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 …

A quantum internet is the holy grail of quantum information processing, enabling the
deployment of a broad range of quantum technologies and protocols on a global scale …

All our former experience with application of quantum theory seems to say that what is
predicted by quantum formalism must occur in the laboratory. But the essence of quantum …

Quantum communications promises reliable transmission of quantum information, efficient
distribution of entanglement and generation of completely secure keys. For all these tasks …

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 information theory is a branch of science at the frontier of physics, mathematics,
and information science, and offers a variety of solutions that are impossible using classical …

How can one prove that a given quantum state is entangled? In this paper we review
different methods that have been proposed for entanglement detection. We first explain the …

We review the theory of entanglement measures, concentrating mostly on the finite
dimensional two-party case. Topics covered include: single-copy and asymptotic …

It is proven that logarithmic negativity does not increase on average under a general positive
partial transpose preserving operation (a set of operations that incorporate local operations …

In quantum mechanics, a fundamental law prevents quantum communications to
simultaneously achieve high rates and long distances. This limitation is well known for point …
