We present experimental work performed in a cryogenic apparatus exploiting a segmented-electrode ion trap architecture. This provides an ultra-high vacuum environment and fine control over the electric trapping potentials, allowing us to produce stable long linear ion strings.
A subset of up to ten ions are individually controlled by tightly focused laser beams perpendicular to the ion string axis providing reconfigurable optical tweezers and single ion addressing for quantum operations. We demonstrate engineering of the motional spectrum of long ion strings of up to a hundred 40Ca+ ions.
