The extraordinary sensitivity of plasmonic sensors is well-known in the optics and photonics
community. These sensors exploit simultaneously the enhancement and the localization of …

Quantum metrology is one of the most promising applications of quantum technologies. The
aim of this research field is the estimation of unknown parameters exploiting quantum …

Time correlated photon pairs are used to produce heralded single photon states for quantum
integrated circuits. These states are generated by photon sources, which are called …

We show that both the classical as well as the quantum definitions of the Fisher information
faithfully identify resourceful quantum states in general quantum resource theories, in the …

The striking differences between quantum and classical systems predicate disruptive
quantum technologies. We peruse quantumness from a variety of viewpoints, concentrating …

Quantum radars and lidars are a novel, much-discussed, and rapidly evolving field of
quantum science and technology, promising remarkable advantages in such basic tasks as …

We demonstrate that the negative volume of any s-parametrized quasiprobability, including
the Glauber-Sudashan P function, can be consistently defined and forms a continuous …

We study asymptotic state transformations in continuous variable quantum resource
theories. In particular, we prove that monotones displaying lower semicontinuity and strong …

In this focused review we survey recent progress in the development of resource theories of
nonclassical light. We introduce the resource theoretical approach, in particular how it …

Two basic ingredients in the quantum formalism are the concepts of states and observables,
and apart from the average value (which includes the Born probability as a paramountly …
