Telecom Compatibility Validation of Quantum Key Distribution Co-existing with 112 Gbps/λ/core Data Transmission in Non-Trench and Trench-Assistant Multicore Fibers
Rui Lin, Aleksejs Udalcovs, Oskars Ozolins +12
We experimentally characterize photon leakage from 112Gbps data channels in both non-trench and trench-assistant 7-core fibers, demonstrating telecom compatibility for QKD co-exist…
Few-Photon Heteorodyne Spectroscopy
Gustavo C Amaral, Thiago Ferreira da Silva, Guilherme P Temporão +1
We perform a high resolution Fourier Transform Spectroscopy of optical sources in the few-photon regime based on the phenomenon of two-photon interference in a beam splitter. From…
Linear-Optic Heralded Photon Source
Thiago Ferreira da Silva, Gustavo C. Amaral, Guilherme P. Temporão +1
We present a Heralded Photon Source based only on linear optics and weak coherent states. By time-tuning a Hong-Ou-Mandel interferometer fed with frequency-displaced coherent state…
Real-time monitoring of single-photon detectors against eavesdropping in quantum key distribution systems
T. Ferreira da Silva, G. B. Xavier, G. P. Temporão +1
By employing real-time monitoring of single-photon avalanche photodiodes we demonstrate how two types of practical eavesdropping strategies, the after-gate and time-shift attacks,…
Practical random number generation protocol for entanglement-based quantum key distribution
G. B. Xavier, T. Ferreira da Silva, G. Vilela de Faria +2
A simple protocol which takes advantage of the inherent random times of detections in single photon counting modules is presented for random active basis choices when using entangl…
