Interference of single photons emitted by entangled atoms in free space
Gabriel Araneda, Daniel B. Higginbottom, Lukáš SlodiÄka +2
The generation and manipulation of entanglement between isolated particles has precipitated rapid progress in quantum information processing. Entanglement is also known to play an…
Probing surface charge densities on optical fibers with a trapped ion
Florian R. Ong, Klemens Schüppert, Pierre Jobez +8
We describe a novel method to measure the surface charge densities on optical fibers placed in the vicinity of a trapped ion, where the ion itself acts as the probe. Surface charge…
Femtosecond laser written waveguides in sapphire for visible light delivery
Sarah Winkler, Joachim R. Krenn, Jakob Wahl +8
A promising solution for scalable integrated optics of trapped-ion quantum processors are curved waveguides guiding visible light within sapphire bulk material. To the best of our…
Cavity-based single atom preparation and high-fidelity hyperfine state readout
Roger Gehr, Jürgen Volz, Guilhem Dubois +6
We prepare and detect the hyperfine state of a single 87Rb atom coupled to a fiber-based high finesse cavity on an atom chip. The atom is extracted from a Bose-Einstein condensate…
Strong atom-field coupling for Bose-Einstein condensates in an optical cavity on a chip
Yves Colombe, Tilo Steinmetz, Guilhem Dubois +3
An optical cavity enhances the interaction between atoms and light, and the rate of coherent atom-photon coupling can be made larger than all decoherence rates of the system. For s…
Wavelength-scale errors in optical localization due to spin-orbit coupling of light
Gabriel Araneda, Stefan Walser, Yves Colombe +4
The precise determination of the position of point-like emitters and scatterers using far-field optical imaging techniques is of utmost importance for a wide range of applications…
