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 …

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

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 …

Spatiotemporal sculpturing of light pulse with ultimately sophisticated structures represents a
major goal of the everlasting pursue of ultra-fast information transmission and processing as …

Structured waves are ubiquitous for all areas of wave physics, both classical and quantum,
where the wavefields are inhomogeneous and cannot be approximated by a single plane …

Entanglement is a quintessential quantum mechanical phenomenon with no classical
equivalent. First discussed by Einstein, Podolsky, and Rosen and formally introduced by …

Four-mode multiplexing and manipulation technologies are reviewed in the context of space-
division multiplexing (SDM) optical communication systems. These are multiplane light …

Two processes of photon-pair creation can be arranged such that the paths of the emitted
photons are identical. The path information is thereby not erased but rather never born in the …

Structured light refers to the ability to tailor optical patterns in all its degrees of freedom, from
conventional 2D transverse patterns to exotic forms of 3D, 4D, and even higher-dimensional …

We study multiparameter sensing of two-dimensional (2D) and three-dimensional (3D)
vector fields within the Bayesian framework for SU (2) quantum interferometry. We establish …
