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…
