我们引入了通用宽带复合脉冲序列，用于两态量子系统的鲁棒高保真人口反转，它补偿驱动场的任何参数的偏差（例如，脉冲幅度，脉冲持续时间，共振失谐，斯塔克位移，不必要的频率啁啾等），并且适用于任何脉冲形状。我们用Pr3+:Y2SiO5晶体中原子相干重相位的实验数据证明了这些复合脉冲的有效性和普适性。
We introduce universal broadband composite pulse sequences for robust high-fidelity population inversion in two-state quantum systems, which compensate deviations in any parameter of the driving field (e.g., pulse amplitude, pulse duration, detuning from resonance, Stark shifts, unwanted frequency chirp, etc.) and are applicable with any pulse shape. We demonstrate the efficiency and universality of these composite pulses by experimental data on rephasing of atomic coherences in a Pr3+:Y2SiO5 crystal.
