Researchers Control the Flip of Electron Spin

Posted by Zonk on from the wheeee dept.

karvind writes "According to PhysOrg, physicists in Europe, California and at Ohio University now have found a way to manipulate the spin of an electron with a jolt of voltage from a battery. In this experiment voltage was applied to Indium Arsenide based quantum dot which flipped the spin of electron inside it and emitted a photon. The scientists were able to manipulate how long it would take for the electron to flip its spin and emit a photon - from one to 20 nanoseconds. This may have possible applications in optoelectronics and quantum cryptography. Results were published in the latest issue of Physics Review Letters"

    I think I am going to flip if I don't get an extra JOLT of caffene!

    It seems like this is just a small-scale example of effects like this, where the whole planet does a whoopsie.
    Seems like a step in the direction of understanding gravity.
    Let's fund this kind of research, shall we?

    According to ancient Chinese folk lore you're very complimentary toward Jews. The reasoning is, hatred being self consuming, pays the compliment to the focus of your hatred as being worthy of consumming your life. I think in return they don't think you're worth the cost.

    This electron spin technology should be designated "top secret". If the Chinese ever access this technology (or, more likely, steal it), then Beijing could significantly enhance the communications technology of its military.

    We must be careful.

    I'm like to know who moderated the first post as redundant.
