, A. De Pasquale, L. Rigovacca +1
A new measure of non-classical correlations is introduced and characterized. It tests the ability of using a state ρ of a composite system AB as a probe for a quantum illumination…
A generalization of the Entropy Power Inequality to Bosonic Quantum Systems
Giacomo De Palma, Andrea Mari, Vittorio Giovannetti
In most communication schemes information is transmitted via travelling modes of electromagnetic radiation. These modes are unavoidably subject to environmental noise along any phy…
