We provide the ultimate precision attainable in spectroscopy of a quantum emitter using single-photon pulses. We find that the maximum precision of linewidth estimation is independent of the details of the emitter’s bare Hamiltonian, though this is not true for the detunings. We also identify optimal pulse shapes attaining these precisions.

Abstract
We provide the ultimate precision attainable in spectroscopy of a quantum emitter using single-photon pulses. We find that the maximum precision of linewidth estimation is independent of the details of the emitter’s bare Hamiltonian, though this is not true for the detunings. We also identify optimal pulse shapes attaining these precisions.File in questo prodotto:
