Polarisation-independent Conversion of single photons from infrared to ultraviolet — •Alireza Aghababaei and Simon Stellmer — Nußallee 12, 53115 Bonn

Wavelength conversion at the single-photon level is required to forge a quantum network from distinct quantum devices. Such devices could include solid-state emitters of single or entangled photons, as well as network nodes based on atoms or ions. We convert single photons emitted from an III-V semiconductor quantum dot at 853nm via sum frequency conversion to the wavelength of the strong transition of Yb ions at 370nm. In this poster, we will present a sagnac setup that allows polarization-independent frequency conversion.
