Time-Spatial Mode Selective Quantum Frequency Converter
Santosh Kumar, He Zhang, Prajnesh Kumar +3
We experimentally demonstrate a mode-selective quantum frequency converter over a compound spatio-temporal Hilbert space. We show that our method can achieve high-extinction for hi…

A Super-resolution Optical Classifier with High Photon Efficiency
He Zhang, Santosh Kumar, Yu-Ping Huang
We propose and demonstrate a photon-efficient optical classifier to overcome the Rayleigh limit in spatial resolution. It utilizes mode-selective sum frequency generation and singl…
