Quantum correlations and limit cycles in the driven-dissipative Heisenberg lattice
E. T. Owen, J. Jin, D. Rossini +2
Driven-dissipative quantum many-body systems have attracted increasing interest in recent years as they lead to novel classes of quantum many-body phenomena. In particular, mean-fi…
Optimal thermodynamic control in open quantum systems
Vasco Cavina, Andrea Mari, Alberto Carlini +1
We apply advanced methods of control theory to open quantum systems and we determine finite-time processes which are optimal with respect to thermodynamic performances. General pro…
Interferometric modulation of quantum cascade interactions
Stefano Cusumano, Andrea Mari, Vittorio Giovannetti
We consider many-body quantum systems dissipatively coupled by a cascade network, i.e. a setup in which interactions are mediated by unidirectional environmental modes propagating…
Autonomous thermal machine for amplification and control of energetic coherence
Gonzalo Manzano, Ralph Silva, Juan M. R. Parrondo
We present a model for an autonomous quantum thermal machine comprised of two qubits capable of manipulating and even amplifying the local coherence in a non-degenerate external sy…
Boundary time crystals
F. Iemini, A. Russomanno, J. Keeling +3
In this work we introduce {\it boundary time-crystals}. Here {\it continuous} time-translation symmetry breaking occurs only in a macroscopic fraction of a many-body quantum system…
Floquet resonances close to the adiabatic limit and the effect of dissipation
Angelo Russomanno, Giuseppe E. Santoro
We study the approach to the adiabatic limit in periodically driven systems. Specifically focusing on a spin-1/2 in a magnetic field we find that, when the parameters of the Hamilt…
Optimal continuous variable quantum teleportation with limited resources
Pietro Liuzzo-Scorpo, Andrea Mari, Vittorio Giovannetti +1
Given a certain amount of entanglement available as a resource, what is the most efficient way to accomplish a quantum task? We address this question in the relevant case of contin…
Dissipation in adiabatic quantum computers: Lessons from an exactly solvable model
Maximilian Keck, Simone Montangero, Giuseppe E. Santoro +2
We introduce and study the adiabatic dynamics of free-fermion models subject to a local Lindblad bath and in the presence of a time-dependent Hamiltonian. The merit of these models…
Slow dynamics and thermodynamics of open quantum systems
Vasco Cavina, Andrea Mari, Vittorio Giovannetti
We develop a perturbation theory of quantum (and classical) master equations with slowly varying parameters, applicable to systems which are externally controlled on a time scale m…
Stabilizing strongly correlated photon fluids with non-Markovian reservoirs
José Lebreuilly, Alberto Biella, Florent Storme +4
We introduce a novel frequency-dependent incoherent pump scheme with a square-shaped spectrum as a way to study strongly correlated photons in arrays of coupled nonlinear resonator…
Density-of-states of many-body quantum systems from tensor networks
Fabian Schrodi, Pietro Silvi, Ferdinand Tschirsich +2
We present a technique to compute the microcanonical thermodynamical properties of a manybody quantum system using tensor networks. The Density Of States (DOS), and more general sp…
The capacity of coherent-state adaptive decoders with interferometry and single-mode detectors
Matteo Rosati, Andrea Mari, Vittorio Giovannetti
A class of Adaptive Decoders (AD's) for coherent-state sequences is studied, including in particular the most common technology for optical-signal processing, e.g., interferometers…
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…
Multipartite entanglement detection for hypergraph states
Maddalena Ghio, Daniele Malpetti, Matteo Rossi +2
We study the entanglement properties of quantum hypergraph states of qubits, focusing on multipartite entanglement. We compute multipartite entanglement for hypergraph states w…
Interferometric Quantum Cascade Systems
Stefano Cusumano, Andrea Mari, Vittorio Giovannetti
In this work we consider quantum cascade networks in which quantum systems are connected through unidirectional channels that can mutually interact giving rise to interference effe…
Locally optimal symplectic control of multimode Gaussian states
Uther Shackerley-Bennett, Alberto Carlini, Vittorio Giovannetti +1
The relaxation of a system to a steady state is a central point of interest in many attempts to advance control over the quantum world. In this paper, we consider control through i…
Estimating Temperature via Sequential Measurements
Antonella De Pasquale, Kazuya Yuasa, Vittorio Giovannetti
We study the efficiency of estimation procedures where the temperature of an external bath is indirectly recovered by monitoring the transformations induced on a probing system tha…
Lindbladian purification
Christian Arenz, Daniel Burgarth, Vittorio Giovannetti +2
In a recent work [D. K. Burgarth et al., Nat. Commun. 5, 5173 (2014)] it was shown that a series of frequent measurements can project the dynamics of a quantum system onto a subspa…
Optimal quantum state discrimination via nested binary measurements
Matteo Rosati, Giacomo De Palma, Andrea Mari +1
A method to compute the optimal success probability of discrimination of N arbitrary quantum states is presented, based on the decomposition of any N-outcome measurement into seque…
Multipartite entanglement after a quantum quench
Silvia Pappalardi, Angelo Russomanno, Alessandro Silva +1
We study the multipartite entanglement of a quantum many-body system undergoing a quantum quench. We quantify multipartite entanglement through the quantum Fisher information (QFI)…
