QuantumDiamonds

QuantumDiamonds builds diamond-based quantum-sensing systems for non-destructive semiconductor inspection and failure analysis.

QuantumDiamonds GmbH was founded in 2022 by Kevin Berghoff and Fleming Bruckmaier as a spinout from the Technical University of Munich. Its founding team says it set out to commercialize diamond-based quantum sensing. The company builds semiconductor inspection and failure-analysis tools using quantum diamond microscopy. Its systems use diamond sensors to image electrical activity and locate defects in chips without destructive analysis. In December 2023, QuantumDiamonds secured a €7 million seed round. It launched its QDm.0 microscope in December 2024. On July 9, 2026, it announced a €91 million financing package, including a €15 million equity round and €76 million in non-dilutive funding. QuantumDiamonds applies quantum sensing to semiconductor testing. Its website describes its in-lab inspection system as commercially available and its in-line wafer-mapping system as under development.
