离子阱中的双模相互作用

Engineering two-mode interactions in ion traps

J. Steinbach, J. Twamley, P. L. Knight

摘要:

我们描述了如何两个振动自由度的一个单一的被困离子可以耦合通过适当选择的激光激发的行动。我们集中在一个二维的离子阱与不同的振动频率在x和y方向的运动,并从第一原理推导出各种量化的双模耦合,集中在一个线性耦合,从一个模式到另一个激发。我们演示了这如何导致状态旋转,其中可以将离子的运动状态从x方向转移到y方向,而无需事先了解该运动状态。

英文摘要:

We describe how two vibrational degrees of freedom of a single trapped ion can be coupled through the action of suitably-chosen laser excitation. We concentrate on a two-dimensional ion trap with dissimilar vibrational frequencies in the x- and y-directions of motion, and derive from first principles a variety of quantized two-mode couplings, concentrating on a linear coupling which takes excitations from one mode to another. We demonstrate how this can result in a state rotation, in which it is possible to transfer the motional state of the ion from say the x-direction to the y-direction without prior knowledge of that motional state.
