Quantum versus classical many-body batteries
Gian Marcello Andolina, Maximilian Keck, Andrea Mari +2
Quantum batteries are quantum mechanical systems with many degrees of freedom which can be used to store energy and that display fast charging. The physics behind fast charging is…
Maximum power and corresponding efficiency for two-level heat engines and refrigerators: optimality of fast cycles
Paolo Andrea Erdman, Vasco Cavina, Rosario Fazio +2
We study how to achieve the ultimate power in the simplest, yet non trivial, model of a thermal machine, namely a two-level quantum system coupled to two thermal baths. Without mak…
Optimal Quantum Subtracting Machine
Farzad Kianvash, Marco Fanizza, Vittorio Giovannetti
The impossibility of undoing a mixing process is analysed in the context of quantum information theory. The optimal machine to undo the mixing process is studied in the case of pur…
Two-parameter Hong-Ou-Mandel dip
Yu Yang, Luping Xu, Vittorio Giovannetti
A modification of the standard Hong-Ou-Mandel interferometer is proposed which allows one to replicate the celebrated coincidence dip in the case of two-independent delay parameter…
Exciting a Bound State in the Continuum through Multi-Photon Scattering plus Delayed Quantum Feedback
Giuseppe Calajò, Yao-Lung L. Fang, Harold U. Baranger +1
Excitation of a bound state in the continuum (BIC) through scattering is problematic since it is by definition uncoupled. Here, we consider a type of dressed BIC and show that it c…
Structured Quantum Projectiles
Hugo Larocque, Robert Fickler, Eliahu Cohen +4
Matter wave interferometry is becoming an increasingly important technique in quantum metrology. However, unlike its photonic counterpart, this technique relies on the interference…
Generation of electron vortices using non-exact electric fields
Amir H. Tavabi, Hugo Larocque, Peng-Han Lu +5
Vortices in electron beams can manifest several types of topological phenomena, such as the formation of exotic structures or interactions with topologically structured electromagn…
Persistent currents by reservoir engineering
Maximilian Keck, Davide Rossini, Rosario Fazio
We demonstrate that persistent currents can be induced in a quantum system in contact with a structured reservoir, without the need of any applied gauge field. The working principl…
All-optical implementation of collision-based evolutions of open quantum systems
Álvaro Cuevas, Andrea Geraldi, Carlo Liorni +5
We present a new optical scheme enabling the implementation of highly stable and configurable non-Markovian dynamics. Here one photon qubit can circulate in a multipass bulk geomet…
A dynamical approach to ancilla assisted quantum thermometry
Alexander Holm Kiilerich, Antonella De Pasquale, Vittorio Giovannetti
A scheme for improving the sensitivity of quantum thermometry is proposed where the sensing quantum system used to recover the temperature of an external bath is dynamically couple…
Quantum Thermometry
Antonella De Pasquale, Thomas M. Stace
We discuss the application of techniques of quantum estimation theory and quantum metrology to thermometry. The ultimate limit to the precision at which the temperature of a system…
Extractable work, the role of correlations, and asymptotic freedom in quantum batteries
Gian Marcello Andolina, Maximilian Keck, Andrea Mari +3
We investigate a quantum battery made of N two-level systems, which is charged by an optical mode via an energy-conserving interaction. We quantify the fraction E(N) of energy stor…
Variational approach to the optimal control of coherently driven, open quantum system dynamics
Vasco Cavina, Andrea Mari, Alberto Carlini +1
Quantum coherence inherently affects the dynamics and the performances of a quantum machine. Coherent control can, at least in principle, enhance the work extraction and boost the…
Entropy production and asymptotic factorization via thermalization: a collisional model approach
Stefano Cusumano, Vasco Cavina, Maximilian Keck +2
The Markovian evolution of an open quantum system is characterized by a positive entropy production, while the global entropy gets redistributed between the system and the environm…
Hidden Order in Quantum Many-body Dynamics of Driven-Dissipative Nonlinear Photonic Lattices
Jirawat Tangpanitanon, Stephen R. Clark, V. M. Bastidas +3
We study the dynamics of nonlinear photonic lattices driven by two-photon parametric processes. By means of matrix-product-state based calculations, we show that a quantum many-bod…
Bridging thermodynamics and metrology in non-equilibrium Quantum Thermometry
Vasco Cavina, Luca Mancino, Antonella De Pasquale +7
Single-qubit thermometry presents the simplest tool to measure the temperature of thermal baths with reduced invasivity. At thermal equilibrium, the temperature uncertainty is link…
Degradation of Entanglement in Markovian Noise
Dario Gatto, Antonella De Pasquale, Vittorio Giovannetti
The entanglement survival time is defined as the maximum time a system which is evolving under the action of local Markovian, homogenous in time noise, is capable to preserve the e…
Ultrafast Generation and Control of an Electron Vortex Beam via Chiral Plasmonic Near Fields
G. M. Vanacore, G. Berruto, I. Madan +12
Vortex-carrying matter waves, such as chiral electron beams, are of significant interest in both applied and fundamental science. Continuous wave electron vortex beams are commonly…
Scrambling and entanglement spreading in long-range spin chains
Silvia Pappalardi, Angelo Russomanno, Bojan Žunkovič +3
We study scrambling in connection to multipartite entanglement dynamics in regular and chaotic long-range spin chains, characterized by a well defined semi-classical limit. For reg…
System-environment correlations and Markovian embedding of quantum non-Markovian dynamics
Steve Campbell, Francesco Ciccarello, G. Massimo Palma +1
We study the dynamics of a quantum system whose interaction with an environment is described by a collision model, i.e. the open dynamics is modelled through sequences of unitary i…
Optimal universal learning machines for quantum state discrimination
Marco Fanizza, Andrea Mari, Vittorio Giovannetti
We consider the problem of correctly classifying a given quantum two-level system (qubit) which is known to be in one of two equally probable quantum states. We assume that this ta…
