Ablation Loading and Tuning Techniques for the electrical potential in Surface-Electrode Ion Traps — •Leonard Nitzsche, Frederick Hakelberg, Philip Kiefer, Henning Kalis, Ulrich Warring, and Tobias Schaetz — Atom-, Molekül- und optische Physik, Physikalisches Institut, Albert-Ludwigs-Universität, Freiburg, Hermann-Herder-Str. 3, 79104 Freiburg

Precise and individual control of motional degrees of freedom of trapped ions is needed for the advent of larger scale quantum simulations and computations in microfabricated trap arrays. Key techniques include, e.g., reduction of aging effects such as contamination of the trap surfaces as well as tuning of mirco potentials adressing single ions without affecting the overall performance of the array. Here we present preliminary results in optimising laser ablation loading of Mg⁺ and shaping the trap potential adressing individual ions via control potentials up to the fourth order.
