Atom-light hybrid interferometer for atomic sensing with quantum memory
Xingchang Wang, Xinyun Liang, Liang Dong +7
Quantum memories feature a reversible conversion of optical fields into long-lived atomic spin waves, and are therefore ideal for operating as sensitive atomic sensors. However, up…

Heisenberg scaling in optical magnetometry with measurement-induced correlations as a quantum resource
Georg Engelhardt, Ming Li, Xingchang Wang +2
Theoretical proposals to reach the Heisenberg scaling of the measurement precision typically require carefully engineered interactions or initial entanglement. In studying optical…

Light-induced fictitious magnetic fields for quantum storage in cold atomic ensembles
Jianmin Wang, Liang Dong, Xingchang Wang +4
In this work, we have demonstrated that optically generated fictitious magnetic fields can be utilized to extend the lifetime of quantum memories in cold atomic ensembles. All the…
