Sub-to-super-Poissonian photon statistics in cathodoluminescence of color center ensembles in isolated diamond crystals
Saskia Fiedler, Sergii Morozov, Danylo Komisar +8
Impurity-vacancy centers in diamond offer a new class of robust photon sources with versatile quantum properties. While individual color centers commonly act as single-photon sourc…
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…
Unidirectional single-photon emission from germanium-vacancy zero-phonon lines: Deterministic emitter-waveguide interfacing at plasmonic hot spots
Hamidreza Siampour, Ou Wang, Vladimir A. Zenin +10
Striving for nanometer-sized solid-state single-photon sources, we investigate atom-like quantum emitters based on single germanium vacancy (GeV) centers isolated in crystalline na…
Single Silicon Vacancy Centers in 10-Nanometer Diamonds for Quantum Information Applications
Stepan V. Bolshedvorskii, Anton I. Zeleneev, Vadim V. Vorobyov +12
Ultra-small, low-strain, artificially produced diamonds with an internal, active color center have substantial potential for quantum information processing and biomedical applicati…
On-chip excitation of single germanium-vacancies in nanodiamonds embedded in plasmonic waveguides
Hamidreza Siampour, Shailesh Kumar, Valery A. Davydov +3
Monolithic integration of quantum emitters in nanoscale plasmonic circuitry requires low-loss plasmonic configurations capable of confining light well below the diffraction limit.…
All-optical nanoscale thermometry with silicon-vacancy centers in diamond
Christian T. Nguyen, Ruffin E. Evans, Alp Sipahigil +7
We demonstrate an all-optical thermometer based on an ensemble of silicon-vacancy centers (SiVs) in diamond by utilizing a temperature dependent shift of the SiV optical zero-phono…
Experimental study of intrinsic multiple Andreev reflections effect in GdO(F)FeAs superconductor array junctions
