TL;DR: Essential theoretical tools that have been developed to assess the security of the main experimental platforms are presented (discrete- variable, continuous-variable, and distributed-phase-reference protocols).

TL;DR: Two GHz-clocked QKD links enable the world-first secure TV conferencing over a distance of 45km to be demonstrated and detection of an eavesdropper, rerouting into a secure path, and key relay via trusted nodes are demonstrated in this network.

TL;DR: The paper presents the architecture and functionality of the principal networking agent?the SECOQC node module, which enables the authentic classical communication required for key distillation, manages the generated key material, determines a communication path between any destinations in the network, and realizes end-to-end secure transport of key material between these destinations.

TL;DR: In this paper, a novel secure communication network with quantum key distribution in a metropolitan area is reported, where different QKD schemes are integrated to demonstrate secure TV conferencing over a distance of 45km, stable long-term operation and application to secure mobile phones.

TL;DR: The theoretical foundations of continuous‐variable quantum key distribution (CV‐QKD) with Gaussian modulation are reviewed and the essential relations from scratch in a pedagogical way and a set of new original noise models are presented to get an estimate of how well a given set of hardware will perform in practice.
