Fabrication of Solid Immersion Lenses for the cryogenic Investigation of the NV center — •Judith de Vries, Katharina Senkalla, Stefan Dietel, Michael Olney-Fraser, Lev Kazak, and Fedor Jelezko — Institute for Quantumoptics, Ulm University, Ulm, Germany

The Nitrogen-Vacancy (NV) center in diamond has shown great potential for applications in quantum information processing, sensing, and imaging. A known application of NV center in cryogenic environment is the quantum repeater. As the entanglement rate is limited by the photon-collection efficiency of the NV centers, improving this efficiency through the use of solid immersion lenses can greatly enhance the performance of quantum repeaters. Here we investigate the performance of the fabricated SILs in particular in cryogenic environment.
