| Popis: | We discuss various methods of all-optical spin control in semiconductor quantum dots. We present different ways of rotating a single confined electron spin by optical coupling to a trion state. We also discuss a method for controlling the polarization of a confined exciton via a two-photon transition. Finally, we analyze the effect of phonon-induced decoherence on the fidelity of these optical spin control protocols. Comment: An introductory review paper, presented at the MAG-EL-MAT meeting 2007 |
