Percolation Theories for Quantum Networks
Entropy, 2023 Quantum networks have experienced rapid advancements in both theoretical and experimental domains over the last decade, making it increasingly important to understand their large-scale features from the viewpoint of statistical physics. This review paper discusses a fundamental question: how can entanglement be effectively and indirectly (e.g., through

Quantum Algorithms for Josephson Networks [PDF]
Physical Review Letters, 2001 We analyze possible implementations of quantum algorithms in a system of (macroscopic) Josephson charge qubits. System layout and parameters to realize the Deutsch algorithm with up to three qubits are provided. Special attention is paid to the necessity of entangled states in the various implementations.

Qubit teleportation between non-neighbouring nodes in a quantum network [PDF]
Nature, 2021 Future quantum internet applications will derive their power from the ability to share quantum information across the network1,2. Quantum teleportation allows for the reliable transfer of quantum information between distant nodes, even in the presence of

Analysis of multipartite entanglement distribution using a central quantum-network node [PDF]
Physical Review A, 2022 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 where the multipartite entangled state is first prepared locally at ...

Robust Quantum Memory in a Trapped-Ion Quantum Network Node. [PDF]
Physical Review Letters, 2022 We integrate a long-lived memory qubit into a mixed-species trapped-ion quantum network node. Ion-photon entanglement first generated with a network qubit in ^{88}Sr^{+} is transferred to ^{43}Ca^{+} with 0.977(7) fidelity, and mapped to a robust memory ...

Colloquium : Cavity-enhanced quantum network nodes [PDF]
Reviews of Modern Physics, 2022 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 classical devices, however, the entanglement and non-local correlations

Conference key agreement in a quantum network [PDF]
npj Quantum Information, 2022 Quantum conference key agreement (QCKA) allows multiple users to establish a secure key from a shared multi-partite entangled state. In a quantum network, this protocol can be efficiently implemented using a single copy of a N-qubit Greenberger-Horne ...
