Generalized Svetlichny Inequalities as a Cross-Platform Benchmark for Quantum Processors
Andrés Camilo Granda Arango, Giuseppe Sergioli, Luigi Iapichino +3
A cross-platform benchmark should be device-independent yet sensitive to imperfections accumulated during execution. Building on prior work, we formulate and validate a protocol th…
Nonlocality as a Benchmarking Tool for Quantum Processors
Andrés Camilo Granda Arango, Carla Sophie Rieger, Carlo Cuccu +5
Benchmarking quantum processors is a central task in every roadmap aimed at quantum advantage. Here, we discuss a benchmarking protocol based on the violation of the Svetlichny ine…
An asymmetric atom-photon architecture for device-independent quantum key distribution over 25 km
Jonas Meiers, Christian Haen, Max Bergerhoff +4
Device-independent quantum key distribution (DIQKD) can guarantee security without trusting the internal workings of the measurement devices, but extending it to fiber networks dem…
Telecom-compatible polarization-to-time-bin conversion of atom-photon entanglement for heterogeneous quantum networks
Christian Haen, Julian Groß-Funk, Max Bergerhoff +5
A key enabling feature of future quantum networks is interoperability between platforms that operate at different wavelengths and with different qubit encodings. We demonstrate an…
Highly indistinguishable photons from a tin-vacancy spin qubit in diamond
Dennis Herrmann, Robert Morsch-Golsong, Tobias Bauer +9
Quantum networks promise secure communication, distributed sensing and modular quantum computing by interconnecting distant quantum nodes through photonic links. Extending such net…
Time Evolution on Hybrid Tensor Networks -- A Novel and Parallelizable Algorithm
Tobias V. Bauer, Richard M. Milbradt, Christian B. Mendl
We develop a novel time-evolution algorithm for matrix product states based on the recently introduced hybrid tensor network (hTN) framework. We retain the tensors close to the bou…
Quantum repeater segment with free-space coupled co-trapped ions using telecom photon interference
Max Bergerhoff, Pascal Baumgart, Christian Haen +5
A quantum repeater segment is a basic building block of a quantum repeater, generating buffered entanglement of quantum memories to connect quantum repeater cells. It also enables…
