Squeezed- and coherent-state quantum key distribution over a deployed hybrid fibre-free-space channel
Adnan A. E. Hajomer, Huy Q. Nguyen, Ivan Derkach +14
Quantum networks will combine optical fibre with free-space links, yet continuous-variable quantum key distribution (CV-QKD) has been developed predominantly for one medium or the…
Secret Key Rate Analysis of Distribution Matching Algorithms for Discrete-Modulated CV-QKD
Micael Dias, Caroline Alves, Gabrielly Roman +1
Continuous variable quantum key distribution protocols (CV-QKD) with discrete modulation have been intensively investigated to bridge the gap between ideal Gaussian modulation and…
Efficient Information Reconciliation for High-Dimensional Quantum Key Distribution
Ronny Müller, Domenico Ribezzo, Mujtaba Zahidy +3
The Information Reconciliation phase in quantum key distribution has significant impact on the range and throughput of any QKD system. We explore this stage for high-dimensional QK…
Information Reconciliation for High-Dimensional Quantum Key Distribution using Nonbinary LDPC codes
Ronny Müller, Davide Bacco, Leif Katsou Oxenløwe +1
Information Reconciliation is an essential part of Quantum Key distribution protocols that closely resembles Slepian-Wolf coding. The application of nonbinary LDPC codes in the Inf…
Generalized Time-bin Quantum Random Number Generator with Uncharacterized Devices
Hamid Tebyanian, Mujtaba Zahidy, Ronny Müller +3
Random number generators (RNG) based on quantum mechanics are captivating due to their security and unpredictability compared to conventional generators, such as pseudo-random numb…
Quantum Key Distribution using Deterministic Single-Photon Sources over a Field-Installed Fibre Link
