Nonreciprocal Relaxation Acceleration
Xingyu Zhang, Yihan Ma, Yue Liu +5
The authors demonstrate that a transient nonreciprocal dissipative channel can dramatically speed up the relaxation of a two‑mode bosonic system toward a nonequilibrium steady stat…
Beyond Photon Shot Noise: Chemical Limits in Spectrophotometric Precision
Georg Engelhardt, Dahai He, JunYan Luo
In this work, we investigate precision limitations in spectrophotometry (i.e., spectroscopic concentration measurements) imposed by chemical processes of molecules. Using the recen…
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…
Full-counting statistics and quantum information of dispersive readout with a squeezed environment
Ming Li, JunYan Luo, Gloria Platero +1
Motivated by the importance of dispersive readout in quantum technology, we study a prototypical dispersive readout setup that is probed by a squeezed vacuum in a time-reversal-sym…
Dynamical multipartite entanglement in a generalized Tavis-Cummings model with XY spin interaction
Yuguo Su, Zhijie Sun, Yiying Yan +5
Multipartite entanglement is a long-term pursuit in the resource theory, offering a potential resource for quantum metrology. Here, we present the dynamical multipartite entangleme…
Photon-resolved Floquet theory II: Open quantum systems
G. Engelhardt, JunYan Luo, V. M. Bastidas +1
Photon-resolved Floquet theory keeps track of the photon exchange of a quantum system with a coherent driving field. It thus complements the standard full-counting statistics that…
