Abstract
Several proposals for scalable quantum computation rely on the manipulation of the spin of individual electrons in semiconductors. We show that a spin-sensitive optical Stark effect will produce a coherent rotation of spin in quantum dots containing a single electron. The calculated magnitude of the effective magnetic field depends on the dot band gap and the strain. We predict that in

dots, for reasonable experimental parameters, the magnitude of the rotation is sufficient and the intrinsic error is low enough for them to serve as elements of a quantum-dot-based quantum computer.
