Optimization methods for RF junctions in register-based surface-electrode ion traps — •Florian Ungerechts1, Rodrigo Munoz1, Axel Hoffmann1,2, Brigitte Kaune1, Teresa Meiners1, and Christian Ospelkaus1,3 — 1Institut für Quantenoptik, Leibniz Universität Hannover, Welfengarten 1, 30167 Hannover, Germany — 2Institut für Hochfrequenztechnik und Funksysteme, Leibniz Universität Hannover, Appelstraße 9a, 30167 Hannover, Germany — 3Physikalisch-Technische Bundesanstalt, Bundesallee 100, 38116 Braunschweig, Germany
Register-based ion traps are among the leading approaches for scalable quantum processors. A fundamental component of these are RF junctions that allow the ions to move between the specialized zones of the quantum processor via ion transport. We discuss the design choices and optimization methods of such a junction and present an optimized symmetric RF X-junction feasible for through-junction ion transport of single 9Be+ ions and multilayer microfabrication.
