Abstract
Optically induced spin dynamics are considered in a system of two localized spins (two-bit system) embedded in a semiconductor host. Through a nonperturbative treatment, an intense off-resonant laser radiation is found to induce an oscillation of the spin exchange synchronized by the Rabi oscillation of virtual excitons in the host. This is a direct consequence of oscillating quantum phases of virtual exciton states under Rabi oscillation and can be used as a new mechanism to control spin states with respect to externally controlled parameters-laser energy and laser intensity.
