Precise Photon Arrival Time Measurement via Time to Frequency Demultiplexing

Usman Khan, Santosh Kumar, Daniel Lopez +3

We demonstrate a nonlinear-optics approach to precise measurement of photon arrival time, by translating the temporal information of single photons to a wavelength distribution of…

First Photon Machine Learning

Lili Li, Santosh Kumar, Malvika Garikapati +1

Quantum techniques are expected to revolutionize how information is acquired, exchanged, and processed. Yet it has been a challenge to realize and measure their values in practical…

A Highly Efficient and Pure Few-Photon Source on Chip

Zhaohui Ma, Jia-Yang Chen, Malvika Garikapati +4

We report on multi-photon statistics of correlated twin beams produced in a periodic poled micro-ring resonator on thin-film lithium niobate. Owing to high cavity confinement and n…

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…
