Towards low motional heating of surface trap with in-situ argon treatment

Surface Paul traps suffer from excessive electric field noise which limits single and multi qubit gate fidelities. While the physical mechanism for this heating is still under extensive research it has been shown that surface treatment using ion bombardment can reduce this effect by two orders of magnitude. In this work we have built a vacuum setup that is compatible with the HOA-2.1 surface trap from Sandia National Laboratory and have characterized the trap at room temperature with Ca ions. In addition, we have the ability for in-situ treatment of the surface. We believe that this treatment capability will enable manipulating larger quantum systems in room temperature surface traps.
