Coherent control in quantum open systems: An approach for accelerating dissipation-based quantum state generation

摘要

In this paper, we propose an approach to accelerate the dissipation dynamicsfor quantum state generation with Lyapunov control. The strategy is to addtarget-state-related coherent control fields into the dissipation process tointuitively improve the evolution speed. By applying the current approach,without losing the advantages of dissipation dynamics, the target stationarystates can be generated in a much shorter time as compared to that viatraditional dissipation dynamics. As a result, the current approach containingthe advantages of coherent unitary dynamics and dissipation dynamics allows forsignificant improvement in quantum state generation.
