Spin degree of freedom of localized carriers isconsidered as a candidate for implementation
of a quantum bit (qubit). The strategies to realize the all-optical qubit initialization, readout and coherent control based on single carriers confined in semiconductor quantum dots are discussed. Further, we consider the two entangled quantum bits based on two vertically-stacked singly-charged quantum dots and demonstrate the realization of optical control for a single and two-qubit states.
