Microwave-driven quantum logic with trapped 9Be+ ions in microfabricated ion traps — •Jonathan Morgner1,2, Giorgio Zarantonello1,2, Henning Hahn1,2, Amado Bautista-Salvador1,2, and Christian Ospelkaus1,2 — 1Leibniz Universität Hannover, Germany. — 2Physikalisch-Technische Bundesanstalt, Braunschweig Germany.
Scalable quantum information processing relies on successful implementation of high-fidelity universal gate sequences. In this context, multi-qubit gates induced by microwave near-fields [1] provide a promising technique with potential for high fidelities [2].
Here we give a brief overview about our recent efforts to integrate microwave conductors in microfabricated traps to drive entangling gates on 9Be+ hyperfine qubits.
We further discuss benefits and future applications of a novel trap fabrication technique based on multiple metal layers. Additionally, we present a next generation vacuum setup utilizing Ar+ bombardement to clean the trap surfaces and thus, reduce gate errors caused by motional mode heating [3].
