Scientists Just Used Sunlight To Pull Off a Quantum Physics Feat Once Thought Impossible

[00:00:00]Scientists just pulled off quantum ghost imaging using nothing but sunlight. This was supposed to be impossible without stable lasers, but researchers at Xiamen University used a sun tracker and a plastic fiber to pump raw sunlight into a crystal. The crystal spit out correlated photon pairs, even though sunlight fluctuates constantly. They used those photons to reconstruct a ghost face with over 90% visibility. No lasers, no electrical power, just the sun doing quantum physics. [music]
