High-frequency dual-channel lock-in detection via rapidly oscillating driving
Kangze Li, Xu Zhao, Liantuan Xiao +1
Here we propose a general protocol for dual-channel lock-in detection of high-frequency ac signals. We find that the effect of a high-frequency target signal can be modulated throu…

Quantum Lock-In Detection via Successive Adiabatic Evolution
Kangze Li, Siqi Chen, Hao Zhang +3
The paper introduces a quantum lock‑in detection scheme based on successive adiabatic evolution that uses triangular‑wave modulation to eliminate spectral leakage and improve the d…

High-resolution wide-field magnetic imaging with sparse sampling using nitrogen-vacancy centers
Keqing Liu, Jiazhao Tian, Bokun Duan +7
Nitrogen-vacancy (NV) centers in diamond enable quantitative magnetic imaging, yet practical implementations must balance spatial resolution against acquisition time (and thus per-…
