Scientists from the Kavli Institute of Nanoscience at Delft University of Technology and Eindhoven University of Technology have succeeded in controlling the building blocks of a future super-fast quantum computer. They are now able to manipulate these building blocks (qubits) with electrical rather than magnetic fields, as has been the common practice up till now. They have also been able to embed these qubits into semiconductor nanowires. The scientists' findings have been published in the...

SAN JOSE, Calif., Dec. 23, 2010 /PRNewswire/ -- Highlights: IBM Research is the first to measure the movement and processing of digital data as a magnetic pattern on nanowires 1,000 times finer than a human hair. New memory uses the spin of electrons to move data at hundreds of miles per hour to atomically precise positions along the nanowire racetrack. This memory could someday enable a single portable device to store all the movies produced worldwide in a given year and run on a...

Researchers pave the way for spin computers A research team from the Institut Català de Nanotecnologia (ICN), in Barcelona, has demonstrated a device that induces electron spin motion without net electric currents, a key step in developing the spin computers of the future. The results are published in the Dec 17 issue of the journal Science. The authors are Marius V. Costache and Sergio O. Valenzuela, an ICREA Professor who is leader of the Physics and Engineering of...

With the help of neutrons, TUM physicists discover new ways to save data One of the requirements to keep trends in computer technology on track "“ to be ever faster, smaller, and more energy-efficient "“ is faster writing and processing of data. In the Dec. 17 issue of the journal Science, physicists at the Technische Universitaet Muenchen (TUM) and the Universitaet zu Koeln report results that could point the way to a solution. TUM physicists set a lattice of magnetic vortices in...

Physicists read data after storing them in atomic nuclei for 112 seconds University of Utah physicists stored information for 112 seconds in what may become the world's tiniest computer memory: magnetic "spins" in the centers or nuclei of atoms. Then the physicists retrieved and read the data electronically "“ a big step toward using the new kind of memory for both faster conventional and superfast "quantum" computers. "The length of spin memory we observed is more than adequate to...

US-European team revisits 30-year-old breakthrough with new methods, understanding European and U.S. physicists this week are offering up the strongest evidence yet that magnetism is the driving force behind unconventional superconductivity. The findings by researchers from Rice University, the Max Planck Institute for Chemical Physics of Solids (MPI-CPfS) in Dresden, Germany, and other institutions were published online today in Nature Physics. The findings follow more than three decades of...

Physicists at Ohio State University have discovered that tiny defects inside a computer chip can be used to tune the properties of key atoms in the chip. The technique, which they describe in the journal Science, involves rearranging the holes left by missing atoms to tune the properties of dopants "“ the chemical impurities that give the semiconductors in computer chips their special properties. Though the technique is currently limited to the laboratory, it could prove valuable to...

Researchers from Queen Mary, University of London (UK) and the University of Fribourg (Switzerland) have shown that a magnetically polarised current can be manipulated by electric fields. Published this week in the journal Nature Materials, this important discovery opens up the prospect of simultaneously processing and storing data on electrons held in the molecular structure of computer chips - combining computer memory and processing power on the same chip. "This is especially exciting, as...

Tracking down Cooper pairs: RUB researchers confirm theoretical hypothesis The results achieved by this research team headed by Prof. Kurt Westerholt and Prof. Hartmut Zabel (Department of Physics and Astronomy at RUB) could contribute to new, power saving components in the future. The researchers reported on their findings in the American Physical Society's noted journal "The Physical Review". Electron pairs in singlet state If it were possible to eliminate electrical resistance we could...
