囚禁离子中对称Dicke子空间的选择控制

Selective Control of the Symmetric Dicke Subspace in Trapped Ions

C. E. Lopez, J. C. Retamal, E. Solano

摘要:

提出了一种选择性操纵N个囚禁离子内部自由度对称Dicke子空间的方法。我们表明,直接访问离子运动子空间,基于一个适当的调整运动相关的AC斯塔克位移,诱导两个级别的动态,涉及先前选定的离子迪克状态。以这种方式,它是可能的,连续和单一的,离子迪克态与激发数增加。此外,我们提出了一个概率技术,直接产生任何离子迪克态假设合适的初始条件。

英文摘要:

We propose a method of manipulating selectively the symmetric Dicke subspace in the internal degrees of freedom of N trapped ions. We show that the direct access to ionic-motional subspaces, based on a suitable tuning of motion-dependent AC Stark shifts, induces a two-level dynamics involving previously selected ionic Dicke states. In this manner, it is possible to produce, sequentially and unitarily, ionic Dicke states with increasing excitation number. Moreover, we propose a probabilistic technique to produce directly any ionic Dicke state assuming suitable initial conditions.
