Since there was no way for the photons to communicate with each other, ''classical'' physics would predict that their independent choices would bear no relationship to each other. Reaching the ends of these fibers, the two photons were forced to make random choices between alternative, equally possible pathways. Gisin sent pairs of photons in opposite directions to villages north and south of Geneva along optical fibers of the kind used to transmit telephone calls. Nicolas Gisin of the University of Geneva and his colleagues last month was the most spectacular demonstration yet of the mysterious long-range connections that exist between quantum events, connections created from nothing at all, which in theory can reach instantaneously from one end of the universe to the other. IT was as if some ghostly bridge across the city of Geneva, Switzerland, had permitted two photons of light nearly seven miles apart to respond simultaneously to a stimulus applied to just one of them.
