‘Twisty’ photons could turbocharge next-gen quantum communication

A quantum emitter capable of emitting single photons integrated with a geared-shaped resonator. By fine-tuning the arrangement of the emitter and the gear-shaped resonator, it’s possible to leverage the interaction between the photon’s spin and its orbital angular momentum to create individual “twisty” photons on demand.
