Listen to the episodeAbout QuantumDiamonds
QuantumDiamonds is a deep-tech startup founded in 2022 in Munich, spun out of the German university ecosystem. The company builds semiconductor inspection tools based on quantum sensing with nitrogen-vacancy (NV) centres in diamonds. The technology detects magnetic defects, mechanical stress and spin anomalies in wafers at nanometre scale, with the aim of improving yield and quality control during chip production. In July 2026, it announced €91M in total funding: €15M in equity led by World Fund alongside Bayern Kapital, IQ Capital, Earlybird, First Momentum, UnternehmerTUM, Creator Fund and Onsight Ventures, plus €76M in non-dilutive funding from German and European public sources. This is among the largest quantum hardware rounds in Europe in 2026.

- Nanometre-scale defect detection
- Non-destructive inspection
- Yield improvement in live production environments
How QuantumDiamonds grows
Growth Strategy
Scale inspection tool deployment to European semiconductor fabs and expand into global semiconductor supply chain.
Distribution Model
Direct B2B sales to semiconductor manufacturers and fabs.
Moat (Defensibility)
Proprietary quantum sensing technology based on diamond NV centres, production integration know-how and public funding anchoring German and European strategic interest.
Regulatory Context
Relevant to the European Chips Act, semiconductor sovereignty policy and dual-use technology regulation.
Key Risks
- Long hardware integration cycles
- Semiconductor market cyclicality
- Competition from established metrology vendors
- Scaling quantum hardware to production environments
Strategic Insights
- Quantum sensing is moving out of laboratories to become an industrial tool measurable in terms of yield and production costs.
- The equity plus non-dilutive public funding mix is a typical pattern for European deep-tech companies with a strategic or dual-use component.
- Inspection is a critical point in the chip supply chain: controlling inspection means controlling part of a fab's competitiveness.
Funding & Investors
Total Funding
Funding Rounds
- 2026 - Equity round: €15M equity
Lead: World Fund - 2026 - Non-dilutive public funding: €76M non-dilutive

Key Metrics
Lessons from QuantumDiamonds
- Quantum sensing becomes defensible when it produces measurable industrial outputs: yield, defects caught, costs avoided.
- European non-dilutive funding is a strategic resource for deep-tech companies with long runways and high capex.
- Choosing a supply-chain bottleneck as an entry market reduces adoption risk.
