"Quantum computing with neutral Yb atoms"

Abstract: Quantum computing with neutral atoms has progressed rapidly in recent years, based on the development of optical tweezer arrays and quantum gates using the Rydberg blockade. The pioneering experiments have been done in alkali atoms, however, alkaline earth atoms offer several significant advantages that are poised to offer access to larger system sizes, higher gate fidelities, and improved quantum error correction [1–3]. In this talk, I will describe our experimental and theoretical efforts to develop a robust quantum computing platform based on nuclear spin qubits in 171Yb atom arrays. I will also describe a recent theoretical proposal to implement ultra-high-fidelity quantum gates using circular Rydberg states [4].
