QuantWare

Quantum computing remains largely a laboratory phenomenon. Quantum processors exist, demonstrations of quantum advantage have been achieved, but industrial-scale production of quantum hardware is not yet a reality. QuantWare, a Dutch startup based in Delft — the city that is also home to TU Delft and QuTech, two of the world's most advanced quantum research centers — has set out to address this bottleneck by building the first industrial-scale fab dedicated to quantum processor production. QuantWare's strategy starts from a distinctive architecture: modular VIO processors built on an open architecture, designed to be composable and interoperable, without the vendor lock-in that characterizes many proprietary solutions in the quantum space. This positioning matters because the quantum computing market is still at a stage where standardization is minimal and single-vendor dependency is a real risk for those looking to build on this hardware. The $178M Series B round — approximately €152M, the largest private round ever raised by a company dedicated to quantum processor manufacturing — will fund the construction of KiloFab, the world's first industrial-scale fab specifically designed for scalable quantum processor production. The name is deliberate: the goal is to produce processors with thousands of qubits in a reliable and repeatable fashion, moving quantum hardware from the logic of artisanal prototyping to the logic of industrial production. QuantWare's target market includes research labs, universities, quantum computing centers, and large technology operators that need modular, scalable quantum processors without depending on a single supplier. It is still a young market, but one with potentially explosive growth dynamics as commercial applications of quantum computing become real. QuantWare's significance in the European landscape extends beyond any single product: bringing industrial quantum hardware production to Europe means building a local supply chain for a technology that could be strategically critical over the next decade. The Delft ecosystem, with its unique concentration of quantum expertise, is the ideal environment for this ambition.
