Entangled Photons in a CubeSat
Putting compact quantum science into space could support a next-gen internet.
As quantum communication moves forward, a few researchers are eyeing something much bigger: a quantum internet—a global network of quantum devices tied together by quantum-encrypted links. One route to that, some believe, could lie in space, using small, quantum-enabled nanosatellites, or CubeSats, as network nodes. OPN talked with Alexander Ling of the National University of Singapore about his team’s efforts to pack quantum technology into CubeSats—most recently reported in Optica (doi: 10.1364/OPTICA.387306)—and what this might someday enable.
