Sensitivity threshold defines the optimal spin subset for ensemble quantum sensing
Suwan I. Kang, Minhyeok Kim, Sanghyo Park +3
Inhomogeneous broadening and spatial gradients in control fields inevitably produce large variations in characteristic sensitivity across spin ensembles. We derive an analytic expr…

Autonomously Designed Pulses for Precise, Site-Selective Control of Atomic Qubits
Sanghyo Park, Seuk Lee, Keunyoung Lee +2
Quantum computers based on cold-atom arrays offer long-lived qubits with programmable connectivity, yet their progress toward fault-tolerant operation is limited by the relatively…
