Phase encoded quantum key distribution up to 380 km in standard telecom grade fiber enabled by baseline error optimization

open access: yesScientific Reports, 2023
Phase encoding in quantum key distribution (QKD) enables long-distance information-theoretic secure communication in optical fibers. We present a novel theoretical model characterizing errors from various sources in practical phase encoding-based QKD ...

A quantitative comparison of amplitude versus intensity interferometry for astronomy

open access: yesNew Journal of Physics, 2022
Astronomical imaging can be broadly classified into two types. The first type is amplitude interferometry, which includes conventional optical telescopes and very large baseline interferometry (VLBI).

Controlling polarization entanglement in biphotons generated with partially spatially coherent pump beam

open access: yesResults in Physics, 2021
We theoretically study the polarization entanglement and the non-local correlations manifested by biphotons using measures as concurrence and CHSH Bell test, generated in the spontaneous parametric down-conversion (SPDC) process for partially spatially ...

SURE-Fuse WFF: A Multi-Resolution Windowed Fourier Analysis for Interferometric Phase Denoising

open access: yesIEEE Access, 2019
Interferometric phase (InPhase) images, acquired by phase imaging systems, often suffer from two major degradations: 1) phase wrapping, caused by the sinusoidal 2π-periodic sensing mechanism, and 2) noise, introduced by the acquisition process or ...
