RF junctions for register-based trapped-ion quantum processors — •Florian Ungerechts1, Rodrigo Munoz1, Janina Bätge1, Axel Hoffmann1,2, Teresa Meiners1, Brigitte Kaune1, 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
RF junctions are crucial for scaling trapped-ion quantum processors connecting the specialized zones in the QCCD architecture. We discuss the design and optimization techniques of such an RF junction for a surface-electrode trap, focusing on the implications for through-junction ion transport. We present an optimized RF X-junction feasible for the transport of single 9Be+ ions and multilayer microfabrication.
