Quantware banked €166.7M ($178M) in a Series B round co-led by Intel Capital and Forward.One. The fundraise also saw participation from IQT, ETF Partners, and existing Dutch backers including Invest-NL and Innovation Quarter.
The Delft-based startup designs and manufactures processors for quantum computers. Its core technology addresses the "wiring bottleneck" that limits qubit density by using a proprietary architecture that routes signals more efficiently. This internal design allows for chips that are 100 times more qubit-dense than traditional alternatives, supporting the industry's push toward machines with hundreds of thousands of qubits.
Quantware operates a dual business model: it sells its own superconducting processors to research institutes and tech firms, while also allowing third-party manufacturers to use its architecture for their own chips. The new capital is earmarked for an industrial-scale fabrication facility in the Netherlands, designed to increase production capacity twentyfold to meet demand from more than 50 global customers.
As quantum hardware moves from laboratory experiments to industrial production, European specialists are increasingly securing the nine-figure "megarounds" required to compete with well-funded incumbents in the US and China.
