Non-classical correlations in optical beams offer an unprecedented opportunity for
surpassing the conventional limits of sensitivity and resolution in optical measurements and …

In this review we present the potentialities and the achievements of the use of non-classical
photon-number correlations in twin-beam states for many applications, ranging from imaging …

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 …

We present an extended collision model to simulate the dynamics of an open quantum
system. In our model, the unit to represent the environment is, instead of a single particle, a …

We consider a two-level open quantum system undergoing pure dephasing, dissipative, or
multiply decohering dynamics and show that whenever the dynamics is non-Markovian, the …

Memory effects in the dynamics of open systems have been the subject of significant interest
in the last decades. The methods involved in quantifying this effect, however, are often …

We consider a model of non-Markovian quantum Brownian motion that consists of a
harmonic oscillator bilinearly coupled to a thermal bath, both via its position and via its …

Quantum non-Markovianity is crucially related to the study of dynamical maps, which are
usually derived for initially factorized system-bath states. We demonstrate that linear …

By employing the full counting statistics formalism, we characterize the first moment of
energy that is exchanged during a generally non-Markovian evolution in nondriven …

The nonincreasing feature of temporal quantum steering under a completely positive trace-
preserving (CPTP) map, as proposed by Chen et al.[Phys. Rev. Lett. 116, 020503 (2016) …
