Scientists at UC Santa Barbara have devised a new type of superconducting circuit that behaves quantum mechanically -- but has up to five levels of energy instead of the usual two. The findings are published in the August 7 issue of Science. http://www.physorg.com/news169221847.html Physics Tue, 11 Aug 2009 15:04:34 EST news169221847 Substantial advances for applications of nanocrystals in the fields requiring a continuous output of photons and high quantum efficiency may soon be realized due to discovery of non-blinking semiconductor nanocrystals. This discovery recently announced by scientists at the Naval Research Laboratory (NRL), University of Rochester, Cornell University and Eastman Kodak Company is an important step to the use of the nanocrystals in various practical devices ranging from low-threshold lasers to the solar cells and biological imaging and tracking. The complete findings of the study are published on line in the May 10, 2009, issue of the journal Nature. http://www.physorg.com/news161536250.html Nanotechnology Thu, 14 May 2009 16:11:23 EST news161536250 (PhysOrg.com) -- MIT researchers may have found a way to overcome a key barrier to the advent of super-fast quantum computers, which could be powerful tools for applications such as code breaking. Ever since Nobel Prize-winning physicist Richard Feynman first proposed the theory of quantum computing more than two decades ago, researchers have been working to build such a device. http://www.physorg.com/news139665168.html Nanotechnology Wed, 03 Sep 2008 12:52:48 EST news139665168
