Efficient formation and identification of single emitters in 4H-SiC following maskless heavy ion implantation
S. Eserin, L. K. S. Zimmermann, E. Schneider +12
Single photon emitters in silicon carbide (SiC) are a leading platform for scalable quantum technologies. Recent interest has focused on oxygen-vacancy-related emitters, which show…
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…
Demonstration of quantum network protocols over a 14-km urban fiber link
Stephan Kucera, Christian Haen, Elena Arenskötter +9
We report on the implementation of quantum entanglement distribution and quantum state teleportation over a 14.4-km urban dark-fiber link, which is partially underground, partially…
Quantum repeater node with free-space coupled trapped ions
Max Bergerhoff, Omar Elshehy, Stephan Kucera +2
The quantum repeater cell is a basic building block for a quantum network, as it allows to overcome the distance limitations due to unavoidable fiber loss in direct transmission. W…
