Telecom-compatible polarization-to-time-bin conversion of atom-photon entanglement for heterogeneous quantum networks
Christian Haen, Julian GroÃ-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…
Quantum Teleportation with Telecom Photons from Remote Quantum Emitters
Tim Strobel, Michal Vyvlecka, Ilenia Neureuther +13
The quest for a global quantum internet is based on the realization of a scalable network which requires quantum hardware with exceptional performance. Among them are quantum light…
