Quantum network is the key to enable distributed quantum information processing. As the single-link communication rate decays exponentially with the distance, to enable reliable end-to-end quantum communication, the number of nodes need to grow with the network scale. For highly connected networks, we identify a threshold transition in the capacity as the density of network nodes increases---below a critical density, the rate is almost zero, while above the threshold the rate increases linearly… Expand

Statistical Properties of the Quantum Internet.
TLDR
A model to simulate a quantum internet based on optical fibers is proposed and network-theory techniques are employed to characterize the statistical properties of the photonic networks it generates, predicting a continuous phase transition between a disconnected and a highly connected phase.

End-to-end capacities of a quantum communication network
TLDR
This work derives single-letter upper bounds for the end-to-end capacities achievable by the most general (adaptive) protocols of quantum and private communication, from a single repeater chain to an arbitrarily complex quantum network, where systems may be routed through single or multiple paths.

Optimizing repeater schemes for the quantum internet
TLDR
An algorithm is developed that can efficiently perform a heuristic optimisation over a subset of quantum repeater schemes for general repeater platforms and makes estimates on what are the most critical parameters to improve for entanglement generation, how many repeaters to use, and which implementations perform best in their ability to generateEntanglement.

Designing Quantum Networks Using Preexisting Infrastructure
TLDR
This work proposes a method based on integer linear programming (ILP) to place the minimal number of repeaters on such an existing network topology, such that requirements on end-to-end entanglement-generation rate and fidelity between any pair of end-nodes are satisfied. Expand
Entanglement formation in continuous-variable random quantum networks
TLDR
By mapping the ensemble-averaged entanglement dynamics on an arbitrary network to a random-walk process on a graph, this work is able to exactly solve the entangler dynamics. Expand
Entanglement generation in a quantum network at distance-independent rate
TLDR
A protocol for entanglement generation in the quantum internet that allows a repeater node to use Greenberger-Horne-Zeilinger (GHZ) projective measurements that can fuse successfully-entangled Bell pairs shared across network edges, incident at that node is developed. Expand
Genuine quantum networks with superposed tasks and addressing
TLDR
This work shows how to make quantum networks, both standard and entanglement-based, genuine quantum by providing them with the possibility of handling superposed tasks and superposed addressing, and shows that externally controlling quantum superposition of tasks offers new possibilities and advantages over usually considered single functionality.
