Quantum tricks drive magnetic switching into the fast lanedfsd
All-optical switching promises terahertz-speed hard drive and RAM memory.

Researchers at the U.S. Department of Energy's Ames Laboratory, Iowa State University, and the University of Crete in Greece have found a new way to switch magnetism that is at least 1000 times faster than currently used in magnetic memory technologies. Magnetic switching is used to encode information in hard drives, magnetic random access memory and other computing devices. The discovery, reported in the April 4 issue of Nature, potentially opens the door to terahertz (10^12 hertz) and faster memory speeds.
