A general estimation framework for continuous-variable systems
Luca Innocenti, Simone Artini, Diana A. Chisholm +5
We show that informational completeness, while sufficient to have a bijection between ideal measurement probabilities and quantum states, does not guarantee statistically stable re…
Non-equilibrium thermodynamics of collapse models in the strongly non-Gaussian regime
Pedro B. Melo, Pedro V. Paraguassú, Simone Artini +3
Standard objective collapse models offer a unified approach to the quantum measurement problem but predict an unphysical, indefinite increase in the energy of the system. The dissi…
Non-equilibrium quantum thermodynamics of a memory-bearing open-system process
Biagio G. Banigi, Eric Lutz, Mauro Paternostro
We show the emergence of memory effects in the dynamics of a driven two-level system interacting with a composite environment, and analyze their influence on work, heat and entropy…
The non-stabilizerness cost of quantum state estimation
Gabriele Lo Monaco, Salvatore Lorenzo, Alessandro Ferraro +3
We study the non-stabilizer resources required to achieve informational completeness in single-setting quantum state estimation scenarios. We consider fixed-basis projective measur…
Coherent heat exchange in a prethermalizing open quantum system
Simone Artini, Mauro Paternostro, Salvatore Lorenzo
We investigate a simple model exhibiting a prethermal phase, i.e. a metastable state that emerges before full thermalization, through the framework of quantum stochastic thermodyna…
A machine learning based approach to the identification of spectral densities in quantum open systems
Jessica Barr, Shreyasi Mukherjee, Alessandro Ferraro +2
We present a machine learning-based approach for characterising the environment that affects the dynamics of an open quantum system. We focus on the case of an exactly solvable spi…
Broken Detailed Balance and Entropy Production in CPTP Quantum Brownian Motion
Simone Artini, Gabriele Lo Monaco, Alberto Imparato +2
We rigorously analyze the non-equilibrium thermodynamic behavior of various formulations of quantum Brownian motion (QBM) using the framework of stochastic thermodynamics. While th…
Roadmap on Quantum Thermodynamics
Steve Campbell, Irene D'Amico, Mario A. Ciampini +66
The last two decades has seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicabilit…
Quantum reservoir computing for photonic entanglement witnessing
Danilo Zia, Luca Innocenti, Giorgio Minati +10
Accurately estimating properties of quantum states, such as entanglement, while essential for the development of quantum technologies, remains a challenging task. Standard approach…
Machine Learning-Enhanced Characterisation of Structured Spectral Densities: Leveraging the Reaction Coordinate Mapping
Jessica Barr, Alessandro Ferraro, Mauro Paternostro +1
Spectral densities encode essential information about system-environment interactions in open-quantum systems, playing a pivotal role in shaping the system's dynamics. In this work…
Entanglement distribution through separable states via a zero-added-loss photon multiplexing inspired protocol
Conall J. Campbell, Adam G. Hawkins, Giorgio Zicari +2
The recently proposed zero-added-loss multiplexing (ZALM) source of entangled photons enables higher efficiency in entanglement distribution than spontaneous parametric down-conver…
The role of initial coherence in the phase-space entropy production rate
Giorgio Zicari, Barış Çakmak, Mauro Paternostro
The second law of thermodynamics can be expressed in terms of entropy production, which can be used to quantify the degree of irreversibility of a process. In this Chapter, we cons…
Characterizing the spontaneous collapse of a wavefunction through entropy production
Simone Artini, Mauro Paternostro
We investigate the phenomenology leading to the non-conservation of energy of the continuous spontaneous localization (CSL) model from the viewpoint of non-equilibrium thermodynami…
Non-equilibrium readiness and accuracy of Gaussian Quantum Thermometers
Luca Mancino, Marco G. Genoni, Marco Barbieri +1
The dimensionality of a thermometer is key in the design of quantum thermometry schemes. In general, the phenomenology that is typical of finite-dimensional quantum thermometry doe…
Characterizing irreversibility in open quantum systems
T. B. Batalhao, S. Gherardini, J. P. Santos +2
Irreversibility is a fundamental concept with important implications at many levels. It pinpoints the fundamental difference between the intrinsically reversible microscopic equati…
Non-equilibrium thermodynamics of continuously measured quantum systems: a circuit-QED implementation
P. G. Di Stefano, J. J. Alonso, E. Lutz +2
We propose a fully operational framework to study the non-equilibrium thermodynamics of a quantum system that is coupled to a detector whose state is continuously monitored…
Einstein-Podolsky-Rosen Steering and Quantum Steering Ellipsoids: Optimal Two-Qubit States and Projective Measurements
R. McCloskey, A. Ferraro, M. Paternostro
We identify the families of states that maximise some recently proposed quantifiers of Einstein-Podolsky-Rosen (EPR) steering and the volume of the Quantum Steering Ellipsoid (QSE)…
Assessing the non-equilibrium thermodynamics in a quenched quantum many-body system via single projective measurements
L. Fusco, S. Pigeon, T. J. G. Apollaro +6
We analyse the nature of the statistics of the work done on or by a quantum many-body system brought out of equilibrium. We show that, for the sudden quench and for an initial stat…
Out of equilibrium thermodynamics of quantum harmonic chains
A. Carlisle, L. Mazzola, M. Campisi +7
The thermodynamic implications for the out-of-equilibrium dynamics of quantum systems are to date largely unexplored, especially for quantum many-body systems. In this paper we inv…
Vortex entanglement in Bose-Einstein condensates coupled to Laguerre-Gauss beams
N. Lo Gullo, S. McEndoo, Th. Busch +1
We study the establishment of vortex entanglement in remote and weakly interacting Bose Einstein condensates. We consider a two-mode photonic resource entangled in its orbital angu…
