βοΈ Scientists Generated Quantum Entanglement Using Just Sunlight β No Lasers Needed
Researchers just published a study in Optica showing that sunlight concentrated through a 1.4 square-meter solar collector into a nonlinear crystal produces quantum-entangled photon pairs with 94% fidelity β no energy-hungry lasers required. This challenges a core assumption in quantum tech: that lasers are indispensable for generating entangled photons. The approach could let satellites create secure encryption keys using ambient solar power, making space-based quantum networks far more practical. Could this be the breakthrough that finally scales quantum communication to the real world?
