Dr. Matthias Widmann
Dr. Matthias Widmann is a researcher in silicon-carbide (SiC) spin defects, working at the boundary where quantum-hardware engineering meets condensed-matter physics. He helped turn that research into a company, and now works on what it takes for spin-based quantum sensing to survive real industrial workflows, not only the lab bench. On this site he writes as Coherence Times, a long-form notebook tracing where quantum technologies, AI, and industrial reality intersect — for researchers and for the people who deploy what they build.
Background
Matthias Widmann earned his doctorate at the University of Stuttgart, in the group of Jörg Wrachtrup, on optically addressable spin defects in silicon carbide. He is first author of the 2015 Nature Materials paper “Coherent control of single spins in silicon carbide at room temperature”, which demonstrated room-temperature coherent control of single SiC spins.
He then worked on diamond-based quantum processors at Quantum Brilliance.
Matthias Widmann was part of the founding team of Advanced Quantum (Stuttgart) — the company grew out of his research, and he shaped its first funded projects. Today he serves as its Chief Quantum Officer.
