On the distribution of the mean energy in the unitary orbit of quantum states
Raffaele Salvia, Vittorio Giovannetti
Given a closed quantum system, the states that can be reached with a cyclic process are those with the same spectrum as the initial state. Here we prove that, under a very general…
Quantum Chaos and the Correspondence Principle
Jiaozi Wang, Giuliano Benenti, Giulio Casati +1
The correspondence principle is a cornerstone in the entire construction of quantum mechanics. This principle has been recently challenged by the observation of an early-time expon…
Stochastic collision model approach to transport phenomena in quantum networks
Diana A. Chisholm, Guillermo García-Pérez, Matteo A. C. Rossi +2
Noise-assisted transport phenomena highlight the nontrivial interplay between environmental effects and quantum coherence in achieving maximal efficiency. Due to the complexity of…
Maximum power heat engines and refrigerators in the fast-driving regime
Vasco Cavina, Paolo A. Erdman, Paolo Abiuso +2
We study the optimization of the performance of arbitrary periodically driven thermal machines. Within the assumption of fast modulation of the driving parameters, we derive the op…
Bounding the quantum capacity with flagged extensions
Farzad Kianvash, Marco Fanizza, Vittorio Giovannetti
In this article we consider flagged extensions of convex combination of quantum channels, and find general sufficient conditions for the degradability of the flagged extension. An…
Partially Coherent Direct Sum Channels
Stefano Chessa, Vittorio Giovannetti
We introduce Partially Coherent Direct Sum (PCDS) quantum channels, as a generalization of the already known Direct Sum quantum channels. We derive necessary and sufficient conditi…
Quantum capacity analysis of multi-level amplitude damping channels
Stefano Chessa, Vittorio Giovannetti
The set of Multi-level Amplitude Damping (MAD) quantum channels is introduced as a generalization of the standard qubit Amplitude Damping Channel to quantum systems of finite dimen…
Unveiling operator growth in SYK quench dynamics
Matteo Carrega, Joonho Kim, Dario Rosa
We study non-equilibrium dynamics induced by a sudden quench of strongly correlated Hamiltonians with all-to-all interactions. By relying on a Sachdev-Ye-Kitaev (SYK) based quench…
Microscopic biasing of discrete-time quantum trajectories
Dario Cilluffo, Igor Lesanovsky, Giuseppe Buonaiuto +5
We develop a microscopic theory for biasing the quantum trajectories of an open quantum system, which renders rare trajectories typical. To this end we consider a discrete-time qua…
Charging a quantum battery via non equilibrium heat current
Francesco Tacchino, Tiago F. F. Santos, Dario Gerace +2
When a quantum system is subject to a thermal gradient it may sustain a steady non-equilibrium heat current, by entering into a so-called non equilibrium steady state (NESS). Here…
Achieving Heisenberg scaling with maximally entangled states: an analytic upper bound for the attainable root mean square error
Federico Belliardo, Vittorio Giovannetti
In this paper we explore the possibility of performing Heisenberg limited quantum metrology of a phase, without any prior, by employing only maximally entangled states. Starting fr…
Vacancy-like dressed states in topological waveguide QED
Luca Leonforte, Angelo Carollo, Francesco Ciccarello
We identify a class of dressed atom-photon states formingat the same energy of the atom at any coupling strength. As a hallmark, their photonic component is an eigenstate of the ba…
Mechanism of decoherence-free coupling between giant atoms
Angelo Carollo, Dario Cilluffo, Francesco Ciccarello
Giant atoms are a new paradigm of quantum optics going beyond the usual local coupling. Building on this, a new type of decoherence-free (DF) many-body Hamiltonians was shown in a…
Collisional picture of quantum optics with giant emitters
Dario Cilluffo, Angelo Carollo, Salvatore Lorenzo +3
The effective description of the weak interaction between an emitter and a bosonic field as a sequence of two-body collisions provides a simple intuitive picture compared to tradit…
Squeezing-enhanced communication without a phase reference
Marco Fanizza, Matteo Rosati, Michalis Skotiniotis +2
We study the problem of transmitting classical information using quantum Gaussian states on a family of phase-noise channels with a finite decoherence time, such that the phase-ref…
Discrimination of thermal baths by single qubit probes
Ilaria Gianani, Donato Farina, Marco Barbieri +3
Non-equilibrium states of quantum systems in contact with thermal baths help telling environments with different temperatures or different statistics apart. We extend these studies…
Continuous-time quantum walks in the presence of a quadratic perturbation
Alessandro Candeloro, Luca Razzoli, Simone Cavazzoni +2
We address the properties of continuous-time quantum walks with Hamiltonians of the form , being the Laplacian matrix of the underlying graph and being t…
Measuring non-Markovianity via incoherent mixing with Markovian dynamics
Dario De Santis, Vittorio Giovannetti
We introduce a measure of non-Markovianity based on the minimal amount of extra Markovian noise we have to add to the process via incoherent mixing, in order to make the resulting…
Reinforcement learning approach to non-equilibrium quantum thermodynamics
Sofia Sgroi, G. Massimo Palma, Mauro Paternostro
We use a reinforcement learning approach to reduce entropy production in a closed quantum system brought out of equilibrium. Our strategy makes use of an external control Hamiltoni…
Violation of TUR in a periodically driven work-to-work converter from weak to strong dissipation
Loris Maria Cangemi, Vittorio Cataudella, Giuliano Benenti +2
We study a model of isothermal steady-state work-to-work converter, where a single quantum two-level system (TLS) driven by time-dependent periodic external fields acts as the work…
Going beyond Local and Global approaches for localized thermal dissipation
Donato Farina, Giulio De Filippis, Vittorio Cataudella +2
Identifying which master equation is preferable for the description of a multipartite open quantum system is not trivial and has led in the recent years to the local vs. global deb…
A general framework for conformal transformations in electron optics
Gianluca Ruffato, Enzo Rotunno, Vincenzo Grillo
The implementation of log-pol transformation has recently introduced a new boost in electron optics with charged matter vortices, allowing to map conformally between linear and orb…
Bosonic quantum communication across arbitrarily high loss channels
Ludovico Lami, Martin B. Plenio, Vittorio Giovannetti +1
A general attenuator is a bosonic quantum channel that acts by combining the input with a fixed environment state in a beam splitter of transmissivity . If is…
Quantum correlations in -symmetric systems
Federico Roccati, Salvatore Lorenzo, G. Massimo Palma +3
We study the dynamics of correlations in a paradigmatic setup to observe -symmetric physics: a pair of coupled oscillators, one subject to a gain one to a loss. Start…
