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…

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…
