All light has structure, but only recently has it been possible to control it in all its degrees of
freedom and dimensions, fuelling fundamental advances and applications alike. Here we …

Structured light, especially beams carrying orbital angular momentum (OAM), has gained
much interest due to its unique amplitude and phase structures. In terms of communication …

Structured light refers to the arbitrarily tailoring of optical fields in all their degrees of freedom
(DoFs), from spatial to temporal. Although orbital angular momentum (OAM) is perhaps the …

Structured light refers to the generation and application of custom light fields. As the tools
and technology to create and detect structured light have evolved, steadily the applications …

BACKGROUND Optical vortices provide one of the promising solutions for enhancing the
capacity of data multiplexing to meet an unprecedented growth in big data and internet traffic …

Orbital angular momentum (OAM), which describes tailoring the spatial physical dimension
of light waves into a helical phase structure, has given rise to many applications in optical …

Since its discovery, quantum entanglement has challenged some of the best established
views of the world: locality and reality. Quantum technologies promise to revolutionize …

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

Twisted photons can be used as alphabets to encode information beyond one bit per single
photon. This ability offers great potential for quantum information tasks, as well as for the …

Concerted efforts are underway to establish an infrastructure for a global quantum Internet to
realise a spectrum of quantum technologies. This will enable more precise sensors, secure …
