It is generally accepted that quantum key distribution (QKD) could supply legitimate users
with unconditional security during their communication. Quite a lot of satisfactory efforts have …

The goal of any quantum key distribution (QKD) protocol is to generate a shared secret key
between two distant parties over a public communication channel. The crucial point here is …

The security of the previous quantum key distribution (QKD) protocols, which is guaranteed
by the nature of physics law, is based on the legitimate users. However, impersonation of the …

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 …

The best-known application of quantum cryptography is quantum key distribution (QKD). The
goal of QKD is to allow two distant participants, traditionally called Alice and Bob, to share a …

The security of two-state quantum-key distribution against individual attack is estimated
when the channel has losses and noises. We assume that Alice and Bob use two …

We present a complete protocol for BB84 quantum key distribution for a realistic setting
(noise, loss, multi-photon signals of the source) that covers many of todays experimental …

In 1984 Bennett and Brassard [1] proposed the first protocol which allows to distribute a
cryptographic key such that the security of this distribution is guaranteed by quantum …

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 security of a standard bidirectional “plug-and-play” quantum key distribution (QKD)
system has been an open question for a long time. This is mainly because its source is …
