Quantum dynamic response-based NV-diamond magnetometry: Robustness to decoherence and applications in motion detection of magnetic nanoparticles
Wenkui Ding, Xingyu Zhang, Jing Liu +1
We propose a novel quantum sensing protocol that leverages the dynamical response of physical observables to quenches in quantum systems. Specifically, we use the nitrogen-vacancy…

Fundamental Sensitivity Limits for non-Hermitian Quantum Sensors
Wenkui Ding, Xiaoguang Wang, Shu Chen
Considering non-Hermitian systems implemented by utilizing enlarged quantum systems, we determine the fundamental limits for the sensitivity of non-Hermitian sensors from the persp…

Relations between quantum metrology and criticality in general su(1, 1) systems
Rui Zhang, Wenkui Ding, Zhucheng Zhang +3
There is a prevalent effort to achieve quantum-enhanced metrology using criticality. However, the extent to which estimation precision is enhanced through criticality still needs f…
