Hybrid Atom Identified

Facebook X LinkedIn Email
WEST LAFAYETTE, Ind., June 27, 2008 -- Experiments with nanoscale transistors by an international team have led to the identification of a hybrid atom that is half natural, half man-made and could be used to develop quantum computers. "Up to now large-scale quantum computing has been a dream," said Gerhard Klimeck, professor of electrical and computer engineering at Purdue University and associate director for technology for the National Network for Computational Nanotechnology. "This development may not bring us a quantum computer 10 years faster, but our dreams about these machines are now more realistic." An...Read full article

    Glossary
    electron
    A charged elementary particle of an atom; the term is most commonly used in reference to the negatively charged particle called a negatron. Its mass at rest is me = 9.109558 x 10-31 kg, its charge is 1.6021917 x 10-19 C, and its spin quantum number is 1/2. Its positive counterpart is called a positron, and possesses the same characteristics, except for the reversal of the charge.
    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
    quantum mechanics
    The science of all complex elements of atomic and molecular spectra, and the interaction of radiation and matter.
