论文摘要
我们引入了一种方法，以任意旋转通用宽带复合脉冲序列的激发曲线，以实现强大的高保真种群反演。这些脉冲可以补偿任何实验参数（例如脉冲振幅，脉冲持续时间，引起共振，鲜明的偏移，不需要的频率响声等）的偏差，并且适用于任何脉冲形状。旋转可以使脉冲区域的任何组合并以无需额外的费用实现更高阶的鲁棒性。后者可能特别有用，例如，当误差引起的较为偏移时，与所施加场的功率相关。我们通过实现$ \ text {pr}^{3+} {3+} \ text {：} \ text {y} _2 _2 \ text {sio} {sio} {sio} _5 \ \：$ crystal。
We introduce a method to rotate arbitrarily the excitation profile of universal broadband composite pulse sequences for robust high-fidelity population inversion. These pulses compensate deviations in any experimental parameter (e.g. pulse amplitude, pulse duration, detuning from resonance, Stark shifts, unwanted frequency chirp, etc.) and are applicable with any pulse shape. The rotation allows to achieve higher order robustness to any combination of pulse area and detuning errors at no additional cost. The latter can be particularly useful, e.g., when detuning errors are due to Stark shifts that are correlated with the power of the applied field. We demonstrate the efficiency and universality of these composite pulses by experimental implementation for rephasing of atomic coherences in a $\text{Pr}^{3+}\text{:}\text{Y}_2\text{SiO}_5\:$ crystal.
