    Apr 11, 2024We demonstrate coherent control of the fine-structure qubit in neutral strontium atoms. This qubit is encoded in the metastable $^{3}{P}_{2}$ and $^{3}{P}_{0}$ states, coupled by a Raman transition. Using a magnetic quadrupole transition, we demonstrate coherent state initialization of this THz qubit. We show Rabi oscillations with more than 60 coherent cycles and single-qubit rotations on the ...

    In our recent experiments, we demonstrate coherent control of a qubit encoded in the fine structure of neutral strontium atoms trapped in an optical lattice. We construct the qubit from metastable states coupled via a two-photon Raman transition and showcase high-fidelity qubit rotations with promising state initialization and readout methods.
