Multilayer ion trap for scalable quantum simulation and quantum information processing — •Giorgio Zarantonello1,2, Henning Hahn1,2, Sebastian Grondkowski1, Timko Dubielzig1, Fabian Ude1, Martina Wahnschaffe1,2, Amado Bautista-Salvador1,2, and Christian Ospelkaus1,2 — 1Institut für Quantenoptik, Leibniz Universität Hannover, Welfengarten 1, 30167 Hannover — 2PTB, Bundesallee 100, 38116 Braunschweig
Based on recent advances in surface-electrode trap fabrication in our group, we present a novel trap design with embedded multi-layer waveguides to implement quantum control using the microwave near-field gradient approach [1-3]. This new multilayer trap represents a significant development from the previous generations in terms of both scalability and performance. We will present the main results from the finite element simulations of the microwave near-fields and compare it with the previous single-layer design [4]. The new room temperature experimental setup housing the trap structure will also be presented.
