Measurement-based feedback as a flexible tool to control non-Poissonian photon statistics
Ming Li, JunYan Luo, Georg Engelhardt
Non-Poissonian photon statistics are usually traced to nonlinear interactions, nonclassical states, or engineered reservoirs. Here we show that measurement-based feedback can be al…
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…
Photon-resolved Floquet theory approach to spectroscopic quantum sensing
Georg Engelhardt, Konstantin Dorfman, Zhedong Zhang
Spectroscopic methods play a vital role in quantum sensing, which uses the quantized nature of atoms or molecules to reach astonishing precision for sensing of, e.g., electric or m…
Anomalous current-electric field characteristics in transport through a nanoelectromechanical systems
Chengjie Wu, Yi Ding, Yiying Yan +6
A deep understanding of the correlation between electronic and mechanical degrees of freedom is crucial to the development of quantum devices in a nanoelectromechanical system (NEM…
Photon-resolved Floquet theory I: Full-Counting statistics of the driving field in Floquet systems
Georg Engelhardt, JunYan Luo, Victor M. Bastidas +1
Floquet theory and other established semiclassical approaches are widely used methods to predict the state of externally-driven quantum systems, yet, they do not allow to predict t…
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…
