Quantum cryptography is arguably the fastest growing area in quantum information science.
Novel theoretical protocols are designed on a regular basis, security proofs are constantly …

In principle, quantum key distribution (QKD) offers information-theoretic security based on
the laws of physics. In practice, however, the imperfections of realistic devices might …

Quantum key distribution (QKD), allows two distant parties to share encryption keys with
security based on physical laws. Experimentally, QKD has been implemented via optical …

Device-independent quantum key distribution (DI-QKD) provides the gold standard for
secure key exchange. Not only does it allow for information-theoretic security based on …

We propose a fully passive linear optical quantum key distribution (QKD) source that
implements both random decoy-state and encoding choices with postselection only, thus …

Although the unconditional security of quantum key distribution (QKD) has been widely
studied, the imperfections of the practical devices leave potential loopholes for Eve to spy …

Quantum key distribution (QKD), guaranteed by the principles of quantum mechanics, is one
of the most promising solutions for the future of secure communication. Integrated quantum …

The passive approach to quantum key distribution (QKD) consists of removing all active
modulation from the users' devices, a highly desirable countermeasure to get rid of …

Quantum key distribution (QKD) based on the laws of quantum physics allows the secure
distribution of secret keys over an insecure channel. Unfortunately, imperfect …

The establishment of quantum communication links over a global scale is enabled by
satellite nodes. We examine the influence of the Earth's atmosphere on the performance of …
