New Step Towards Quantum Computers

The intrinsic rotation of electrons -- the "spin" -- is a promising property for future electronics devices. If use as an information carrier were possible, the processing power of electronic components would suddenly increase to a multiple of the present capacity. Physicists have now succeeded in aligning electron spin, bringing it to a controlled "waver" and reading it out. The electron spin can also be realigned as required at any time using optical pulses.
