Abstract in another language
In a single quantum dot doped with a single Mn atom, ultrafast optical control can be used to coherently manipulate the Mn spin state. Here we show that due to the optical Stark effect induced by a detuned laser pulse the Mn spin can be efficiently flipped by one during the action of the pulse. We discuss the influence of different pulse envelopes on the flipping process. We then show how this flipping mechanism can be used in a switching protocol to address all Mn spin states selectively and point out the advantage of exploiting the optical Stark effect compared to previously proposed methods.
