Quantum information and simulation with Ytterbium Tweezer Arrays

While much of the pioneering work with neutral atoms has focused on alkalis, our group along with several others have been exploring how alternative atomic species, like alkaline-earths, might enable advances in quantum computing. Ytterbium-171 is a particularly attractive candidate for quantum information processing, Ìýpossessing a robust nuclear-spin qubit that can be stored in both a ground and metastable configuration. The metastable state can be connected to Rydberg states with favorable properties for high-fidelity two-qubit gates. Meanwhile, a wealth of atomic transitions from the ground-state can enable high-fidelity, rapid atom images as well as mid-circuit operations, including measurement, cooling, and spin-reset. The combination of these features make this atom a promising candidate for quantum computing. A key focus of our work is understanding the challenges for using this atom for quantum error correction, while we also explore how ideas in quantum information processing can be exploited for other directions in quantum information science, e.g. hybrid analog-digital circuits and quantum error correction for metrology.Ìý
