多态量子系统中无用跃迁路径的动力学抑制
Dynamical suppression of unwanted transition paths in multistate quantum systems
摘要：
我们介绍了一种方法来抑制不必要的过渡通道，即使不知道他们的耦合，并实现完美的人口转移在多态量子系统的应用程序的复合脉冲序列。不想要的过渡路径可能是由于不完善的光偏振，杂散电磁场，量子化轴的错位，空间不均匀性的捕获场，非共振耦合等。补偿偏振，脉冲面积，失谐的同时偏差证明。该技术的精确性、灵活性和鲁棒性使其适合于量子光学和量子信息处理中的高保真应用。
英文摘要：
We introduce a method to suppress unwanted transition channels, even without knowing their couplings, and achieve perfect population transfer in multistate quantum systems by the application of composite pulse sequences. Unwanted transition paths may be present due to imperfect light polarization, stray electromagnetic fields, misalignment of quantization axis, spatial inhomogeneity of trapping fields, off-resonant couplings, etc. Compensation of simultaneous deviations in polarization, pulse area, and detuning is demonstrated. The accuracy, the flexibility and the robustness of this technique make it suitable for high-fidelity applications in quantum optics and quantum information processing.
