The second quantum revolution brings with it the promise of a quantum internet. As the first
quantum network hardware prototypes near completion new challenges emerge. A …

Quantum networks will enable the implementation of communication tasks with qualitative
advantages with respect to the communication networks known today. While it is expected …

We study the performance (rate and fidelity) of distributing multipartite entangled states in a
quantum network through the use of a central node. Specifically, we consider the scenario …

The standard approach to realize a quantum repeater relies upon probabilistic but heralded
entangled state manipulations and the storage of quantum states while waiting for …

We present an exact rate analysis for a secret key that can be shared among two parties
employing a linear quantum repeater chain. One of our main motivations is to address the …

Quantum communication enables a host of applications that cannot be achieved by classical
communication means, with provably secure communication as one of the prime examples …

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 …

Quantum communication enables the implementation of tasks that are unachievable with
classical resources. However, losses on the communication channel preclude the direct …
