利用平滑准方波脉冲实现鲁棒量子控制

Robust quantum control by smooth quasi-square pulses

Jing-jun Zhu, Xavier Laforgue, Xi Chen, Stéphane Guérin

摘要:

已知鲁棒时间最优控制以恒定(方)脉冲为特征。我们分析快速绝热动力学,保持鲁棒性,通过使用替代平滑准方脉冲,通常由超高斯脉冲表示。我们在这里考虑两个协议,鲁棒的逆优化和时间收缩绝热通道,允许在这两种情况下设计相同的脉冲形状。动力学和他们的性能进行了比较。证明了前一种协议的优越性。

英文摘要:

Robust time-optimal control is known to feature constant (square) pulses. We analyze fast adiabatic dynamics that preserve robustness by using alternative smooth quasi-square pulses, typically represented by hyper-Gaussian pulses. We here consider the two protocols, robust inverse optimization and time-contracted adiabatic passage, allowing the design of the same pulse shape in both cases. The dynamics and their performance are compared. The superiority of the former protocol is shown.
