Neutral atom quantum computing is a rapidly developing field. Exploring new atomic species, such as alkaline earth atoms, provides additional opportunities for cooling and trapping, measurement, qubit manipulation, high-fidelity gates and quantum error correction. In this talk, I will present recent results from our group on implementing high-fidelity gates on nuclear spins encoded in metastable 171Yb atoms, including mid-circuit detection of gate errors that give rise to leakage out of the qubit space, using erasure conversion. I will conclude by discussing ongoing experiments on quantum error correction and reaching very high gate fidelities, and the important role of real-time FPGA control electronics developed by Fermilab in reaching these goals.
