Existing super-resolution methods of optical imaging hold a solid place as an application in
natural sciences, but many new developments allow for beating the diffraction limit in a more …

Quantum-inspired superresolution methods surpass the Rayleigh limit in imaging, or the
analogous Fourier limit in spectroscopy. This is achieved by carefully extracting the …

We study super-resolution imaging theoretically using a distant n-mode interferometer in the
microwave regime for passive remote sensing, used, eg, for satellites like the “Soil Moisture …

Imaging using interferometer arrays based on the Van Cittert–Zernike theorem has been
widely used in astronomical observation. Recently it was shown that superresolution can be …

As a method to extract information from optical systems, imaging can be viewed as a
parameter estimation problem. The fundamental precision in locating one emitter or …

The resolution limits of classical spectroscopy can be surpassed by quantum-inspired
methods leveraging the information contained in the phase of the complex electromagnetic …

The basic idea behind Rayleigh's criterion on resolving two incoherent optical point sources
is that the overlap between the spatial modes from different sources would reduce the …

The optimal quantum measurements for estimating individual parameters might be
incompatible with each other, so they cannot be jointly performed. The tradeoff between the …

We investigate the resolution for imaging two pointlike entangled sources by using the
method of moments and spatial-mode demultiplexing, where the pointlike entangled …

We investigate theoretically coherent detection implemented simultaneously on a set of
mutually orthogonal spatial modes in the image plane as a method to characterize …
