Abstract

Trapped ions are a leading system for implementing quantum information processing (QIP) on a small scale. A clear roadmap exists for achieving large scale QIP [1, 2] including the use of phase Fresnel lens (PFL) arrays as scalable optical interconnect [3]. Recently, we have demonstrated the successful integration of a single microfabricated PFL with an RF ion trap in UHV and in close proximity to the ions [4]. In that experiment, the image resolution was limited to about 4 µm by residual ion micromotion caused by the failure of the compensation electrodes. Here we present recent data of our system whereas micromotion is strongly suppressed by using DC fields to compensate for stray electric fields.
