Fisher-information training of optical sensing front ends from natural fluctuations
Abhinav Sinha, Kai Wang
Fisher-information-based optimization of programmable optical front ends in situ generally requires a response model or parameter-labeled measurements. We show that natural paramet…

Can Randomly Structured Metasurfaces Be Used for Quantum Tomography of High-Dimensional Spatial Qudits?
Yuming Niu, Kai Wang
Reconstructing the density matrix of the quantum state of photons through a tomographically complete set of measurements, known as quantum state tomography, is an essential task in…
