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"

    ...flipped the spin of electron inside it and emitted a photon...

    (IANA quantum physicist, but...) What if the unsuspecting electron is one of a correlated pair? When the flip occurs, does the sibling electron (perhaps a galaxy away) simultaneously flip... and maybe squirt a photon to dazzle some Arcturians?

    Ha, I first read this as "Researchers Control the Flip of Election Spin". I thought back to John Kerry and thought, hmmm, not a bad idea.

    Must be something very wrong with my faith in politics and politicians, since I've misread the title of the article as:

    Researchers control the flip of the election spin

    It took me a while to find out what is the idiom I don't know in this sentence, before I carefully read it again ;)))
