Entanglement generation in a quantum network at distance-independent rate [PDF]
npj Quantum Information, 2020 We develop a protocol for entanglement generation in the quantum internet that allows a repeater node to use n-qubit Greenberger-Horne-Zeilinger (GHZ) projective measurements that can fuse n successfully entangled links, i.e., two-qubit entangled Bell ...

Ultrastrong coupling in single plexcitonic nanocubes
Nanophotonics, 2020 Light-matter strong coupling is defined when the coupling strength exceeds the losses in the system, whereas ultrastrong coupling is not simply strong coupling with even larger coupling strength.

Asymmetric Quantum Multicast Network Coding: Asymmetric Optimal Cloning over Quantum Networks
Applied Sciences, 2022 Multicasting of quantum states is an essential feature of quantum internet. Since the noncloning theorem prohibits perfect cloning of an unknown quantum state, an appropriate protocol may depend on the purpose of the multicast.

A benchmarking procedure for quantum networks [PDF]
arXiv, 2021 We propose network benchmarking: a procedure to efficiently benchmark the quality of a quantum network link connecting quantum processors in a quantum network. This procedure is based on the standard randomized benchmarking protocol and provides an estimate for the fidelity of a quantum network link.

Metro and Data Center Optical Networks and Short-Reach Links IV, 2021 We describe recent progress in quantum secured optical networks in the UK. The Cambridge Quantum Network has been operating for several years with 3 nodes separated by between 5-10 km of installed fibre. All links are secured by QKD systems operating with secure key rates in excess of 1 Mb/s, the highest recorded long term key rates in a deployed ...

Robustness of Noisy Quantum Networks [PDF]
, 2021 Quantum networks are a new paradigm of complex networks, allowing us to harness networked quantum technologies and to develop a quantum internet. But how robust is a quantum network when its links and nodes start failing? We show that quantum networks based on typical noisy quantum-repeater nodes are prone to discontinuous phase transitions with ...

A quantum network of clocks [PDF]
Nature Physics, 2014 The development of precise atomic clocks has led to many scientific and technological advances that play an increasingly important role in modern society. Shared timing information constitutes a key resource for positioning and navigation with a direct correspondence between timing accuracy and precision in applications such as the Global Positioning ...

Maximal qubit violation of n-locality inequalities in a star-shaped quantum network
New Journal of Physics, 2017 Bell's theorem was a cornerstone for our understanding of quantum theory and the establishment of Bell non-locality played a crucial role in the development of quantum information.
