Quantum key distribution (QKD) offers a way for establishing information-theoretical secure
communications. An important part of QKD technology is a high-quality random number …

Quantum key distribution (QKD) is a secure key generation method between two distant
parties by wisely exploiting properties of quantum mechanics. In QKD, experimental …

The security of quantum key distribution (QKD) has been proven for different protocols, in
particular for the BB84 protocol. It has been shown that this scheme is robust against …

Here we present two new schemes for quantum key distribution (QKD) which neither require
entanglement nor require an ideal single photon source. Thus, the proposed protocols can …

With the help of a simple quantum key distribution (QKD) scheme, we discuss the relation
between BB84-type protocols and two-step-type ones. It is shown that they have the same …

In the following we will describe a number of different attack strategies on Quantum Key
Distribution protocols. First, we will discuss QKD protocols based on ideal sources, mainly …

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 …

We discuss the potential of quantum key distribution (QKD) for long-distance communication
by proposing an analysis of the errors caused by dark counts. We give sufficient conditions …

The Bennett-Brassard 1984 (BB84) protocol is the most widely implemented quantum key
distribution (QKD) scheme. However, despite enormous theoretical and experimental efforts …

Quantum key distribution (QKD) could be the most significant application of quantum
information theory. In nearly four decades, although substantial QKD protocols are …
