High-fidelity entanglement between a trapped ion and a telecom photon via quantum frequency conversion
Matthias Bock, Pascal Eich, Stephan Kucera +4
Entanglement between a stationary quantum system and a flying qubit is an essential ingredient of a quantum-repeater network. It has been demonstrated for trapped ions, trapped ato…

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…
