Programmable atom-photon quantum interface
Christoph Kurz, Pascal Eich, Michael Schug +2
We present the implementation of a programmable atom-photon quantum interface, employing a single trapped Ca ion and single photons. Depending on its mode of operation,…
Doubly-heralded single-photon absorption by a single atom
José Brito, Stephan Kucera, Pascal Eich +2
We report on a single-photon-to-single-atom interface, where a single photon generated by Spontaneous Parametric Down Conversion (SPDC) is absorbed by a single trapped ion. The pho…
Quantum interference in the absorption and emission of single photons by a single ion
Michael Schug, Christoph Kurz, Pascal Eich +3
We investigate quantum beats in the arrival-time distribution of single photons from a single trapped Ca ion, revealing their fundamentally different physical origins in…
Experimental protocol for high-fidelity heralded photon-to-atom quantum state transfer
Christoph Kurz, Michael Schug, Pascal Eich +3
A quantum network combines the benefits of quantum systems regarding secure information transmission and calculational speed-up by employing quantum coherence and entanglement to s…
Heralded photonic interaction between distant single ions
Michael Schug, Jan Huwer, Christoph Kurz +2
We establish heralded interaction between two remotely trapped single 40Ca+ ions through the exchange of single photons. In the sender ion, we release single photons with controlle…
A high-rate source for single photons in a pure quantum state
Christoph Kurz, Jan Huwer, Michael Schug +2
We report on the efficient generation of single photons, making use of spontaneous Raman scattering in a single trapped ion. The photons are collected through in-vacuum high-NA obj…
