Towards the implementation of microwave near-field entangling gates in a cryogenic surface-electrode ion trap apparatus — •Niklas Orlowski1, Chloë Allen Ede1, Niels Kurz1, Sebastian Halama1, Timko Dubielzieg1, Celeste Torkzaban1, and Christian Ospelkaus1,2 — 1Institut für Quantenoptik, Leibniz Universität Hannover, 30167 Hannover, Germany — 2Physikalisch Technische Bundesanstalt, 38116 Braunschweig, Germany
We discuss ion loading using different lasers for the ablation, ionization, cooling and detection of Beryllium ions and describe measures taken to isolate ions from environmental influences, for example by using vibrational decoupling, electromagnetic shielding, and an XUHV-environment [1]. We demonstrate hyperfine state preparation and manipulation with microwave pulses and discuss requirements on radial mode stability for the implementation of entangling microwave quantum gates [2].
