We review recent results on the simulation of quantum channels, the reduction of adaptive
protocols (teleportation stretching), and the derivation of converse bounds for quantum and …

Quantum key distribution allows for the generation of a secret key between distant parties
connected by a quantum channel such as optical fibre or free space. Unfortunately, the rate …

The rate at which quantum communication tasks can be performed using direct transmission
is fundamentally hindered by the channel loss. Quantum repeaters allow one, in principle, to …

One of the most sought-after goals in experimental quantum communication is the
implementation of a quantum repeater. The performance of quantum repeaters can be …

Bell measurements, which allow entanglement between uncorrelated distant particles, play
a central role in quantum communication. Indeed sharing, measuring and creating …

We show how adaptive protocols of quantum and private communication through bosonic
Gaussian channels can be simplifed into much easier block versions that involve resource …

We consider the simulation of a quantum channel by two parties who share a resource state
and may apply local operations assisted by classical communication (LOCC). One specific …

Bell measurements, entailing the projection onto one of the Bell states, play a key role in
quantum information and communication, where the outcome of a variety of protocols …

Quantum key distribution aims to distribute a secret key among distant parties linked by an
optical fiber or free space. Unfortunately, the main problem which limits the long distance …

The information-theoretic point of view on physics-and quantum mechanics in particular-has
led to exciting insights on what distinguishes our world from a classical one. In particular, it …
