Dutch quantum hardware company QuantWare raised $178 million in Series B funding to expand production of its superconducting quantum processors and scale its modular VIO quantum processor architecture.
The funding round follows the company’s recent announcement of VIO-40K, an architecture designed to support quantum processors with up to 10,000 qubits. QuantWare said its proprietary VIO architecture is designed to link modular superconducting quantum chiplets into larger quantum processors, an approach intended to address scaling bottlenecks around routing, packaging, and manufacturability.
The latest funding round included participation from Intel Capital and In-Q-Tel, alongside existing investors including FORWARD.one and Invest-NL Deep Tech Fund.
QuantWare said the funding would also support construction of the KiloFab fabrication facility, which it claims will be the world’s largest dedicated open-architecture quantum fabrication facility and increase production capacity by 20-times as demand for quantum processors grows.
QuantWare was founded as a spinout from QuTech at Delft University of Technology, and develops superconducting quantum processors and related fabrication and packaging technologies for the broader quantum computing ecosystem. It positions itself as a supplier to the wider quantum hardware market through processor sales, foundry services, and chiplet packaging, with VIO intended to function as an open platform capable of integrating third-party chiplets and qubit designs.
“In superconducting quantum computing, scale is increasingly constrained by routing, packaging, and manufacturability – not just qubit design,” Intel Capital's Kike Miralles noted in a statement.
The funding announcement reflects growing industry focus on the manufacturing and supply-chain challenges associated with scaling quantum hardware beyond laboratory-scale systems. While much of the quantum industry remains focused on qubit fidelity and error correction, companies are increasingly confronting practical engineering constraints around interconnect density, cryogenic packaging, fabrication yield, and system integration.
QuantWare claims to have shipped processors to more than 50 customers across 20 countries, including quantum computing companies, national research institutes, and large technology firms.
The company did not disclose revenue figures or production volumes.
