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 …

Distributed quantum metrology can enhance the sensitivity for sensing spatially distributed
parameters beyond the classical limits. Here we demonstrate distributed quantum phase …

The interest in a system often resides in the interplay among different parameters governing
its evolution. It is thus often required to access many of them at once for a complete …

Distributed quantum metrology has drawn intense interest as it outperforms the optimal
classical counterparts in estimating multiple distributed parameters. However, most schemes …

We show that quantum entanglement can provide an exponential advantage in learning
properties of a bosonic continuous-variable (CV) system. The task we consider is estimating …

Relevant metrological scenarios involve the simultaneous estimation of multiple parameters.
The fundamental ingredient to achieve quantum-enhanced performance is based on the use …

Distributed quantum sensing can provide quantum-enhanced sensitivity beyond the shot-
noise limit (SNL) for sensing spatially distributed parameters. To date, distributed quantum …

Squeezing currently represents the leading strategy for quantum enhanced precision
measurements of a single parameter in a variety of continuous-and discrete-variable …
