Distance scaling and polarization of electric-field noise in a surface ion trap
Da An, Clemens Matthiesen, Erik Urban +1
We probe electric-field noise in a surface ion trap for ion-surface distances between 50 and 300 in the normal and planar directions. We find the noise distance d…

Coherent Control of the Rotational Degree of Freedom of a Two-Ion Coulomb Crystal
Erik Urban, Neil Glikin, Sara Mouradian +3
We demonstrate the preparation and coherent control of the angular momentum state of a two-ion crystal. The ions are prepared with an average angular momentum of freely…

Surface trap with dc-tunable ion-electrode distance
Da An, Clemens Matthiesen, Ahmed Abdelrahman +5
We describe the design, fabrication, and operation of a novel surface-electrode Paul trap that produces a radio-frequency-null along the axis perpendicular to the trap surface. Thi…
