Physicists Get a Grip on a Single Electron's Spin

Facebook X LinkedIn Email
DELFT, Netherlands, Aug. 28, 2006 -- For the first time, researchers said they have succeeded in controlling the spin of a single electron in a nanostructure. The achievement is a step toward using the electron's spin as a quantum bit, the basis for constructing a still-theoretical quantum computer.

    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.
    quantum mechanics
    The science of all complex elements of atomic and molecular spectra, and the interaction of radiation and matter.
    spin
    Acronym for self-aligned polysilicon interconnect N-channel. A metal-gate process that uses aluminum for the metal-oxide semiconductor (MOS) gate electrode as well as for signal and power supply connectors.
