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…

Direct measurement of quantum Fisher information
Xingyu Zhang, Xiao-Ming Lu, Jing Liu +2
In the adiabatic perturbation theory, Berry curvature is related to the generalized force, and the quantum metric tensor is linked with energy fluctuation. While the former is test…

Quantum information with conserved quantities
Jing Liu, Jing Cheng, Li-Bin Fu +1
Conserved quantities are crucial in quantum physics. Here we discuss a general scenario of Hamiltonians. All the Hamiltonians within this scenario share a common conserved quantity…
