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…
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…
The QTF-Backbone: Proposal for a Nationwide Optical Fibre Backbone in Germany for Quantum Technology and Time and Frequency Metrology
Klaus Blaum, Peter Kaufmann, Jochen Kronjäger +168
The recent breakthroughs in the distribution of quantum information and high-precision time and frequency (T&F) signals over long-haul optical fibre networks have transformative po…
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…
