Indistinguishability of photonic qubits emitted from trapped ${}^{40}$Ca${}^{+}$ ions via pulsed excitation

Pascal Baumgart, Max Bergerhoff, Jonas Meiers +2

We investigate the indistinguishability of Raman photons generated from two trapped ${}^{40}$Ca${}^{+}$ ions using few-nanosecond excitation pulses. We elucidate how spontaneous scatteri…
