An integrated mirror and surface ion trap with a tunable trap location

We report a demonstration of a surfaceion trap fabricated directly on a highly reflectivemirror surface, which includes a secondary set of radio frequency (RF)electrodes allowing for translation of the quadrupole RF null location. We introduce a position-dependent photon scattering rate for a174Yb+ ion in the direction perpendicular to the trap surface using a standing wave of retroreflected light off themirror surface directly below the trap. Using this setup, we demonstrate the capability of fine-tuning the RF trap location with nanometer scale precision and characterize the charging effects of thedielectricmirror surface upon exposure to ultra-violet light.
