Thirty years ago, Coullet et al. proposed that a special optical field exists in laser cavities
bearing some analogy with the superfluid vortex. Since then, optical vortices have been …

Structured light with inhomogeneous phase, amplitude, and polarization spatial distributions
that represent an infinite-dimensional space of eigenstates for light as the ideal carrier can …

In recent years, there has been a rising interest in high‐dimensional quantum states and
their impact on quantum communication. Indeed, the availability of an enlarged Hilbert …

Photonic quantum technologies represent a promising platform for several applications,
ranging from long-distance communications to the simulation of complex phenomena …

Optical vortices (OVs) carrying orbital angular momentum (OAM) have attracted
considerable interest in the field of optics and photonics owing to their peculiar optical …

Structured light refers to the generation and application of custom light fields. As the tools

Twenty-five years ago Allen, Beijersbergen, Spreeuw, and Woerdman published their
seminal paper establishing that light beams with helical phase-fronts carried an orbital …

Vector beams, and in particular vector vortex beams, have found many applications in recent
times, both as classical fields and as quantum states. While much attention has focused on …

Quantum teleportation provides a 'disembodied'way to transfer quantum states from one
object to another at a distant location, assisted by previously shared entangled states and a …

Despite a plethora of applications ranging from quantum memories to high-resolution
lithography, the current technologies to generate vector vortex beams (VVBs) suffer from …
