BenchQC -- Scalable and modular benchmarking of industrial quantum computing applications
Florian Geissler, Eric Stopfer, Christian Ufrecht +19
We present BenchQC, a research project funded by the state of Bavaria, which promotes an application-centric perspective for benchmarking real-world quantum applications. Diverse u…
Digital quantum simulation of lattice gauge theories in three spatial dimensions
Julian Bender, Erez Zohar, Alessandro Farace +1
In the present work, we propose a scheme for digital formulation of lattice gauge theories with dynamical fermions in 3+1 dimensions. All interactions are obtained as a stroboscopi…
Versatile Gaussian probes for squeezing estimation
Luca Rigovacca, Alessandro Farace, Leonardo A. M. Souza +3
We consider an instance of black-box quantum metrology in the Gaussian framework, where we aim to estimate the amount of squeezing applied on an input probe, without previous knowl…
Digital lattice gauge theories
Erez Zohar, Alessandro Farace, Benni Reznik +1
We propose a general scheme for a digital construction of lattice gauge theories with dynamical fermions. In this method, the four-body interactions arising in models with di…
Digital quantum simulation of lattice gauge theories with dynamical fermionic matter
Erez Zohar, Alessandro Farace, Benni Reznik +1
We propose a scheme for digital quantum simulation of lattice gauge theories with dynamical fermions. Using a layered optical lattice with ancilla atoms that can move and interact…
Building versatile bipartite probes for quantum metrology
Alessandro Farace, Antonella De Pasquale, Gerardo Adesso +1
We consider bipartite systems as versatile probes for the estimation of transformations acting locally on one of the subsystems. We investigate what resources are required for the…
Gaussian Discriminating Strength
Luca Rigovacca, Alessandro Farace, Antonella De Pasquale +1
We present a quantifier of non-classical correlations for bipartite, multi-mode Gaussian states. It is derived from the Discriminating Strength measure, introduced for finite dimen…
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…
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…
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…
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…
Steady-state entanglement activation in optomechanical cavities
Alessandro Farace, Francesco Ciccarello, Rosario Fazio +1
Quantum discord, and a number of related indicators, are currently raising a relentless interest as a novel paradigm of non-classical correlations beyond entanglement. Beside merel…
Measures of quantum synchronization in continuous variable systems
A. Mari, A. Farace, N. Didier +2
We introduce and characterize two different measures which quantify the level of synchronization of interacting continuous variable quantum systems. The two measures allow to exten…
Enhancing Quantum Effects via Periodic Modulations in Optomechanical Systems
Alessandro Farace, Vittorio GIovannetti
Parametrically modulated optomechanical systems have been recently proposed as a simple and efficient setting for the quantum control of a micromechanical oscillator: relevant poss…
