Coherence and Entanglement Preservation of Frequency-Converted Heralded Single Photons
Andreas Lenhard, José Brito, Matthias Bock +2
We report on quantum frequency conversion of near-infrared photons from a wavelength of 854nm to the telecommunication O-band at 1310nm with 8% overall conversion efficiency. Entan…

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 and classical telecommunication channel multiplexing
Andreas Lenhard, José Brito, Stephan Kucera +3
We demonstrate the multiplexing of a classical coherent and a quantum state of light in a single telecommunciation fiber. For this purpose we make use of spontaneous parametric dow…
