Quantum computing with metastable ¹⁷¹Yb qubits

Neutral atom quantum computing is a rapidly developing field, but many challenges remain to implementing large-scale computing systems. I will discuss how a particular implementation based on ¹⁷¹Yb atoms, with qubits encoded in the metastable state, can give rise to important advantages to achieve hardware-efficient QEC by converting the dominant errors into erasure errors that can be detected with very low overhead. I will also discuss progress towards mid-circuit loss detection and atom replacement.
