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 ...

Nanophotonic quantum network node with neutral atoms and an integrated telecom interface
New Journal of Physics, 2020 The realization of a long-distance, distributed quantum network based on quantum memory nodes that are linked by photonic channels remains an outstanding challenge.

Secure Quantum Network Coding on Butterfly Network [PDF]
Quantum Sci. Technol. vol.3, 014001 (2017), 2017 Quantum network coding on the butterfly network has been studied as a typical example of quantum multiple cast network. We propose secure quantum network coding on the butterfly network in the multiple unicast setting based on a secure classical network coding. This protocol certainly transmits quantum states when there is no attack.

Exploring Multipartite Steering Effect Using Bell Operators
Entropy, 2019 While Bell operators are exploited in detecting Bell nonlocality and entanglement classification, we demonstrate their usefulness in exploring Einstein−Podolsky−Rosen (EPR) steering, which represents the quantum correlation intermediate ...

IEEE Photonics Journal, 2023 Measurement-device-independent quantum key distribution (MDI-QKD) can remove all detector side-channel attacks. However, there are still some assumptions on source preparations in MDI-QKD protocols, which are too strict to achieve in real-life ...

On the Characterization of Quantum Flip Stars with Quantum Network Tomography [PDF]
arXiv, 2023 The experimental realization of quantum information systems will be difficult due to how sensitive quantum information is to noise. Overcoming this sensitivity is central to designing quantum networks capable of transmitting quantum information reliably over large distances.

Satellite-Relayed Intercontinental Quantum Network. [PDF]
Physical Review Letters, 2018 We perform decoy-state quantum key distribution between a low-Earth-orbit satellite and multiple ground stations located in Xinglong, Nanshan, and Graz, which establish satellite-to-ground secure keys with ∼kHz rate per passage of the satellite Micius ...

Open-Destination Measurement-Device-Independent Quantum Key Distribution Network
Entropy, 2020 Quantum key distribution (QKD) networks hold promise for sharing secure randomness over multi-partities. Most existing QKD network schemes and demonstrations are based on trusted relays or limited to point-to-point scenario.

Experimental vulnerability analysis of QKD based on attack ratings
Scientific Reports, 2021 Inspired by the methodology used for classical cryptographic hardware, we consider the use of attack ratings in the context of QKD security evaluation. To illustrate the relevance of this approach, we conduct an experimental vulnerability assessment of ...
