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…
