Overview
A technical implementation guide for Quantum Key Distribution (QKD) networks. Covers hardware requirements, fiber infrastructure, trusted node architecture, and integration with classical encryption systems.
What's Inside
QKD Protocols
BB84 uses polarization-encoded photons for key exchange, while E91 leverages entanglement. We compare protocol performance, security proofs, and practical implementation considerations including decoy states and device-independent QKD.
Network Architecture
Deploying QKD beyond point-to-point requires trusted node relaying or quantum repeaters. We cover mesh topologies, key management layers, and the SDN integration needed for dynamic QKD network configuration.
