On superresolution imaging as a multiparameter estimation problem
arXiv:1709.08392 · doi:10.1142/S0219749917400056
Abstract
We consider the problem of characterising the spatial extent of a composite light source using the superresolution imaging technique when the centroid of the source is not known precisely. We show that the essential features of this problem can be mapped onto a simple qubit model for joint estimation of a phase shift and a dephasing strength.
