Parameter-Decoupled Superresolution with Airy-Disk-Informed Learning: Application to NGC 4486B
James Qu, Isabella L. Lee, Gang Zhang +3
Estimating the separation of two unresolved or nearly unresolved sources from recorded intensity images is difficult when source brightness, mutual coherence, and phase are unknown…
Parameter-Decoupled Quantum Superresolution without Multiparameter Estimation
X. -F. Qian
Quantum superresolution promises to resolve closely spaced sources beyond the diffraction limit, but existing approaches generally rely on idealized source properties or require si…
Wave-particle duality ellipse and application in quantum imaging with undetected photons
Pawan Khatiwada, Xiao-Feng Qian
We present a systematic framework to quantify the interplay between coherence and wave-particle duality in generic two-path interference systems. Our analysis reveals a closed-form…
Breaking the Diffraction Barrier for Passive Sources: Parameter-Decoupled Superresolution Assisted by Physics-Informed Machine Learning
Abdelali Sajia, Bilal Benzimoun, Pawan Khatiwada +2
We present a parameter-decoupled superresolution framework for estimating sub-wavelength separations of passive two-point sources without requiring prior knowledge or control of th…
Superresolution picks entanglement over coherence
Abdelali Sajia, X. -F. Qian
Fundamental wave features of light play an important role in the realization of superresolution for two spatially separated point sources. It has been shown that (partial) coherenc…
