Extracting work from correlated many-body quantum systems
Raffaele Salvia, Vittorio Giovannetti
The presence of correlations in the input state of a non-interacting many-body quantum system can lead to an increase in the amount of work we can extract from it under global unit…
Non-asymptotic Heisenberg scaling: experimental metrology for a wide resources range
Valeria Cimini, Emanuele Polino, Federico Belliardo +5
Adopting quantum resources for parameter estimation discloses the possibility to realize quantum sensors operating at a sensitivity beyond the standard quantum limit. Such approach…
An agnostic-Dolinar receiver for coherent states classification
Fabio Zoratti, Nicola Dalla Pozza, Marco Fanizza +1
We consider the problem of discriminating quantum states, where the task is to distinguish two different quantum states with a complete classical knowledge about them, and the prob…
Quantum collision models: open system dynamics from repeated interactions
Francesco Ciccarello, Salvatore Lorenzo, Vittorio Giovannetti +1
We present an extensive introduction to quantum collision models (CMs), also known as repeated interactions schemes: a class of microscopic system-bath models for investigating ope…
Hilbert curve vs Hilbert space: exploiting fractal 2D covering to increase tensor network efficiency
Giovanni Cataldi, Ashkan Abedi, Giuseppe Magnifico +4
We present a novel mapping for studying 2D many-body quantum systems by solving an effective, one-dimensional long-range model in place of the original two-dimensional short-range…
Quantum Energy Lines and the optimal output ergotropy problem
Salvatore Tirone, Raffaele Salvia, Vittorio Giovannetti
We study the transferring of useful energy (work) along a transmission line that allows for partial preservation of quantum coherence. As a figure of merit we adopt the maximum val…
Testing identity of collections of quantum states: sample complexity analysis
Marco Fanizza, Raffaele Salvia, Vittorio Giovannetti
We study the problem of testing identity of a collection of unknown quantum states given sample access to this collection, each state appearing with some known probability. We show…
Estimating Quantum and Private capacities of Gaussian channels via degradable extensions
Marco Fanizza, Farzad Kianvash, Vittorio Giovannetti
We present upper bounds on the quantum and private capacity of single-mode, phase-insentitive Bosonic Gaussian Channels based on degradable extensions. Our findings are state-of-th…
Incompatibility in Quantum Parameter Estimation
Federico Belliardo, Vittorio Giovannetti
In this paper we introduce a measure of genuine quantum incompatibility in the estimation task of multiple parameters, that has a geometric character and is backed by a clear opera…
