Precision frequency-comb terahertz spectroscopy on pure quantum states of a single molecular ion
Chin-wen Chou, Alejandra L. Collopy, Christoph Kurz +7
Spectroscopy is a powerful tool for studying molecules and is commonly performed on large thermal molecular ensembles that are perturbed by motional shifts and interactions with th…
Preparation and coherent manipulation of pure quantum states of a single molecular ion
Chin-wen Chou, Christoph Kurz, David B. Hume +3
Laser cooling and trapping of atoms and atomic ions has led to numerous advances including the observation of exotic phases of matter, development of exquisite sensors and state-of…
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…
