Design and Characterization of a Monolithic Three-Dimensional Ion Trap

Trapped ions are a leading platform of quantum computation and quantum simulation. Innovations in ion trap architecture in recent years have led to the scaling up, and improved performances of trapped ion quantum devices. A three-dimensional (3D) ion trap benefits from deep and symmetric trapping potentials, low heating rates, and good shielding from stray electric fields. In this work, we present a novel monolithic 3D ion trap microfabricated from a single piece of fused silica, developed in collaboration with Translume Inc and Rice University. The segmented blades are precisely machined to produce a homogeneous trapping potential along the center axis of the trap. We characterize the trap performance. We also discuss the applications of the trap and future upgrades to the trap design.
