‘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.

Researchers suggest novel way to generate a light source made from entangled photons

Credit: Pixabay/CC0 Public Domain Entanglement is a strange phenomenon in quantum physics where two particles are inherently connected to each other no matter the distance between them. When one is measured, the other measurement is instantly a given. Researchers from Purdue University have proposed a novel, unconventional approach to generate a special light source made … Read more
