Single-ion Faraday rotation and ion-ion entanglement by single-photon detection — •Gabriel Araneda Machuca1, Lukas Slodicka2, Nadia Röck1, Gabriel Hétet1, Markus Hennrich1, Yves Colombe1, and Rainer Blatt1 — 1Universität Innsbruck — 2Palacky University, Olomuc
We present two recent experiments with one and two trapped Barium ions. In the first [1] we could observe Faraday rotation of a probed beam by a single trapped ion. In the second one [2] we were able to entangle two effectively distant ions by a single photon detection triggered process.
Furthermore, we present the development of our new ion trap, which is composed by four main tips and integrated with a hemispherical mirror and a high numerical aperture (0.7) aspheric lens. This new trap will allow us to more than triple our collection of fluorescence light, and to explore a regime where the spontaneous emission of the ion can be reduced drastically.
