Bright single photon sources in lateral silicon carbide light emitting diodes
Matthias Widmann, Matthias Niethammer, Takahiro Makino +7
Single-photon emitting devices have been identified as an important building block for applications in quantum information and quantum communication. They allow to transduce and co…
Electrical charge state manipulation of single silicon vacancies in a silicon carbide quantum optoelectronic device
Matthias Widmann, Matthias Niethammer, Dmitry Yu. Fedyanin +14
Colour centres with long-lived spins are established platforms for quantum sensing and quantum information applications. Colour centres exist in different charge states, each of th…
Coherent electrical readout of defect spins in 4H-SiC by photo-ionization at ambient conditions
Matthias Niethammer, Matthias Widmann, Torsten Rendler +11
Quantum technology relies on proper hardware, enabling coherent quantum state control as well as efficient quantum state readout. In this regard, wide-bandgap semiconductors are an…
Faraday Filtering on the Cs-D-Line for Quantum Hybrid Systems
Matthias Widmann, Simone Portalupi, Sang-Yun Lee +3
Narrow-band filtering of light is widely used in optical spectroscopy. Atomic filters, which rely on the Faraday effect, allow for GHz-wide transmission spectra, which are intrinsi…
