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 …

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 …

Compared to DSLR cameras, smartphone cameras have smaller sensors, which limits their
spatial resolution; smaller apertures, which limits their light gathering ability; and smaller …

The wave-particle duality of light introduces two fundamental problems to imaging, namely,
the diffraction limit and the photon shot noise. Quantum information theory can tackle them …

We present the experimental implementation of simultaneous spatial multimode
demultiplexing as a distance measurement tool. We use this technique to estimate the …

I propose a spatial-mode demultiplexing (SPADE) measurement scheme for the far-field
imaging of spatially incoherent optical sources. For any object too small to be resolved by …

The application of quantum estimation theory to the problem of imaging two incoherent point
sources has recently led to new insights and better measurements for incoherent imaging …

Detecting the faint emission of a secondary source in the proximity of the much brighter one
has been the most severe obstacle for using direct imaging in searching for exoplanets …

Passive imaging receivers that demultiplex an incoherent optical field into a set of
orthogonal spatial modes prior to detection can surpass canonical diffraction limits on spatial …

Lossy bosonic channels play an important role in a number of quantum information tasks,
since they well approximate thermal dissipation in an experiment. Here, we characterize …
