(American Chemical Society) Chinese researchers recently announced a landmark advancement: They used a satellite orbiting Earth to beam pairs of quantum-entangled photons to two Tibetan mountaintops more than 700 miles apart. This distance blew the previous record out of the water. But according to an article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, this is only the beginning for quantum communication.
