  • One Electron At A Time: Scientists Close In On Quantum Computing
    August 21, 2008 – 12:50 PM
    Researchers at the University of Michigan, U.S. Naval Research Laboratory and the University of California at San Diego have made a big step towards quantum computing by trapping the spin of one electron in critical dark state - at rates of about 1 GHz.
  • Experts doubt quantum computer's authenticity
    February 15, 2007 – 7:30 PM
    D-Wave's quantum computer demonstration this week has generated lots of buzz, but some experts doubt the authenticity of the demo. At the Computer History Museum in Mountain View California, company reps solved Sudoku problems and calculated seating plans, but some university researchers and corporate scientists need to see more data to be convinced. They are also concerned about D-Wave's lack of peer research and of the test's remote nature.
  • New kind of quantum computer moves closer
    November 20, 2006 – 7:02 PM
    A U.S. physicist has shown it is feasible to read data stored in the magnetic 'spins' of phosphorus atoms - a step toward creating a superfast computer.
  • Quantum computer works best switched off
    February 23, 2006 – 11:40 AM
    Even for the crazy world of quantum mechanics, this one is twisted. A quantum computer program has produced an answer without actually running.
  • Quantum attacks worry computer scientists
    November 3, 2006 – 4:54 PM
    In the weird world of quantum computing, the state of computer systems networked together is so fragile that a read access to a single quantum bit, or qubit, on one machine would require a network-wide reset.
  • Quantum effect offers molecular transistors
    September 8, 2006 – 2:57 PM
    A molecular switch that operates in a fundamentally new way could usher in a generation of microprocessors that work on the molecular scale.
  • AIST develops optical control device structure for quantum computers
    December 19, 2005 – 7:00 PM
    The Ultrafast Optoelectronic Devices Group of the Photonics Research Institute of the National Institute of Advanced Industrial Science and Technology (AIST) has developed a basic structure of an optical control device for use in quantum computers.
  • 'Electron-spin' trick boosts quantum computing
    August 16, 2006 – 3:43 PM
    A new silicon chip capable of manipulating the spin of a single electron could ultimately allow futuristic quantum computers to be built using conventional electronic technology, researchers say.
  • Nanomechanical device bridges classic and quantum physics
    February 9, 2005 – 6:05 PM
    Nanotechnology leapt into the realm of quantum mechanics this past winter when an antenna-like sliver of silicon one-tenth the width of a human hair oscillated in a lab in a Boston University basement.
  • Scientists find flaw in quantum dot construction
    February 13, 2005 – 12:06 PM
    Nanoscientists dream of developing a quantum computer, a device the size of a grain of sand that could be faster and more powerful than today's PCs.
  • University of Michigan develops quantum processor
    January 17, 2006 – 3:42 PM
    It's much too early for AMD or Intel to start looking over their shoulder, but the University of Michigan has developed a quantum chip that contains one cadmium ion. The ion, which is suspended in electrical fields, can exist in many possible states which collapse into one when viewed by an outsider. Quantum computing has been touted as great leap in computing, but still faces many challenges.
  • Quantum quest leads to super-efficient lights
    April 13, 2006 – 2:40 PM
    A light that lasts 20 times longer than a conventional bulb and is 75% more energy efficient has been developed by researchers.
