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…

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…

Indistinguishability of photonic qubits emitted from trapped Ca ions via pulsed excitation
Pascal Baumgart, Max Bergerhoff, Jonas Meiers +2
We investigate the indistinguishability of Raman photons generated from two trapped Ca ions using few-nanosecond excitation pulses. We elucidate how spontaneous scatteri…
