Rice physicists: Odd electron mix has fault-tolerant quantum registry HOUSTON -- There are enticing new findings this week in the worldwide search for materials that support fault-tolerant quantum computing. New results from Rice University and Princeton University indicate that a bizarre state of matter that acts like a particle with one-quarter electron charge also has a "quantum registry" that is immune to information loss from external perturbations.The research appeared...

An experiment led by a University of Alberta researcher, at the Large Hadron Collider (LHC) at CERN, could dramatically change our concepts of basic physics, revolutionize our understanding of the Universe and could eventually lead to technologies in future generations that right now only exist in science fiction.U of A physics professor James Pinfold is leading an international team of physicists who will use ultra high energy proton collisions. The protons will move at very near the speed...

Physicists at JILA have for the first time observed chemical reactions near absolute zero, demonstrating that chemistry is possible at ultralow temperatures and that reaction rates can be controlled using quantum mechanics, the peculiar rules of submicroscopic physics.The new results and techniques, described in the Feb. 12 issue of Science,* will help scientists understand previously unknown aspects of how molecules interact, a key to advancing biology, creating new materials, producing...

Hidden symmetry observed for the first time in solid state matterResearchers from the Helmholtz-Zentrum Berlin für Materialien und Energie (HZB), in cooperation with colleagues from Oxford and Bristol Universities, as well as the Rutherford Appleton Laboratory, UK, have for the first time observed a nanoscale symmetry hidden in solid state matter. They have measured the signatures of a symmetry showing the same attributes as the golden ratio famous from art and architecture. The research...

Quantum physicists simulate Dirac equation, 1 of the cornerstones in physicsResearchers of the Institute for Quantum Optics and Quantum Information (IQOQI) in Innsbruck, Austria, used a calcium ion to simulate a relativistic quantum particle, demonstrating a phenomenon that has not been directly observable so far: the Zitterbewegung. They have published their findings in the current issue of the journal Nature.In the 1920s quantum mechanics was already established and in 1928 the British...

DARPA to provide funding to quell Casimir forceScientists at the U.S. Department of Energy's Argonne National Laboratory are developing a way to control the Casimir force, a quantum mechanical force, which attracts objects when they are only hundred nanometers apart."The Casimir force is so small that most experimentation has dealt simply with its characteristics," said Derrick Mancini, interim director of the Center for Nanoscale Materials. "If we can control this force or...

Research team discovers a new use for metamaterials that promises to eliminate mechanical friction in nanotechnologyNanoscale machines expected to have wide application in industry, energy, medicine and other fields may someday operate far more efficiently thanks to important theoretical discoveries concerning the manipulation of famous Casimir forces that took place at the U.S. Department of Energy's Ames Laboratory.The groundbreaking research, conducted through mathematical simulations,...

Achieving an important new capability in ultracold atomic gases, researchers at the Joint Quantum Institute, a collaboration of the National Institute of Standards and Technology (NIST) and the University of Maryland, have created "synthetic" magnetic fields for ultracold gas atoms, in effect "tricking" neutral atoms into acting as if they are electrically charged particles subjected to a real magnetic field. The demonstration, described in the latest issue of the journal...

Information field theory enables astronomers, medical practitioners and geologists to look into places where their measuring instruments are blindA bit of imagination on the part of a measuring instrument wouldn't be a bad thing. It could help to add data from areas where the instrument is unable to measure. However, it must do so constructively. In order to infer missing data in an astronomical measurement with more than just imagination, physicists at the Max Planck Institute for...

BETHLEHEM, Pa., Nov. 10 /PRNewswire/ -- Particle Sciences Inc., a leading pharmaceutical CRO, has further expanded their capabilities by the acquisition of additional space bringing their total to approximately 21,000 sq ft. "Our current workload and existing pipeline simply necessitates this addition," says Dr. Mark Mitchnick, CEO. "2009 has been a record year for us and we have pretty good visibility on the next 12 months. The additional space will be used to expand our cGMP warehouse...
