Scientists just cracked a big one: they’ve figured out how to use everyday sunlight to create entangled photons—those ultra-linked quantum particles—without needing expensive, power-hungry lasers. By focusing sunlight through a custom cone-shaped device into a crystal, researchers from the University of Ottawa and Max Planck Institute achieved 94% accurate entanglement over three days. While clouds and optical distortions hurt performance, this proof-of-concept opens the door to solar-powered quantum tech—think satellites generating secure encryption or quantum computers that run on sunshine…
