Sunlight creates quantum entanglement once thought to require lasers

Scientists have successfully generated quantum entanglement directly from sunlight, which could provide a lower-energy alternative to lasers in quantum technology. The experiment, conducted outdoors, produced entangled photons with a 94% similarity to an ideal state. This breakthrough may lead to the development of simpler quantum satellites and more energy-efficient quantum computing. It also has the potential to enhance secure communications systems.
