y By Iris Monica Vargas y Science News, Web edition : Monday, March 23rd, 2009 y Physicists have long thought that quantum entanglement, a mysterious link between separated particles that Einstein called “spooky action at a distance,” would allow quantum computers to solve certain hard math problems much faster than ordinary computers. But now it seems that entanglement can also be a nuisance. Instead of speeding up the process, too much entanglement can break down the entire system, researchers report in a paper to appear in Physical Review Letters . Entanglement occurs when quantum particles of energy or matter—such as atoms, ions or photons — interact, becoming intimately connected regardless of how far apart they later become. When two objects are entangled, their properties are mutually related. y “Consider two atoms,” says David Gross of Technical University of Braunschweig in Germany, lead author of the new paper. “We can think of a particle like an atom with tags identifying its properties saying, ‘I’m here,’ ‘I’m going in that direction at this speed.’ Now, if I have two or more atoms that have
