Centralizing Task-based Approach to Quantum Network Control
Alexander Pirker, Robert J. Hayek, Alexander Kolar +3
For the last decade, layered stacks have dominated the way of reasoning about architectures for quantum networks. However, layered architectures impose stringent design and timing…
Addressing a device in a quantum network: A quantum approach including routing
Alexander Pirker
In this work we propose an addressing scheme for quantum networks which relies on quantum states held by devices. Quantum network devices use their address state together with a re…
Flexible Qubit Allocation of Network Resource States
Francesco Mazza, Jorge Miguel-Ramiro, Jessica Illiano +4
The Quantum Internet is still in its infancy, yet identifying scalable and resilient quantum network resource states is an essential task for realizing it. We explore the use of gr…
QPing: a Quantum Ping Primitive for Quantum Networks
Jorge Miguel-Ramiro, Jessica Illiano, Francesco Mazza +5
We introduce the concept of Quantum Ping (QPing) as a diagnostic primitive for future quantum networks, designed to assess whether two or more end nodes can establish practical qua…
A resource-centric, task-based approach to quantum network control
Alexander Pirker, Belen Munoz, Wolfgang Dür
Quantum networks exhibit fundamental differences from their classical counterparts. These differences necessitate novel principles when organizing, managing, and operating them. He…
Graph state extraction from two-dimensional cluster states
Julia Freund, Alexander Pirker, Lina Vandré +1
We propose schemes to extract arbitrary graph states from two-dimensional cluster states by locally manipulating the qubits solely via single-qubit measurements. We introduce graph…
Improving entanglement purification through coherent superposition of roles
Jorge Miguel-Ramiro, Alexander Pirker, Wolfgang Dür
Entanglement purification and distillation protocols are essential for harnessing the full potential of quantum communication technologies. Multiple strategies have been proposed t…
Flexible quantum data bus for quantum networks
Julia Freund, Alexander Pirker, Wolfgang Dür
We consider multi-path routing of entanglement in quantum networks, where a pre-prepared multipartite entangled 2D cluster state serves as a resource to perform different tasks on…
Optimized Quantum Networks
Jorge Miguel-Ramiro, Alexander Pirker, Wolfgang Dür
The topology of classical networks is determined by physical links between nodes, and after a network request the links are used to establish the desired connections. Quantum netwo…
Coherent randomized benchmarking
Jorge Miguel-Ramiro, Alexander Pirker, Wolfgang Dür
Randomized benchmarking is a powerful technique to efficiently estimate the performance and reliability of quantum gates, circuits and devices. Here we propose to perform randomize…
Genuine quantum networks: superposed tasks and addressing
Jorge Miguel-Ramiro, Alexander Pirker, Wolfgang Dür
We show how to make quantum networks, both standard and entanglement-based, genuine quantum by providing them with the possibility of handling superposed tasks and superposed addre…

A. Pirker, W. Dür
We present a stack model for breaking down the complexity of entanglement-based quantum networks. More specifically, we focus on the structures and architectures of quantum network…
Multipartite entanglement outperforming bipartite entanglement under limited quantum system sizes
Hayata Yamasaki, Alexander Pirker, Mio Murao +2
Multipartite quantum entanglement serves as a resource for spatially separated parties performing distributed quantum information processing. Any multipartite entangled state can b…

We introduce a repeater scheme to efficiently distribute multipartite entangled states in a quantum network with optimal scaling. The scheme allows to generate graph states such as…
Simple proof of confidentiality for private quantum channels in noisy environments
A. Pirker, M. Zwerger, V. Dunjko +2
Complete security proofs for quantum communication protocols can be notoriously involved, which convolutes their verification, and obfuscates the key physical insights the security…
