Protocols for creating and distilling multipartite GHZ states with Bell pairs
Sébastian de Bone, Runsheng Ouyang, Kenneth Goodenough +1
The distribution of high-quality Greenberger-Horne-Zeilinger (GHZ) states is at the heart of many quantum communication tasks, ranging from extending the baseline of telescopes to…
NetSquid, a NETwork Simulator for QUantum Information using Discrete events
Tim Coopmans, Robert Knegjens, Axel Dahlberg +13
In order to bring quantum networks into the real world, we would like to determine the requirements of quantum network protocols including the underlying quantum hardware. Because…
Optimising repeater schemes for the quantum internet
Kenneth Goodenough, David Elkouss, Stephanie Wehner
The rate at which quantum communication tasks can be performed using direct transmission is fundamentally hindered by the channel loss. Quantum repeaters allow, in principle, to ov…
Entanglement Distribution in a Quantum Network, a Multi-Commodity Flow-Based Approach
Kaushik Chakraborty, David Elkouss, Bruno Rijsman +1
We consider the problem of optimising the achievable EPR-pair distribution rate between multiple source-destination pairs in a quantum internet, where the repeaters may perform a p…
Efficient optimization of cut-offs in quantum repeater chains
Boxi Li, Tim Coopmans, David Elkouss
Quantum communication enables the implementation of tasks that are unachievable with classical resources. However, losses on the communication channel preclude the direct long-dist…
Key rates for quantum key distribution protocols with asymmetric noise
Gláucia Murta, Filip Rozpędek, Jérémy Ribeiro +2
We consider the asymptotic key rates achieved in the simplest quantum key distribution protocols, namely the BB84 and the six-state protocols, when non-uniform noise is present in…
