ScienceDaily (Apr. 19, 2012) — Using lasers to excite just one atom from a cloud of ultra-cold rubidium gas, physicists have developed a new way to rapidly and efficiently create single photons for potential use in optical quantum information processing -- and in the study of dynamics and disorder in certain physical systems.http://www.sciencedaily.com/releases/2012/04/120419143113.htm
