Towards Quantum Control of Calcium Ions for the use in Molecular Spectroscopy — •Manika Bhardwaj, Josselin Bernardoff, Jan Thieme, Daqing Wang, and Kilian Singer — Experimentalphysik I, Universität Kassel, Heinrich-Plett-Str. 40, 34132 Kassel
We are building a measurement methodology for selective spectroscopy of long-lived states with a calcium ion. We want to use binary search on the 42S1/2-32D5/2 transition of the calcium atom for the resonance search. Through the use of composite pulses techniques, we will change the narrow excitation profile with a passband pulse [1] for binary search. The final goal is to employ this method to identify the long-lived states of the lanthanoid molecular ions [2] targeting their use in molecular quantum information processing platforms.
