http://technology.newscientist.com/article/mg19526216.700 By Saswato Das 13 September 2007 Magazine issue 2621 IT MIGHT seem like an esoteric achievement of interest to only a handful of computer scientists, but the advent of quantum computers that can run a routine called Shor's algorithm could have profound consequences. It means the most dangerous threat posed by quantum computing - the ability to break the codes that protect our banking, business and e-commerce data - is now a step nearer reality. Adding to the worry is the fact that this feat has been performed by not one but two research groups, independently of each other. One team is led by Andrew White at the University of Queensland in Brisbane, Australia, and the other by Chao-Yang Lu of the University of Science and Technology of China, in Hefei. Both groups have built rudimentary laser-based quantum computers that can implement Shor's algorithm - a mathematical routine capable of defeating today's most common encryption [...] ____________________________________ Visit the InfoSec News Bookstore http://www.shopinfosecnews.org
