Quantum-Optimal Discrimination of Multiple Objects in Sub-Diffraction Incoherent Imaging
Michael R. Grace, Saikat Guha · Conference on Lasers and Electro-Optics · 2022
We derive the quantum limit for discriminating between M≥2 incoherent, diffraction-limited objects and identify a quantum-optimal measurement that can distinguish two orders of magnitude more objects than direct imaging with no additional error.
