Controlling photon polarisation with a single quantum dot spin
Elham Mehdi, Manuel Gundin-Martinez, Clément Millet +9
In the framework of optical quantum computing and communications, a major objective consists in building receiving nodes that implement conditional operations on incoming photons,…
Heating of a trapped ion induced by dielectric materials
Markus Teller, Dario A. Fioretto, Philip C. Holz +8
Electric-field noise due to surfaces disturbs the motion of nearby trapped ions, compromising the fidelity of gate operations that are the basis for quantum computing algorithms. W…
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…
Indistinguishable photons from a trapped-ion quantum network node
M. Meraner, A. Mazloom, V. Krutyanskiy +7
Trapped atomic ions embedded in optical cavities are a promising platform to enable long-distance quantum networks and their most far-reaching applications. Here we achieve and ana…
Ion-based nondestructive sensor for cavity photon numbers
Moonjoo Lee, Konstantin Friebe, Dario A. Fioretto +7
We dispersively couple a single trapped ion to an optical cavity to extract information about the cavity photon-number distribution in a nondestructive way. The photon-number-depen…
