Data-driven structural diagnostics and autonomous alignment of complex optical systems
Peng Zhu, Chen Chen, Shuchang Ma +3
The quest for autonomous alignment and maintenance of complex free-space optical systems is increasingly urgent for large-scale neutral-atom quantum processors. Leveraging a high-f…
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…
Quantum Interference between Photons and Single Quanta of Stored Atomic Coherence
Xingchang Wang, Jianmin Wang, Zhiqiang Ren +4
Essential for building quantum networks over remote independent nodes, the indistinguishability of photons has been extensively studied by observing the coincidence dip in the Hong…
SU(2)-in-SU(1,1) Nested Interferometer for Highly Sensitive, Loss-Tolerant Quantum Metrology
Wei Du, Jia Kong, Jun Jia +6
We present experimental and theoretical results on a new interferometer topology that nests a SU(2) interferometer, e.g., a Mach-Zehnder or Michelson interferometer, inside a SU(1,…
