The research, a collaboration between teams led by Professor Halina Rubinsztein-Dunlop at the University of Queensland (UQ) and Nobel Laureate William Phillips at the US National Institute of Standards and Technology , was recently published in Nature . The scientists used ultracold temperatures, laser beams and magnetic fields to produce atoms Read More Go to Site

		Quantum Computation. Mini-Course ^Votes:0 Quantum Computation. Mini-Course Andr? Berthiaume January 1996 Abstract: Computer science has a classical soul; many definitions implicitly contain ideas from the time we believed the world evolved according to newtonian physics. Ideas such as: an object's state is well defined, instantaneous actions at a distance are impossible, etc. Modern physics and more specifically quantum physics tells us that Nature is not as straightforward as Newton originally believed. One can prepare systems such that the state is completely undefined in any classical sense. Instantaneous actions at a distance have been observed and sometimes having less alternatives to produce a given outcome may improve the probability of getting this outcome! What would happen computing models are allowed to operate within t Read More Go to Site

		Quantum computation: a tutorial ^Votes:0 Next: Computing at the atomic scale Quantum computation: a tutorial Samuel L. Braunstein Abstract: Imagine a computer whose memory is exponentially larger than its apparent physical size; a computer that can manipulate an exponential set of inputs simultaneously; a computer that computes in the twilight zone of Hilbert space. You would be thinking of a quantum computer. Relatively few and simple concepts from quantum mechanics are needed to make quantum computers a possibility. The subtlety has been in learning to manipulate these concepts. Is such a computer an inevitability or will it be too difficult to build? In this paper we give a tutorial on how quantum mechanics can be used to improve computation. Our challenge: solving an exponentially difficult problem for a conventional computer Read More Go to Site

Previous: quantum bogodynamics Next: quantum computing quantum computer < computer > A type of computer which uses the ability of quantum systems, such as a collection of atoms, to be in many different states at once. In theory, such superpositions allow the computer to perform many different computations simultaneously. This capability is combined with interference among the states to produce answers to some problems, such as factoring integers, much more rapidly than is possible with conventional computers. In practice, such machines have not yet been built due to their extreme sensitivity to noise. Oxford University , Stanford University . A Read More Go to Site

		Quantum Computers Leap From Theory to a Powerful Potential ^Votes:0 April 28, 1998 Quantum Computers Leap From Theory to a Powerful Potential By JOHN MARKOFF AN FRANCISCO -- Scientists have seen the future of computing in a thimbleful of chloroform. Researchers at IBM Corp., the Massachusetts Institute of Technology, the University of California at Berkeley and Oxford University earlier this month reported they have for the first time had succeeded in building the first working computers based on the principles of quantum mechanics, a branch of physics that describes the quirky world of subatomic particles where both yes and no can simultaneously be true. Illustration: Stuart Goldenberg In a long-sought breakthrough, the scientists were able to fashion a novel computer in which the processor consisted of atoms of hydrogen and chlorine and used it to sort a Read More Go to Site

		Simulation hints at quantum computer power TRN 050201 ^Votes:0 Introducing a monthly newsletter from the editors of TRN - the latest on the littlest Simulation hints at quantum computer power By Eric Smalley, Technology Research News Planning the best route to take for, say, running errands seems like a fairly simple problem. But the number of possibilities increases exponentially with each additional destination. For 15 destinations there are billions of possible routes. To make matters worse, there are no known mathematical shortcuts for finding the most efficient route. Solving the problem means comparing every route. "The number of possibilities with 500 [destinations] is huge. It's more than astronomically big," said Edward Farhi, a professor of physics at the Massachusetts Institute of Technology.
