    "abstract": "We study theoretically the quantum dynamics of an electron in the\nsingly-ionized double-donor structure in the semiconductor host under the\ninfluence of two strongly detuned laser pulses. This structure can be used as a\ncharge qubit where the logical states are defined by the lowest two energy\nstates of the remaining valence electron localized around one or another donor.\nThe quantum operations are performed via Raman-like transitions between the\nlocalized (qubit) states and the manyfold of states delocalized over the\nstructure. The possibility of realization of arbitrary single-qubit rotations,\nincluding the phase gate, the NOT gate, and the Hadamard gate, is demonstrated.\nThe advantages of the off-resonant driving scheme for charge qubit\nmanipulations are discussed in comparison with the resonant scheme proposed\nearlier.",
