Capacity and SKR tradeoff in coexisting classical and CV-QKD metropolitan-reach optical links
Cagla Ozkan, Lucas Alves Zischler, Kadir Gumus +3
We demonstrate power-regime-dependent guardband optimization for quantum-classical coexistence in metropolitan DWDM. Quantum channel at band-edge with 100-150 GHz guardbands achiev…
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…
Accurate and Effective Model for Coexistence of Classical and Quantum Signals In Optical Fibers
Lucas Alves Zischler, Çağla Özkan, Tristan Vosshenrich +10
The rising interest in quantum-level communication has resulted in proposals for coexistence schemes with classical signals within the same fiber optic channel, where the most rece…
On Irradiance Distributions for Weakly Turbulent FSO Links: Log-Normal vs. Gamma-Gamma
Carmen Álvarez Roa, Yunus Can Gültekin, Vincent van Vliet +3
Weak turbulence is commonly modeled using the log-normal distribution. Our experimental results show that this distribution fails to capture irradiance fluctuations in this regime.…
Experimental Investigation of Availability in a 4.6 km Terrestrial Urban Coherent Free-Space Optical Communications Link
Vincent van Vliet, Menno van den Hout, Kadir Gümüş +2
We measured the outage probability of a 4.6-km urban free-space optical communication link over six days. High-speed power measurements reveal slow and fast fading effects, with li…
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…
5.7 Tb/s Transmission Over a 4.6 km Field-Deployed Free-Space Optical Link in Urban Environment
Vincent van Vliet, Menno van den Hout, Kadir Gümüş +2
We transmitted 5.7 Tb/s over a 4.6 km free-space optical link in an urban environment, spanning the city of Eindhoven, the Netherlands, using a 1.1 THz wide wavelength-division mul…
A Critical Analysis of Deployed Use Cases for Quantum Key Distribution and Comparison with Post-Quantum Cryptography
Nick Aquina, Bruno Cimoli, Soumya Das +7
Quantum Key Distribution (QKD) is currently being discussed as a technology to safeguard communication in a future where quantum computers compromise traditional public-key cryptos…
