Towards large-scale microwave quantum devices with trapped ions — •Amado Bautista1,2, Henning Hahn1,2, Giorgio Zarantonello1,2, Jonathan Morgner1,2, and Christian Ospelkaus1,2 — 1Leibniz University of Hannover, Welfengarten 1, 30176 Hannover — 2Physikalisch-Technische Bundesanstalt, Bundesallee 100, 38116 Braunschweig
Currently quantum computing with trapped ions is reaching an unprecedented maturity towards a practical realization of a scalable platform. The field requires also a significant effort on reaching a scalable hardware. Here we present recent advances on the development of a novel method for the realization of large-scale quantum devices [1]. First, I will detail on the trap fabrication and show preliminary results on the characterization of a multilayer ion trap with integrated 3D microwave circuitry [2] towards the implementation of high-fidelity quantum logic control on 9Be+ ions. We demonstrate ion trapping, simple microwave control on a laser cooled 9Be+ ion held at a distance of 35 µm, characterize the magnetic field around the trap center based on our 2D near-field model [3]. Finally, I will discuss new routes and potential new integrated devices in which the multilayer method can be exploited.
