Quantum chaos in small quantum networks [PDF]

open access: yesJournal of Modern Optics, 2000
We study a 2-spin quantum Turing architecture, in which discrete local rotations _m of the Turing head spin alternate with quantum controlled NOT-operations. We show that a single chaotic parameter input _m leads to a chaotic dynamics in the entire Hilbert space.

Ultrastrong coupling in single plexcitonic nanocubes

open access: yesNanophotonics, 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.

A Lower Size, Weight Acquisition and Tracking System for Airborne Quantum Communication

open access: yesIEEE Photonics Journal, 2022
The features of unmanned aerial vehicles (UAVs), such as strong manoeuvrability, small size, and light weight, make them considered to participate in free space optical (FSO) quantum communication, becoming an important part of the Space-Air-Ground ...

Quantum random networks [PDF]

open access: yesNature Physics, 2010
Networks have been widely explored in the context of classical statistical mechanics. But when quantum effects are added, qualitatively different behaviours emerge, even for the simplest cases.

Maximal qubit violation of n-locality inequalities in a star-shaped quantum network

open access: yesNew 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.

Quantum Switchboard with Coupled-Cavity Array

open access: yesEntropy, 2022
The ability to control the flow of quantum information is deterministically useful for scaling up quantum computation. In this paper, we demonstrate a controllable quantum switchboard which directs the teleportation protocol to one of two targets, fully ...

Quantum networks in the UK

open access: yesMetro 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 ...
