Quantum sensing has become a broad field. It is generally related with the idea of using
quantum resources to boost the performance of a number of practical tasks, including the …

Computational methods have been established as cornerstones in optical imaging and
holography in recent years. Every year, the dependence of optical imaging and holography …

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 …

Rayleigh's criterion for resolving two incoherent point sources has been the most influential
measure of optical imaging resolution for over a century. In the context of statistical image …

The purpose of quantum technologies is to explore how quantum effects can improve on
existing solutions for the treatment of information. Quantum photonics sensing holds great …

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 …

The Rayleigh criterion specifies the minimum separation between two incoherent point
sources that may be resolved into distinct objects. We revisit this problem by examining the …

We establish the multiparameter quantum Cramér-Rao bound for simultaneously estimating
the centroid, the separation, and the relative intensities of two incoherent optical point …

We determine the ultimate potential of quantum imaging for boosting the resolution of a far-
field, diffraction-limited, linear imaging device within the paraxial approximation. First, we …

The Laguerre-Gaussian (LG) modes constitute a complete basis set for representing the
transverse structure of a paraxial photon field in free space. Earlier workers have shown how …
