Limitations of nearest-neighbour quantum networks
Frederik Hahn, Axel Dahlberg, Jens Eisert +1
Quantum communication research has in recent years shifted to include multi-partite networks for which questions of quantum network routing naturally emerge. To understand the pote…
Extracting GHZ states from linear cluster states
Jarn de Jong, Frederik Hahn, Nikolay Tcholtchev +2
Quantum information processing architectures typically only allow for nearest-neighbour entanglement creation. In many cases, this prevents the direct generation of GHZ states, whi…
Classical multiparty computation using quantum resources
Marco Clementi, Anna Pappa, Andreas Eckstein +3
In this work, we demonstrate a new way to perform classical multiparty computing amongst parties with limited computational resources. Our method harnesses quantum resources to inc…
Equivalence in delegated quantum computing
Fabian Wiesner, Jens Eisert, Anna Pappa
Delegated quantum computing (DQC) enables limited clients to perform operations that are outside their capabilities remotely on a quantum server. Protocols for DQC are usually set…
Information Theoretically Secure Hypothesis Test for Temporally Unstructured Quantum Computation
Daniel Mills, Anna Pappa, Theodoros Kapourniotis +1
We propose a new composable and information-theoretically secure protocol to verify that a server has the power to sample from a sub-universal quantum machine implementing only com…
BrAIcht, a theatrical agent that speaks like Bertolt Brecht's characters
Baz Roland, Kristina Malyseva, Anna Pappa +1
This project introduces BrAIcht, an AI conversational agent that creates dialogues in the distinctive style of the famous German playwright Bertolt Brecht. BrAIcht is fine-tuned us…
