| description | Compact devices provide new ways to generate and detect optical vortex beams
A large-scale vortex is an extraordinary phenomenon to behold, be it a hurricane in the North Atlantic Ocean or the Great Red Spot on Jupiter. A vortex on a small scale is equally fascinating, especially when its quantum nature starts to emerge. Alexei Abrikosov won a Nobel Prize by introducing vortices in a phenomenological model to describe a new type of superconductor in 1950s (
1
), which turned out to be a feature of paired electrons in supercurrent. A very different type of vortex can be created for light (
2
). On pages 760 and 763 of this issue, Zhang
