Cost-effective temperature estimation strategies for thermal states with probabilistic quantum metrology
Massimo Frigerio, Stefano Olivares, Matteo G. A. Paris
In probabilistic quantum metrology, one aims at finding weak measurements that concentrate the Fisher Information on the resulting quantum states, post-selected according to the we…
Quantum probes for the characterization of nonlinear media
Alessandro Candeloro, Sholeh Razavian, Matteo Piccolini +3
Active optical media leading to interaction Hamiltonians of the form represent a crucial resource for quantum optical technology. In this paper…
Multi-parameter quantum metrology with discrete-time quantum walks
Mostafa Annabestani, Majid Hassani, Dario Tamascelli +1
We address multi-parameter quantum estimation for one-dimensional discrete-time quantum walks and its applications to quantum metrology. We use the quantum walker as a probe for un…
An Enhanced Photonic Quantum Finite Automaton
Alessandro Candeloro, Carlo Mereghetti, Beatrice Palano +3
In a recent paper we have described an optical implementation of a measure-once one-way quantum finite automaton recognizing a well-known family of unary periodic languages, accept…
Multiclass classification of dephasing channels
Adriano M. Palmieri, Federico Bianchi, Matteo G. A. Paris +1
We address the use of neural networks (NNs) in classifying the environmental parameters of single-qubit dephasing channels. In particular, we investigate the performance of linear…
Novel technique for the active stabilization of the relative phase between seed and pump in an optical parametric oscillator
Simone Cialdi, Edoardo Suerra, Matteo G. A. Paris +1
We design and demonstrate a novel technique for the active stabilization of the relative phase between seed and pump in an optical parametric oscillator (OPO). We show that two err…
On the properties of the asymptotic incompatibility measure in multiparameter quantum estimation
Alessandro Candeloro, Matteo G. A. Paris, Marco G. Genoni
We address the use of asymptotic incompatibility (AI) to assess the quantumness of a multiparameter quantum statistical model. AI is a recently introduced measure which quantifies…
Quantum-classical distance as a tool to design optimal chiral quantum walk
Massimo Frigerio, Claudia Benedetti, Stefano Olivares +1
Continuous-time quantum walks (CTQWs) provide a valuable model for quantum transport, universal quantum computation and quantum spatial search, among others. Recently, the empoweri…
Phase noise mitigation by a realistic optical parametric oscillator
Michele N. Notarnicola, Marco G. Genoni, Simone Cialdi +2
We address the exploitation of an optical parametric oscillator (OPO) in the task of mitigating, at least partially, phase noise produced by phase diffusion. In particular, we anal…
Quantum Compiling by Deep Reinforcement Learning
Lorenzo Moro, Matteo G. A. Paris, Marcello Restelli +1
The architecture of circuital quantum computers requires computing layers devoted to compiling high-level quantum algorithms into lower-level circuits of quantum gates. The general…
Universal set of quantum gates for the flip-flop qubit in the presence of 1/f noise
Elena Ferraro, Davide Rei, Matteo Paris +1
Impurities hosted in semiconducting solid matrices represent an extensively studied platform for quantum computing applications. In this scenario, the so-called flip-flop qubit eme…
Exploiting Gaussian steering to probe non-Markovianity due to the interaction with a structured environment
Massimo Frigerio, Samaneh Hesabi, Davood Afshar +1
We put forward a measure based on Gaussian steering to quantify the non-Markovianity of continuous-variable (CV) Gaussian quantum channels. We employ the proposed measure to assess…
Generalized quantum-classical correspondence for random walks on graphs
Massimo Frigerio, Claudia Benedetti, Stefano Olivares +1
We introduce a minimal set of physically motivated postulates that the Hamiltonian H of a continuous-time quantum walk should satisfy in order to properly represent the quantum cou…
Role of topology in determining the precision of a finite thermometer
Alessandro Candeloro, Luca Razzoli, Paolo Bordone +1
Temperature fluctuations of a finite system follows the Landau bound where is the heat capacity of the system. In turn, the same bound sets a limit to the…
