Quantum Simulation with Ytterbium Rydberg Atoms in Optical Tweezer Arrays

Oral

Abstract

Neutral atoms in optical tweezer arrays are rapidly emerging as a powerful platform for quantum computing, quantum simulation, and precision metrology, enabled by high‑fidelity control and tunable long‑range interactions. In our quantum computing and simulation experiment, individual 171Yb-atoms are confined in a 759 nm optical tweezer array that provides triple-magic trapping for the 1S0 ground state, the 3P1 state relevant for cooling and detection, as well as the 3P0 clock state. Here, we characterise single‑atom loading, demonstrating near-deterministic loading efficiencies exceeding 80%, using pulses red‑detuned from the 1S03P1 transition. By varying tweezer depth and magnetic field, we identify optimal operating conditions near the AC‑Stark‑ and Zeeman‑shifted resonance of the 𝐹 = 3/2, 𝑚𝐹 = - 1/2 hyperfine state. We further present our recent results on qubit manipulation within the OMG-architecture.
