Quantum interference in the presence of a resonant medium

DA Kalashnikov, EV Melik-Gaykazyan, AA Kalachev… - Scientific reports, 2017 - nature.com
Interaction of light with media often occurs with a femtosecond response time. Its
measurement by conventional techniques requires the use of femtosecond lasers and …

Teleportation-Based Error Correction Protocol of Time–Frequency Qubit States

N Fabre - Applied Sciences, 2023 - mdpi.com
We present a linear optical protocol for teleporting and correcting both temporal and

Propagation of temporal mode multiplexed optical fields in fibers: influence of dispersion

W Zhao, N Huo, L Cui, X Li, ZY Ou - Optics Express, 2021 - opg.optica.org
Exploiting two interfering fields which are initially in the same temporal mode but with the
spectra altered by propagating through different fibers, we characterize how the spectral …
