A Quantum Repeater Platform based on Single SiV Centers in Diamond with Cavity-Assisted, All-Optical Spin Access and Fast Coherent Driving
Gregor Bayer, Robert Berghaus, Selene Sachero +8
Quantum key distribution enables secure communication based on the principles of quantum mechanics. The distance in fiber-based quantum communication is limited to about a hundred…
Hybrid quantum photonics based on artificial atoms placed inside one hole of a photonic crystal cavity
Konstantin G. Fehler, Lukas Antoniuk, Niklas Lettner +7
Spin-based quantum photonics promise to realize distributed quantum computing and quantum networks. The performance depends on efficient entanglement distribution, where the effici…
Preparing single SiV center in nanodiamonds for external, optical coupling with access to all degrees of freedom
Stefan Häußler, Lukas Hartung, Konstantin G. Fehler +6
Optical coupling enables intermediate- and long-range interactions between distant quantum emitters. Such interaction may be the basic element in bottom-up approaches of coupled sp…
Purcell-Enhanced Emission from Individual SiV Center in Nanodiamonds Coupled to a SiN-Based, Photonic Crystal Cavity
Konstantin G. Fehler, Anna P. Ovvyan, Lukas Antoniuk +6
Hybrid quantum photonics combines classical photonics with quantum emitters in a postprocessing step. It facilitates to link ideal quantum light sources to optimized photonic platf…
Single SiV centers in low-strain nanodiamonds with bulk-like spectral properties and nano-manipulation capabilities
Lachlan J. Rogers, Ou Wang, Yan Liu +7
We report on the isolation of single SiV centers in nanodiamonds. We observe the fine-structure of single SiV center with improved inhomogeneous ensemble linewidth below th…
