  • Author: Nils Scharnhorst
Techniques developed for quantum computing with trapped ions can be used to perform precision spectroscopy of ion species such as aluminum which has an ideal transition for an optical clock but cannot be laser cooled directly. In our project at Piet Schmidt’s Experimental Quantum Metrology group we set up an optical clock experiment with aluminum as the clock ion and a Ca+ the logic ion. The latter provides sympathetic cooling, state preparation, and internal state detection after interrogation of the clock transition.
