Joint estimation of position and momentum with arbitrarily high precision using non-Gaussian states
Massimo Frigerio, Matteo G. A. Paris, Carlos Ernesto Lopetegui +1
We address the joint estimation of changes in the position and linear momentum of a quantum particle or, equivalently, changes in the complex field of a bosonic mode. Although thes…
Overcoming sloppiness for enhanced metrology in continuous-variable quantum statistical models
Massimo Frigerio, Matteo G. A. Paris
Multi-parameter statistical models may depend only on some functions of the parameters that are fewer than the number of initial parameters themselves. Such \emph{sloppy} statistic…
Resourcefulness of non-classical continuous-variable quantum gates
Massimo Frigerio, Antoine Debray, Nicolas Treps +1
In continuous-variable quantum computation, identifying key elements that enable a quantum computational advantage is a long-standing issue. Starting from the standard results on t…
Enhanced quantum transport in chiral quantum walks
Emilio Annoni, Massimo Frigerio, Matteo G. A. Paris
Quantum transport across discrete structures is a relevant topic of solid state physics and quantum information science, which can be suitably studied in the context of continuous-…
Quantum routing of information using chiral quantum walks
Alberto Bottarelli, Massimo Frigerio, Matteo G. A. Paris
We address routing of classical and quantum information over quantum network, and show how to exploit chirality to achieve nearly optimal and robust transport. In particular, we pr…
Swift chiral quantum walks
Massimo Frigerio, Matteo G. A. Paris
A continuous-time quantum walk (CTQW) is sedentary if the return probability in the starting vertex is close to one at all times. Recent results imply that, when starting from a ma…
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-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…
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…
Nonclassical steering and the Gaussian steering triangoloids
Massimo Frigerio, Stefano Olivares, Matteo G. A. Paris
Nonclassicality according to the singularity or negativity of the Glauber P-function is a powerful resource in quantum information, with relevant implications in quantum optics. In…
Nonclassical steering with two-mode Gaussian states
Massimo Frigerio, Claudio Destri, Stefano Olivares +1
Singularity or negativity of Glauber P-function is a widespread notion of nonclassicality, with important implications in quantum optics and with the character of an irreducible re…
