Limitations of Error Model Approximations in Quantum Network Simulation
Julia Freund, Jorge Miguel-Ramiro, Julius Wallnöfer +1
Efficient classical simulation of large-scale quantum networks frequently relies on noise approximations, which consider a restricted set of operators to describe noisy channels an…
Strategy optimization for quantum conference key agreement in asymmetric star networks
Janka Memmen, Julia Kunzelmann, Nathan Walk +2
The distribution of entangled states is a core task for quantum networks facilitating quantum communication, and the use of multipartite entangled states comes with its own set of…
Analytical and Compressed Simulation of Noisy Stabilizer Circuits
Paul Aigner, Jasmin Matti, Maria Flors Mor-Ruiz +2
We develop analytical and algorithmic techniques that enable efficient simulation of a broad class of noisy stabilizer circuits. We derive closed-form expressions of expectation va…
Localized Entanglement Purification
Katerina Stloukalova, Jorge Miguel-Ramiro, Wolfgang Dür +1
Entanglement purification protocols are fundamental primitives in quantum communication, enabling the distillation of high-quality entanglement using only local operations and clas…
Merging-Based Quantum Repeater
Maria Flors Mor-Ruiz, Jorge Miguel-Ramiro, Julius Wallnöfer +2
We introduce an alternative approach for the design of quantum repeaters based on generating entangled states of growing size. The scheme utilizes quantum merging operations, also…
Topical White Paper: A Case for Quantum Memories in Space
Mustafa Gündoğan, Thomas Jennewein, Faezeh Kimiaee Asadi +20
It has recently been theoretically shown that Quantum Memories (QM) could enable truly global quantum networking when deployed in space thereby surpassing the limited range of land…
Multipartite state generation in quantum networks with optimal scaling
Julius Wallnöfer, Alexander Pirker, Michael Zwerger +1
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…
Construction of optimal resources for concatenated quantum protocols
Alexander Pirker, Julius Wallnöfer, Hans J. Briegel +1
We consider the explicit construction of resource states for measurement-based quantum information processing. We concentrate on special-purpose resource states that are capable to…
Measurement based quantum communication with resource states generated by entanglement purification
Julius Wallnöfer, Wolfgang Dür
We investigate measurement-based quantum communication with noisy resource states that are generated by entanglement purification. We consider the transmission of encoded informati…
