Quantum-limited estimation of atmospheric turbulence via spatial mode decomposition
A. Hrebeniuk, M. Klen, I. Karuseichyk +2
We establish the ultimate precision limit for estimating the optical spatial coherence radius (Fried parameter) within a quantum metrological framework. In the weak field regime, w…

Multiparameter estimation for the superresolution of two incoherent sources
Antonin Grateau, Alexander Boeschoten, Tanguy Favin-Lévêque +2
We experimentally demonstrate the simultaneous estimation of the three parameters characterizing a pair of incoherent optical sources in the sub-Rayleigh regime, enabling super-res…

Experimental Evidence-Based Sub-Rayleigh Source Discrimination
Saurabh U. Shringarpure, Yong Siah Teo, Hyunseok Jeong +5
We propose a Bayesian evidence-based inference framework based on relative belief ratios and apply it to discriminating between one and two incoherent optical point sources using s…
