Introduction
Bohnishikha Ghosh graduated with a BS-MS degree from the Department of Physical Sciences, at Indian Institute of Science Education and Research Kolkata. Her MS thesis was carried out at the Institute of Mathematical Sciences, Chennai, wherein she focused on the theoretical aspects of non-classicality of light. She is currently a PhD student at the Faculty of Physics, University of Warsaw and works on the observation of optical analogue of quantum backflow.

The local propagation and the energy flux in structured optical fields are often associated with the Poynting vector. However, the local phase gradient (i.e., local wavevector) in monochromatic fields in free space is described by another fundamental quantity: the canonical momentum density. Distributions of the Poynting and canonical momentum dens...
M. V. Berry’s work [J. Phys. A 43, 415302 (2010)1751-811310.1088/1751-8113/43/41/415302] highlighted the correspondence between backflow in quantum mechanics and superoscillations in waves. Superoscillations refer to situations where the local oscillation of a superposition is faster than its fastest Fourier component. This concept has been used to...

The well-known interference pattern of bright and dark fringes was first observed for light beams
back in 1801 by Thomas Young. The maximum visibility fringes occur when the irradiance of the
two beams is equal, and as the ratio of the beam intensities deviates from unity, fringe visibility
decreases. An interesting outcome that might not be entire...

Super-resolution microscopy techniques have pushed the limits of resolution in optical imaging by more than an order of magnitude. However, these methods often require long acquisition times as well as complex setups and sample preparation protocols. Super-resolution Optical Fluctuation Imaging (SOFI) emerged over ten years ago as an approach that...

Maximal advantage in two-way communication via maximal violation of an inequality associated with the `Guess Your Neighbour's Input' game has been theoretically and experimentally established quite recently [Del Santo et al., PRL 18, Massa et al., OSA 18] using a single-photon two-mode entangled state. We argue that such a maximal advantage can be...
