Stopping light could be a boon for quantum computing

Two teams of scientists have accomplished the seemingly impossible feat of trapping and stopping light--an achievement that could lead to major advances in quantum computing. The two teams--one from Harvard University and the other from the Rowland Institute of Science--brought light to a halt by shining a pulse of light into a chamber of gas in which the beam got slower and slower and dimmer and dimmer before coming to a stop.
