Towards quantum control of Calcium ions for the use in molecular spectroscopy — •Manika Bhardwaj, Josselin Bernardoff, Jan Thieme, Daqing Wang, Markus Debatin, and Kilian Singer — University of Kassel, Kassel, Germany

We present our advances towards establishing a new two- dimensional spectroscopy method that selectively maps the suitable quantum states. For this purpose, the molecular ions to be investigated are sympathetically cooled and trapped in an ion trap with laser-cooled calcium ions [1]. We will use the photon-recoil spectroscopy method to study the molecular ions through studying the photon-recoil imparted on co-trapped calcium ion [2].
