Abstract
A vacuum cell provides for electric field control within an ultra-high vacuum (UHV) for cold-neutral-atom quantum computing and other quantum applications. Electrode assemblies extend through vacuum cell walls. Prior to cell assembly, contacts are bonded to respective locations on the ambient-facing surfaces of the walls. Trenches are formed in the vacuum-facing surfaces of walls and via holes are formed, extending from trenches through the wall and into the contacts. Plating conductive material into the trenches and via holes forms the electrodes and vias. The electrodes are contained by the trenches and do not extend beyond the trenches so as to avoid interfering with the bonding of components to the vacuum-facing surfaces of the walls. The vias extend into the contacts to ensure good electrical contact. An electric-field controller applies electric potentials to the electrodes (via the contacts) to control electric fields within the vacuum.
