Munich, July 9, 2026
The Munich semiconductor start-up Quantum Diamonds has raised 91 million euros in a financing round, 76 million of which comes from the European chip funding program, the European Chips Act.
Founded in 2022, Quantum Diamonds combines quantum sensor technology with imaging processes based on synthetic diamonds. The technology uses so-called nitrogen vacancies in the diamonds to measure magnetic fields optically and with very high precision. This makes it possible to non-destructively detect defects in complex three-dimensional chip architectures that remain invisible with conventional methods.
Diamonds against chip scrap
Even the smallest production defects or contamination can render entire batches unusable, according to the company. Modern microchips – as required in smartphones, cars or for artificial intelligence applications – are highly complex, three-dimensional landscapes in miniature format. Quantum Diamonds' measurement technology operates at the nanometer scale.
