Comment on "Resurgence of Rayleigh's curse in the presence of partial coherence"

Abstract

Larson and Saleh [Optica 5, 1382 (2018)] suggest that Rayeleigh's curse can recur and become unavoidable if the two sources are partially coherent. Here we show that their calculations and assertions have fundamental problems, and spatial-mode demultiplexing (SPADE) can overcome Rayleigh's curse even for partially coherent sources.
