Fundamental limits of pulsed quantum light spectroscopy: Dipole moment estimation
Francesco Albarelli, Evangelia Bisketzi, Aiman Khan, Animesh Datta · Physical Review A · 2023
In order to rigorously find the limit of estimation precision for an atom probed by a quantum light pulse, the authors incorporate tools from quantum metrology and atomic spectroscopy. Their methodology uses a Hamiltonian model of the light-matter interaction to compute the information in the quantum state of the light after interaction with the atom.
