Optical Integration of single NV-centers for Quantum Computing and Sensing
- Single Nitrogen-Vacancy centers (NV-centers) in diamond can be operated at ambient conditions as qubits in quantum memories and nanoscale quantum sensors. At TH Nürnberg, we plan to deterministically generate single NV-centers via femtosecond-laser pulses and integrate them into photonic platforms via 3D-printed microoptics and fs-written waveguides. This presentation gives a summary about our activites: The design and analysis of micro-lens systems to be manufactured via Two-Photon Polymerization on top of individual, self-written NV-centers for increased photon-collection efficiency, the programming of a spatial light modulator for wavefront optimization, the setup of a confocal scanning fluorescence microscope that addresses individual NV-Centers and laser material processing that allows to shape the diamond surface and to fabricate waveguides in the diamond for efficient optical coupling.
