Sensitivity threshold defines the optimal spin subset for ensemble quantum sensing
Suwan I. Kang, Minhyeok Kim, Sanghyo Park +3
Finite drive power leaves unavoidable spatial gradients in control fields, preventing spin ensembles from reaching the standard-quantum-limit sensitivity. We derive an analytic exp…

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…
