Quantum key distribution (QKD) is the first quantum information task to reach the level of
mature technology, already fit for commercialization. It aims at the creation of a secret key …

The appealing feature of quantum key distribution (QKD), from a cryptographic viewpoint, is
the ability to prove the information-theoretic security (ITS) of the established keys. As a key …

A secure communication network with quantum key distribution in a metropolitan area is
reported. Six different QKD systems are integrated into a mesh-type network. GHz-clocked …

In this paper, we present the quantum key distribution (QKD) network designed and
implemented by the European project SEcure COmmunication based on Quantum …

Quantum-key-distribution (QKD) systems can send quantum signals over more than 100 km
standard optical fiber and are widely believed to be secure. Here, we show experimentally a …

These lecture notes grew out of a course on quantum key distribution taught at Leibniz
Universität Hannover during the summer term of 2020 as part of the physics master's …

Single photon detectors (SPDs) based on passively quenched avalanche photodiodes can
be temporarily blinded by relatively bright light, of intensity less than 1 nW. A bright-light …

Measurement-device-independent quantum key distribution with a finite number of decoy
states is analyzed under finite-data-size assumption. By accounting for statistical fluctuations …

Quantum key distribution (QKD) utilizes the laws of quantum mechanics to achieve
information-theoretically secure key generation. This field is now approaching the stage of …

It has previously been shown that the gated detectors of two commercially available
quantum key distribution (QKD) systems are blindable and controllable by an eavesdropper …
