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: In this paper, a single photon detector with a silicon avalanche photodiode and a quenching circuit is presented, which exhibits a dead time as low as 75 ns and a relatively low afterpulsing probability of 7.5% at 5 V excess bias voltage.

TL;DR: This work investigates the performance of separate absorption multiplication InGaAs/InP avalanche photodiodes as single-photon detectors for 1.3- and 1.55-mum wavelengths and compares them with a germanium avalanche photodiode, which shows a lower dark-count rate.
