Vanadium in Silicon Carbide: Telecom-ready spin centres with long relaxation lifetimes and hyperfine-resolved optical transitions
T. Astner, P. Koller, C. M. Gilardoni +6
Vanadium in silicon carbide (SiC) is emerging as an important candidate system for quantum technology due to its optical transitions in the telecom wavelength range. However, sever…
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…
Optical Properties of Vanadium in 4H Silicon Carbide for Quantum Technology
L. Spindlberger, A. Csóré, G. Thiering +7
We study the optical properties of tetravalent vanadium impurities in 4H silicon carbide (4H SiC). Emission from two crystalline sites is observed at wavelengths of 1.28 \mum and 1…
High-fidelity spin and optical control of single silicon vacancy centres in silicon carbide
Roland Nagy, Matthias Niethammer, Matthias Widmann +14
Optically interfaced spins in the solid promise scalable quantum networks. Robust and reliable optical properties have so far been restricted to systems with inversion symmetry. He…
Stark Tuning and Electrical Charge State Control of Single Divacancies in Silicon Carbide
Charles F. de las Casas, David J. Christle, Jawad Ul Hassan +3
Neutrally charged divacancies in silicon carbide (SiC) are paramagnetic color centers whose long coherence times and near-telecom operating wavelengths make them promising for scal…
Isolated spin qubits in SiC with a high-fidelity infrared spin-to-photon interface
David J. Christle, Paul V. Klimov, Charles F. de las Casas +11
The divacancies in SiC are a family of paramagnetic defects that show promise for quantum communication technologies due to their long-lived electron spin coherence and their optic…
Isolated electron spins in silicon carbide with millisecond-coherence times
David J. Christle, Abram L. Falk, Paolo Andrich +6
The elimination of defects from SiC has facilitated its move to the forefront of the optoelectronics and power-electronics industries. Nonetheless, because the electronic states of…
