摘要
Various methods of all-optical spin control in semiconductor quantum dots are discussed, and different ways of rotating a single confined electron spin by optical coupling to a trion state are presented in the paper. A method for controlling the polarization of a confined exciton via a two-photon transition is also discussed. Finally, the effect of phonon-induced decoherence on the fidelity of these optical spin control protocols is analysed.
