On August 7, 2026, ScienceDaily reported an outdoor experiment that generated entangled photons directly from sunlight, with about 94% similarity between the twin particles. The work hints at a lower-energy path to quantum links that today rely on carefully tuned lasers and optics (ScienceDaily). Sunlight quantum entanglement moves from theory to field test Most entanglement […]
