摘要
研究设计了一个有效的可扩展的二维刻槽离子芯片。为了减少激光在离子芯片表面的散射,使被囚禁离子更加稳定,并使激光容易控制和探测成行的被囚禁离子,在每两个平行的射频电极中间刻槽使冷却光和探测光路径可穿过芯片。把控制离子运动的直流电极跟射频电极分开,减轻了不同电压对被囚禁离子的干扰,改进了对离子的控制。用有限元分析的方法对芯片表面上方的电势分布做了计算模拟。模拟结果表明,在这种新型的刻槽可扩展芯片上可以生成一个可扩展的离子阱阵列。这种结构提供了一个新颖的刻槽二维平面离子芯片,被囚禁其上的线形离子阵列可用来进行大型的量子信息处理。
Abstract
We investigate an effective scalable grooved two-dimensional (2D) ion chip design. Grooves are cut between each two parallel radio frequency (RF) electrodes to decrease the laser scattering from ion chip surface, to easily open laser paths to control and to observe the strings of trapped ions. The control of ions has been improved by seperating direct current (DC) electrodes and RF electrodes. The potential distributions are calculated by using the finite element analysis method in order to verify the feasibility of our design. The results show that a scalable ion trap array still can be generated. Thus, this architecture provides a novel grooved 2D planar ion chip design and the arrays of trapped ions can be used in large-scale quantum information processing.
