We present a single-photon to single-atom interface, where a heralded single photon generated by Spontaneous Parametric Conversion is absorbed by a single trapped ion, subsequently generating a single Raman-scattered photon that heralds the absorption event.
A quantum network combines the benefits of quantum systems regarding secure information transmission and calculational speed-up by employing quantum coherence and entanglement to store, transmit and process information. A promising platform for implementing such a network are atom-based quantum memories and processors, interconnected by photonic quantum… (More)
We demonstrate heralded absorption of a single laser photon by a single trapped atomic ion, thereby mapping the photonic polarization state onto the atomic spin state with 97.9(1)% average fidelity.
