Unlike electronics, optics do not follow Moore's law. This statement, expressed by Microsoft's
Bernard Kress, refers to the hard challenges to solve in augmented reality hardware. While …

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 …

Replacing curved and bulky optical elements with thin and lightweight counterparts is a
persistent pursuit of the optical society. Metasurfaces, as two-dimensional artificial …

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 …

It is well known in Bayesian estimation theory that the conditional estimator attains the
minimum mean squared error (MMSE) for estimating a scalar parameter of interest. In …

Spatial-mode demultiplexing (SPADE) has recently been adopted to measure the
separation in the transverse plane between two incoherent point-like sources with sub …

In this paper we investigate the quantum information theoretical limits to several tasks
related to lifetime estimation and discrimination of a two-level spontaneous optical emitter …

Resolving the separation between two incoherent optical sources with high precision is of
great significance for fluorescence imaging and astronomical observations. In this paper, we …

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

Interferometric image processing systems based on image inversion normally use multiple
paths with inversion mirrors. Since such systems must meet strict requirements of alignment …
