We present a theory of the optical control of the spin of an electron in an InAs quantum dot. We show how two Raman-detuned laser pulses can be used to obtain arbitrary single-qubit rotations via the excitation of an intermediate trion state. Our theory takes into account a finite in-plane hole g-factor and hole mixing. We show that such rotations can be performed to high fidelities with pulses lasting a few tens of picoseconds.
