High-resolution Spectroscopy and Single-photon Rydberg Excitation of Reconfigurable Ytterbium Atom Tweezer Arrays Utilizing a Metastable State

We present an experimental system for Rydberg tweezer arrays with ytterbium (Yb) atoms featuring internal state manipulation between the ground 1S0 and metastable 3P2 states, and single-photon excitation from the 3P2 to Rydberg states. In the experiments, single Yb atoms are trapped in two-dimension...

Description
Summary:We present an experimental system for Rydberg tweezer arrays with ytterbium (Yb) atoms featuring internal state manipulation between the ground 1S0 and metastable 3P2 states, and single-photon excitation from the 3P2 to Rydberg states. In the experiments, single Yb atoms are trapped in two-dimensional arrays of optical tweezers and are detected by fluorescence imaging with the intercombination 1S0↔3P1 transition, and the defect-free single atom arrays are prepared by the rearrangement with the feedback. We successfully perform high-resolution 1S0↔3P2 state spectroscopy for the single atoms, demonstrating the utility of this ultranarrow transition. We further perform single-photon excitation from the 3P2 to Rydberg states for the single atoms, which is a key for efficient Rydberg excitation. We also perform a systematic measurement of a complex energy structure of a series of D states including newly observed 3D3 states. The developed system shows the feasibility of future experiments towards quantum simulations and computations using single Yb atoms.
