本文报道了利用修饰自旋态进行绝热布居转移的理论研究。利用斩波随机基（CRAB）算法实现了耦合到强谐振微波场的带负电荷的金刚石氮空位中心的量子最优控制。我们表明，修饰自旋态是非常有效的抑制自旋退相绝热布居转移的影响。数值模拟还表明，基于CRAB的量子最优控制可以实现有效和鲁棒的绝热布居转移。
We report theoretical studies of adiabatic population transfer using dressed spin states. Quantum optimal control using the algorithm of Chopped Random Basis (CRAB) has been implemented in a negatively charged diamond nitrogen vacancy center that is coupled to a strong and resonant microwave field. We show that the dressed spin states are highly effective in suppressing effects of spin dephasing on adiabatic population transfer. The numerical simulation also demonstrates that CRAB-based quantum optimal control can enable an efficient and robust adiabatic population transfer.
