Universal Sensitivity Bound for Thermal Quantum Dynamic Sensing
Rui Zhang, Yang Yang, Wenkui Ding +1
This work unifies the equilibrium and non-equilibrium frameworks of quantum metrology within the context of many-body systems. We investigate dynamic sensing schemes to derive an u…

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…
