QuantumDiamonds, a Munich-based semiconductor testing startup, has secured €15 million in equity funding led by World Fund, marking its first significant equity round. This capital injection, which complements €76 million in non-dilutive EU-backed state funding, will be used to scale production of its quantum sensing technology and expand its new testing facility. The company, currently employing 70 people, plans to more than double its engineering team within the next year, with existing deployments in the U.S. and Taiwan.
