Floquet analysis of coherence in periodically driven diamond NV ensemble systems
Cuong M. Nguyen, Uijin Ko, Seong-Joo Lee +3
High-density nitrogen-vacancy (NV) ensembles are promising platforms for solid-state quantum sensing, but their performance is limited by dipolar interactions and inhomogeneous dep…

Frequency limits of sequential readout for sensing AC magnetic fields using nitrogen-vacancy centers in diamond
Santosh Ghimire, Seong-Joo Lee, Sangwon Oh +1
The nitrogen-vacancy (NV) centers in diamond have ability to sense alternating-current (AC) magnetic fields with high spatial resolution. However, the frequency range of AC sensing…

Quantum diamond microscopy with optimized magnetic field sensitivity and sub-ms temporal resolution
Sangwon Oh, Seong-Joo Lee, Jeong Hyun Shim +2
Quantum diamond magnetometers using lock-in detection have successfully detected weak bio-magnetic fields from neurons, a live mammalian muscle, and a live mouse heart. This opens…
