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"

    Any news item that can be spun to be positive to the Jews, or negative to their enemies, is so spun.

    i read about this well over a year ago, in a computing magazine at that, and slashdot is just now showing the story? must not be enough "omg water is wet" stories out there today
