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 …

One of the best signatures of nonclassicality in a quantum system is the existence of
correlations that have no classical counterpart. Different methods for quantifying the …

We introduce a rigorous framework for the quantification of coherence and identify intuitive
and easily computable measures of coherence. We achieve this by adopting the viewpoint …

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 …

We present conditions every measure of entanglement has to satisfy, and construct a whole
class of “good” entanglement measures. The generalization of our class of entanglement …

We improve previously proposed conditions each measure of entanglement has to satisfy.
We present a class of entanglement measures that satisfy these conditions and show that …

We analyze the possibility of copying (that is, cloning) arbitrary states of a quantum-
mechanical spin-1/2 system. We show that there exists a ''universal quantum-copying …

We investigate the “teleportation” of a quantum state using three-particle entanglement to
either one of two receivers in such a way that, generally, either one of the two, but only one …

Monoidal category theory serves as a powerful framework for describing logical aspects of
quantum theory, giving an abstract language for parallel and sequential composition, and a …

Catalysts open up new reaction pathways that can speed up chemical reactions while not
consuming the catalyst. A similar phenomenon has been discovered in quantum information …
