QuantumDiamonds (QD) is a Munich-based German deep-tech company that develops diamond-based quantum sensing systems for semiconductor inspection and failure analysis. The company markets what it describes as the world's first commercially available quantum sensing system for semiconductor inspection, using nitrogen-vacancy (NV) diamond quantum microscopy to detect defects and current-flow anomalies that traditional inspection methods miss. QuantumDiamonds is a portfolio company of the venture firm Earlybird and was added to the API Evangelist network as a company profile. As a quantum hardware and instrumentation company, it does not currently expose a public developer API, SDK, or developer portal; this profile captures its public web presence and company identity.
