2010-06-29 23:13:37 - revision [ Version = 14 --> Version 15 ] by bci1 ''Quantum computing: No turning back March 15, 2005 The first realizations of 'cluster states' and cluster-state quantum computation are reported in Nature this week (10 March issue, pp169-176). This represents a significant move from theory to reality for an alternative approach to quantum computing first proposed in 2001. Ads by Google The Nanotech Revolution - Long Overdue, Nanotech Is About to Make It Big. Free Investing Report. - www.wealthdaily.com/Nanotech Anton Zeilinger and colleagues (University of Vienna, Austria) take Robert Raussendorf and Hans Briegel’s ideas for computing, based on highly entangled clusters of many particles - in this case photons - and demonstrate that modifications to the entangled photons in such a state allows them to perform certain computing tasks. The entangled photons allow the system to encode information before computations begin and imprint a quantum logic circuit on the state, destroying its entanglement and making the process irreversible. Hence the name ‘one-way quantum computing’ for the system. This article reports the first experimental demonstration of the one-way quantum computer, which radically changes how we think about quantum physics and opens up exciting possibilities for the experimental implementation of quantum computation."
