ScienceDaily (June 7, 2012) The quantum computer is a futuristic machine that could operate at speeds even more mind-boggling than the world's fastest super-computers. <\/p>\n
Research involving physicist Mike Thewalt of Simon Fraser University offers a new step towards making quantum computing a reality, through the unique properties of highly enriched and highly purified silicon. <\/p>\n
Quantum computers right now exist pretty much in physicists' concepts, and theoretical research. There are some basic quantum computers in existence, but nobody yet can build a truly practical one -- or really knows how. <\/p>\n
Such computers will harness the powers of atoms and sub-atomic particles (ions, photons, electrons) to perform memory and processing tasks, thanks to strange sub-atomic properties. <\/p>\n
What Thewalt and colleagues at Oxford University and in Germany have found is that their special silicon allows processes to take place and be observed in a solid state that scientists used to think required a near-perfect vacuum. <\/p>\n
And, using this 28Si they have extended to three minutes -- from a matter of seconds -- the time in which scientists can manipulate, observe and measure the processes. <\/p>\n
\"It's by far a record in solid-state systems,\" Thewalt says. \"If you'd asked people a few years ago if this was possible, they'd have said no. It opens new ways of using solid-state semi-conductors such as silicon as a base for quantum computing. <\/p>\n
\"You can start to do things that people thought you could only do in a vacuum. What we have found, and what wasn't anticipated, are the sharp spectral lines (optical qualities) in the 28Silicon we have been testing. It's so pure, and so perfect. There's no other material like it.\" <\/p>\n
But the world is still a long way from practical quantum computers, he notes. <\/p>\n
Quantum computing is a concept that challenges everything we know or understand about today's computers. <\/p>\n<\/p>\n
