Policies for elementary links in a quantum network [PDF]

open access: yesQuantum, 2020
Distributing entanglement over long distances is one of the central tasks in quantum networks. An important problem, especially for near-term quantum networks, is to develop optimal entanglement distribution protocols that take into account the ...

Quantum cryptographic network based on quantum memories [PDF]

open access: yesPhysical Review A, 1996
Quantum correlations between two particles show non-classical properties which can be used for providing secure transmission of information. We present a quantum cryptographic system, in which users store particles in quantum memories kept in a transmission center.

Completely quantum neural networks

open access: yesPhysical Review A, 2022
Artificial neural networks are at the heart of modern deep learning algorithms. We describe how to embed and train a general neural network in a quantum annealer without introducing any classical element in training. To implement the network on a state-of-the-art quantum annealer, we develop three crucial ingredients: binary encoding the free ...

Entanglement Distribution in a Quantum Network: A Multicommodity Flow-Based Approach [PDF]

open access: yesIEEE Transactions on Quantum Engineering, 2020
We consider the problem of optimizing the achievable EPR-pair distribution rate between multiple source-destination pairs in a quantum Internet, where the repeaters may perform a probabilistic Bell-state measurement and we may impose a minimum end-to-end

Multiphoton quantum communication in quantum networks [PDF]

open access: yesPhysical Review A, 2014
We propose and analyze a multiphoton-state coherent transport protocol in a coupled-resonator quantum network. A multiphoton swap gate between two antipodes can be achieved with neither external modulation nor coupling strength engineering. Moreover, we extend this result to a coupled-resonator chain of arbitrary length with different coupling ...

Semidefinite Tests for Quantum Network Topologies. [PDF]

open access: yesPhysical Review Letters, 2020
Quantum networks play a major role in long-distance communication, quantum cryptography, clock synchronization, and distributed quantum computing. Generally, these protocols involve many independent sources sharing entanglement among distant parties that,

Experimental quantum network coding [PDF]

open access: yesnpj Quantum Information, 2019
AbstractDistributing quantum state and entanglement between distant nodes is a crucial task in distributed quantum information processing on large-scale quantum networks. Quantum network coding provides an alternative solution for quantum-state distribution, especially when the bottleneck problems must be considered and high communication speed is ...

A Faraday laser lasing on Rb 1529 nm transition

open access: yesScientific 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.

Quantum network coding for quantum repeaters

open access: yes, 2012
This paper considers quantum network coding, which is a recent technique that enables quantum information to be sent on complex networks at higher rates than by using straightforward routing strategies. Kobayashi et al. have recently showed the potential
