Practical Methods for Distance-Adaptive Continuous-Variable Quantum Key Distribution
Jonas Berl, Utku Akin, Erdem Eray Cil +2
Continuous-variable quantum key distribution (CV-QKD) is a promising quantum-safe alternative to classical asymmetric cryptography that enables two authenticated parties to establi…
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…
A Transformer-Based Approach for Diagnosing Fault Cases in Optical Fiber Amplifiers
Dominic Schneider, Lutz Rapp, Christoph Ament
A transformer-based deep learning approach is presented that enables the diagnosis of fault cases in optical fiber amplifiers using condition-based monitoring time series data. The…
The QTF-Backbone: Proposal for a Nationwide Optical Fibre Backbone in Germany for Quantum Technology and Time and Frequency Metrology
Tara Cubel Liebisch, Peter Kaufmann, Harald Schnatz +166
The recent breakthroughs in the distribution of quantum information and high-precision time and frequency (T&F) signals over long-haul optical fibre networks have transformative po…
DemoQuanDT: A Carrier-Grade QKD Network
P. Horoschenkoff, J. Henrich, R. Böhn +20
Quantum Key Distribution Networks (QKDN) enable secure communication even in the age of powerful quantum computers. In the hands of a network operator, which can offer its service…
Co-propagation of QKD & 6 Tb/s (60x100G) DWDM channels with ~17 dBm total WDM power in single and multi-span configurations
P. Gavignet, E. Pincemin, F. Herviou +14
We report co-propagation experiments of the quantum channel (at 1310 nm) of a Quantum Key Distribution (QKD) system with Dense Wavelength Division Multiplexing (DWDM) data channels…
