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…

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…
