Network Quantum Steering [PDF]
Physical Review Letters, 2021 The development of large-scale quantum networks promises to bring a multitude of technological applications as well as shed light on foundational topics, such as quantum nonlocality. It is particularly interesting to consider scenarios where sources within the network are statistically independent, which leads to so-called network nonlocality, even ...

Quantum network utility: A framework for benchmarking quantum networks. [PDF]
Proc Natl Acad Sci U S AThe central aim of quantum networks is to facilitate user connectivity via quantum channels, but there is an open need for benchmarking metrics to compare diverse quantum networks. Here, we propose a general framework for quantifying the performance of a quantum network by estimating the value created by connecting users through quantum channels.

Google in a Quantum Network [PDF]
Scientific Reports, 2012 We introduce the characterization of a class of quantum PageRank algorithms in a scenario in which some kind of quantum network is realizable out of the current classical internet web, but no quantum computer is yet available. This class represents a quantization of the PageRank protocol currently employed to list web pages according to their ...

Quantum diagrams and quantum networks [PDF]
SPIE Proceedings, 2014 This paper is an introduction to diagrammatic methods for representing quantum processes and quantum computing. We review basic notions for quantum information and quantum computing. We discuss topological diagrams and some issues about using category theory in representing quantum computing and teleportation. We analyze very carefully the diagrammatic

Quantum, 2023 The topology of classical networks is determined by physical links between nodes, and after a network request the links are used to establish the desired connections. Quantum networks offer the possibility to generate different kinds of entanglement prior to network requests, which can substitute links and allow one to fulfill multiple network requests

Aggregating Quantum Networks [PDF]
OSA Advanced Photonics Congress 2021, 2020 The implementation of quantum error-correction codes needs high efficiency transmission channels and significant physical resources. Here we show that aggregating quantum networks alleviate those issues when applied to the quantum Reed-Salomon code.

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.

Cambridge quantum network [PDF]
npj Quantum Information, 2019 AbstractFuture-proofing current fibre networks with quantum key distribution (QKD) is an attractive approach to combat the ever growing breaches of data theft. To succeed, this approach must offer broadband transport of quantum keys, efficient quantum key delivery and seamless user interaction, all within the existing fibre network.

Quantum Network Discrimination [PDF]
Quantum, 2023 Discrimination between objects, in particular quantum states, is one of the most fundamental tasks in (quantum) information theory. Recent years have seen significant progress towards extending the framework to point-to-point quantum channels. However, with technological progress the focus of the field is shifting to more complex structures: Quantum ...
