Ordinary sunlight, it turns out, can entangle particles of light — a trick once taught only to lasers. Physicists obtained photon pairs with entanglement as good as lab-grade ones, allowing quantum devices to be powered directly by the sun, even on Mars.
🎯 Every second, the Sun radiates billions of times more light than needed to run all existing quantum networks.
🎬 Like in science fiction: a Martian colony might one day exchange entangled signals with Earth using nothing but daylight.
