摘要：AbstractThis paper introduces optimization technique to design the optical pulse sequence for the control of single spin dynamics in the Nitrogen-Vacancy color center, with controllable phase and optical rotation angle in different pulses. By repeatedly pumping the uncoupled ground state to the coupled excited states and dumping it back to the ground state, this method utilizes the rich interactions among the excited states to equivalently control the spin dynamics in the ground energy level. Based on the model identified in a recent experiment Bassett et al. (2014), numerical simulation shows that arbitrarily precise control of the spin dynamics can be achieved through our multi-optical-pulse control scheme, while the control speed is still kept at the nanosecond scale.
