论文摘要
我们提出的方案是在谐波陷阱中制备被困离子的高度激发能量本质状态，这不需要激光脉冲来诱导内部水平之间的过渡。相反，协议依赖于单个井配置和双井配置之间的陷阱势。设置变化的速度是通过保持绝热参数恒定来最大程度地减少非绝热过渡。在控制参数的线性斜坡上，发现高忠诚度的时间高两个以上的数量级以上。还设计了变形方案来制备叠加，以优化干涉敏感性，结合基态和高度激发的状态。
We propose protocols to prepare highly excited energy eigenstates of a trapped ion in a harmonic trap which do not require laser pulses to induce transitions among internal levels. Instead the protocols rely on smoothly deforming the trapping potential between single and double well configurations. The speed of the changes is set to minimize non-adiabatic transitions by keeping the adiabaticity parameter constant. High fidelities are found for times more than two orders of magnitude smaller than with linear ramps of the control parameter. Deformation protocols are also devised to prepare superpositions to optimize interferometric sensitivity, combining the ground state and a highly excited state.
