    "abstract": "Electron spin coherence has been generated optically in n-type modulation\ndoped (In,Ga)As/GaAs quantum dots (QDs) which contain on average a single\nelectron per dot. The coherence arises from resonant excitation of the QDs by\ncircularly-polarized laser pulses, creating a coherent superposition of an\nelectron and a trion state. Time dependent Faraday rotation is used to probe\nthe spin precession of the optically oriented electrons about a transverse\nmagnetic field. Spin coherence generation can be controlled by pulse intensity,\nbeing most efficient for (2n+1)pi-pulses.",
