用于里德伯原子数据寄存器相位恢复的最佳整形太赫兹脉冲

Optimally shaped terahertz pulses for phase retrieval in a Rydberg atom data register

C. Rangan, P. H. Bucksbaum

摘要:

我们采用最优控制理论,发现一个有效的信息检索算法,可以执行的里德伯原子数据寄存器使用整形太赫兹脉冲。该寄存器是一个Rydberg波包,其中一个组成轨道与其他组成轨道相位相反("标记位“)。执行解码算法的太赫兹脉冲通过将电子概率密度驱动到标记轨道中来实现。它的形状是通过修改最优控制问题的目标来计算的,这样它就代表了算法所有正确解的直积。

英文摘要:

We employ Optimal Control Theory to discover an efficient information retrieval algorithm that can be performed on a Rydberg atom data register using a shaped terahertz pulse. The register is a Rydberg wave packet with one consituent orbital phase-reversed from the others (the ``marked bit''). The terahertz pulse that performs the decoding algorithm does so by by driving electron probability density into the marked orbital. Its shape is calculated by modifying the target of an optimal control problem so that it represents the direct product of all correct solutions to the algorithm.
