Preparation, detection and cooling of single Strontium atoms in optical tweezers — •Aaron Götzelmann1, Christian Hölzl1, Moritz Wirth1, Sebastian Weber2, and Florian Meinert1 — 15. Physikalisches Institut, Stuttgart, Germany — 2Institut für Theoretische Physik 3, Stuttgart, Germany
In recent years, ensembles of atoms individually trapped in optical tweezer arrays have proven excellent systems for quantum computing and quantum simulation. Here, I report on our endeavour to prepare, cool, and detect single Strontium atoms in optical tweezers. We have chosen to work at a tweezer wavelength that is magic for the metastable 3P2 and 3P0 fine-structure states, motivated by exploiting this pair of states as a fast qubit for gate-based quantum computing [1].
Atom cooling and detection strategies reported so far for tweezer-trapped Strontium typically exploit the narrow 1S0 to 3P1 laser-cooling transition under magic trapping conditions. I will present our results to control single atoms under conditions, for which the 1S0 to 3P1 transition is non-magic, comprising single-atom preparation, high-fidelity imaging and evidence for near ground state cooling.
