Nature 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.

Quantum Science and Technology, 2022 Abstract Capsule networks (CapsNets), which incorporate the paradigms of connectionism and symbolism, have brought fresh insights into artificial intelligence (AI). The capsule, as the building block of CapsNets, is a group of neurons represented by a vector to encode different features of an entity.

Quantum copying: A network [PDF]
Physical Review A, 1997 We present a network consisting of quantum gates which produces two imperfect copies of an arbitrary qubit. The quality of the copies does not depend on the input qubit. We also show that for a restricted class of inputs it is possible to use a very similar network to produce three copies instead of two.

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.

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.

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 ...

A Faraday laser lasing on Rb 1529 nm transition
Scientific Reports, 2017 We present the design and performance characterization of a Faraday laser directly lasing on the Rb 1529 nm transition (Rb, 5P 3/2 − 4D 5/2) with high stability, narrow spectral linewidth and low cost.

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 ...

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 ...
