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…
Spectrally stable defect qubits with no inversion symmetry for robust spin-to-photon interface
Péter Udvarhelyi, Roland Nagy, Florian Kaiser +3
Scalable spin-to-photon interfaces require quantum emitters with strong optical transition dipole moment and low coupling to phonons and stray electric fields. It is known that par…
Robust and efficient control of spin probes in a complex (biological) environment. Towards sensing of fast temperature fluctuations
Philipp Konzelmann, Torsten Rendler, Ville Bergholm +9
We present an optimized scheme for nanoscale measurements of temperature in a complex environment using the nitrogen-vacancy center in nanodiamonds. To this end we combine a Ramsey…
Modulation frequency dependence of continuous-wave optically/electrically detected magnetic resonance
Sang-Yun Lee, Seoyoung Paik, Dane R. McCamey +1
Continuous wave optically and electrically detected magnetic resonance spectroscopy (cwODMR/cwEDMR) allow the investigation of paramagnetic states involved in spin-dependent transi…
