Fundamental limits of pulsed quantum light spectroscopy: Dipole moment estimation

F Albarelli, E Bisketzi, A Khan, A Datta - Physical Review A, 2023 - APS
We study the fundamental limits of the precision of estimating parameters of a quantum
matter system when it is probed by a traveling pulse of quantum light. In particular, we focus …

Does entanglement enhance single-molecule pulsed biphoton spectroscopy?

A Khan, F Albarelli, A Datta - Quantum Science and Technology, 2024 - iopscience.iop.org
It depends. For a single molecule interacting with one mode of a biphoton probe, we show
that the spectroscopic information has three contributions, only one of which is a genuine …
