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) 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 …

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 …

Quantum communication is rapidly gaining popularity due to its high security and
technological maturity. However, most implementations are limited to just two …

Reliable long-distance distribution of entanglement is a key technique for many quantum
applications, most notably quantum key distribution. Here, we present a continuously …

Quantum key distribution is proven to offer unconditional security in communication between
two remote users with ideal source and detection. Unfortunately, ideal devices never exist in …

We analyse the finite-size security of the efficient Bennett-Brassard 1984 protocol
implemented with decoy states and apply the results to a gigahertz-clocked quantum key …

Practical schemes for measurement-device-independent quantum key distribution using
phase and path or time encoding are presented. In addition to immunity to existing …

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 …

Abstract Internet of Things (IoT) ideates smart and inter-connected things capable of sharing
their perceptions through the Internet. These devices are different from conventional Internet …
