Popis: We report coherent optical control of a single hole spin confined to an InAs/GaAs quantum dot. The hole spin was initialized by fast dissociation of a spin-polarized electron-hole pair, and controlled by combining coherent rotations about two perpendicular axes: Larmor precession about an external Voigt-geometry magnetic field, and optical rotation caused by the geometric phase shift induced by a picosecond laser pulse.
