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 …

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 …

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 …

A future quantum network will consist of quantum processors that are connected by quantum
channels, just like conventional computers are wired up to form the Internet. In contrast to …

Quantum channels enable the implementation of communication tasks inaccessible to their
classical counterparts. The most famous example is the distribution of secret key. However …

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

A global quantum repeater network involving satellite-based links is likely to have
advantages over fiber-based networks in terms of long-distance communication, since the …

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 …

Long-distance quantum communication will require the use of quantum repeaters to
overcome the exponential attenuation of signal with distance. One class of such repeaters …

We study a quantum entanglement switch that serves k users in a star topology. We model
variants of the system using continuous-time Markov chains (CTMCs) and obtain …
