Probing rotational decoherence with a trapped-ion planar rotor
Neil Glikin, Benjamin A. Stickler, Ryan Tollefsen +5
The quantum rotor is one of the simplest model systems in quantum mechanics, but only in recent years has theoretical work revealed general fundamental scaling laws for its decoher…
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…
