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-…
Overcoming frequency resolution limits using a solid-state spin quantum sensor
Qingyun Cao, Genko T. Genov, Yaoming Chu +4
The ability to determine precisely the separation of two frequencies is fundamental to spectroscopy, yet the resolution limit poses a critical challenge: distinguishing two incoher…
Protecting Quantum Information via Destructive Interference of Correlated Noise
Alon Salhov, Qingyun Cao, Jianming Cai +3
Decoherence and imperfect control are crucial challenges for quantum technologies. Common protection strategies rely on noise temporal autocorrelation, which is not optimal if othe…
Protecting quantum spin coherence of nanodiamonds in living cells
Q. -Y. Cao, P. -C. Yang, M. -S. Gong +9
Due to its superior coherent and optical properties at room temperature, the nitrogen-vacancy (N-V ) center in diamond has become a promising quantum probe for nanoscale quantum se…
Ultrasensitive Magnetometer Using a Single Atom
I. Baumgart, J. -M. Cai, A. Retzker +2
Precision sensing, and in particular high precision magnetometry, is a central goal of research into quantum technologies. For magnetometers, often trade-offs exist between sensiti…
Detecting and polarizing nuclear spins with double resonance on a single electron spin
P. London, J. Scheuer, J. -M. Cai +11
We report the detection and polarization of nuclear spins in diamond at room temperature by using a single nitrogen-vacancy (NV) center. We use Hartmann-Hahn double resonance to co…
