Capacity-approaching Channel Codes for Discrete Variable Quantum Key Distribution (QKD) Applications
, 2013 Secure communications and cryptography is as old as civilization itself. The Greek Spartans for instance would cipher their military messages and, for Chinese, just the act of writing the message constituted a secret message since almost no-one could ...

Multimode fiber influence on time response of single-photon avalanche diodes used in QKD
, 2023 For quantum key distribution (QKD), single-photon avalanche diodes (SPAD) are limited by the full timing response. Here, we summarise the impact of multimode fiber SPAD timing response for an alternative coupling from single-mode fiber.

Numerical finite-key analysis of quantum key distribution
npj Quantum Information, 2020 Quantum key distribution (QKD) allows for secure communications safe against attacks by quantum computers. QKD protocols are performed by sending a sizeable, but finite, number of quantum signals between the distant parties involved. Many QKD experiments,

Two-Dimensional Quantum Key Distribution (QKD) Protocol for Increased Key Rate Fiber-Based Quantum Communications [PDF]
2017 European Conference on Optical Communication (ECOC), 2017 We experimentally prove a novel two-dimensional QKD scheme, relying on differential phasetime shifting (DPTS) of strongly attenuated weak coherent pulses. We demonstrate QKD transmission up to 170 km standard fiber, and even include a classical channel up to 90 km.

Engineering Reports, Volume 8, Issue 6, June 2026.This paper proposes a dynamic search cluster head selection method for resource occupancy protection switching. By integrating multidimensional fitness functions, energy consumption models, and closed‐loop control mechanisms, and combining optimized dynamic search strategies, the optimal cluster head is selected.

Preserving Quantum Coherence in Thermal Noisy Systems Via Qubit Frequency Modulation
Advanced Quantum Technologies, Volume 9, Issue 6, June 2026.Frequency modulation is shown to preserve quantum coherence in a thermal phase‐covariant environment only under specific noise conditions. It protects a qubit against thermal dissipation from a Lorentzian reservoir, but fails against thermal pure dephasing from an Ohmic reservoir.
