Molecular Beam Setup for Quantum Logic Spectroscopy of single Molecular Ions — •Jan Christoph Heip1, Fabian Wolf1, Chunyan Shi1, and Piet O. Schmidt1,2 — 1Physikalisch-Technische Bundesanstalt, Braunschweig, Germany — 2Institut für Quantenoptik, Leibniz Universität Hannover, Germany
Molecular ions have a rich level structure and therefore are useful for applications ranging from precision measurements to quantum information processing. Besides the motional degrees of freedom, they exhibit also vibrational and rotational degrees of freedom, rendering direct laser cooling a challenge. We have demonstrated non-destructive rotational state detection and quantum logic spectroscopy in MgH+ using a co-trapped Mg+ logic ion [1]. Furthermore, we will present the design of an improved experimental setup including a molecular beam and an RF-Paul-trap with segemented blades. The molecular beam will enable the investigation of a large variety of molecular ions and significantly shorten the time required for preparing a single cold molecular ion.
