Characterising Interleaver Length in a Turbulent Deployed Terrestrial Free-Space Optical Link
Kadir Gümüş, Vincent van Vliet, Menno van den Hout +3
We investigate the correlation between interleaver length and turbulence for a deployed terrestrial free-space optical link spanning 4.6 km. Using 24 hours of measurements, we show…
Reducing Turbulence-Induced Outages in a Deployed Terrestrial Free-Space Optical Communication Link via Interleaving
Kadir Gümüş, Vincent van Vliet, Menno van den Hout +3
We present an experimental study of data interleaving for terrestrial free-space optical communication over a 4.6~km urban testbed. Results demonstrate a two-order-of-magnitude red…
Multi-Modal Fiber Sensing for OffshoreEnvironmental and Infrastructure Monitoring
Konstantinos Alexoudis, Florian Azendorf, Alvaro Doval +5
Monitoring a 118 km subsea cable using Distributed acoustic, state-of-polarization, and Brillouin sensing captured storm-induced strain up to (dynamic) and $\app…
Dispersive Hong-Ou-Mandel Interference with Finite Coincidence Windows
T. J. Walstra, A. J. Hasenack, D. J. de Ruiter +3
Hong-Ou-Mandel (HOM) interference is a fundamental tool for assessing photon indistinguishability in quantum information processing. While the effect of chromatic dispersion on HOM…
Precise Localization of High-Voltage Breakdown Events using -Optical Time-Domain Reflectometry on an Optical Ground Wire
Konstantinos Alexoudis, Luke Silvestre, Tom Huiskamp +6
We present -OTDR for detecting and localising full spark-gap breakdowns by analysing backscattered light phase and frequency-domain signatures during high-voltage discharges syn…
Real-Time Diverse Fiber Sensing Multi-Event Detection using Phase OTDR Measurements
Konstantinos Alexoudis, Jasper Müller, Sai Kireet Patri +6
We demonstrate an experimental phase optical time-domain reflectometry (OTDR) system capable of simultaneous detection and classification of various environmental events, such as w…
Early Termination of Low-Density Parity-Check Codes for Continuous-Variable Quantum Key Distribution
Kadir Gümüş, João dos Reis Frazão, Vincent van Vliet +4
We analyse the impact of log a-posteriori early termination on the decoding throughput of reconciliation for continuous-variable quantum key distribution. Increases in decoded secr…
Short Blocklength Error Correction Codes for Continuous-Variable Quantum Key Distribution
Kadir Gümüş, João dos Reis Frazão, Boris Škorić +4
We introduce a two-step error correction scheme for reconciliation in continuous-variable quantum key distribution systems. Using this scheme, it is possible to use error correctio…
Mitigation of Polarization-Induced Fading in Optical Vector Network Analyzer for the Characterization of km-scale Space-Division Multiplexing Fibers
Besma Kalla, Martina Cappelletti, Menno van den Hout +5
We propose an optimized optical vector network analyzer with automatic polarization control to stabilize the reference arm polarization throughout the sweep range. We demonstrate t…
Information Reconciliation for Continuous-Variable Quantum Key Distribution with Using Short Blocklength Error Correction Codes: Proposal and Concerns
Kadir Gümüş, João dos Reis Frazão, Aaron Albores-Mejia +5
In this paper, we introduce a reconciliation protocol with a two-step error correction scheme that uses a short-blocklength, low-rate code and a long-blocklength, high-rate code. W…
Rate-adaptive Reconciliation for Experimental Continuous-variable Quantum Key Distribution with Discrete Modulation over a Free-space Optical Link
Kadir Gümüş, João dos Reis Frazão, Vincent van Vliet +8
Continuous-variable quantum key distribution (CV-QKD) has been proposed as a method for securely exchanging keys to protect against the security concerns caused by potential advanc…
Polarization Purity and Dispersion Characteristics of Nested Antiresonant Nodeless Hollow-Core Optical Fiber at Near- and Short-wave-IR Wavelengths for Quantum Communications
Ivi Afxenti, Lijun Yu, Taylor Shields +5
Advancements in quantum communication and sensing require improved optical transmission that ensures excellent state purity and reduced losses. While free-space optical communicati…
