Theory of quantum optical control of a single spin in a quantum dot

Year: 2004

Type: article

Abstract: We present a theory of quantum optical control of an electron spin in a single semiconductor quantum dot via spin-flip Raman transitions. We show how an arbitrary spin rotation may be achieved by virtual excitation of discrete or continuum trion states. The basic physics issues of the appropriate adiabatic optical pulses in a static magnetic field to perform the single-qubit operation are addressed.
