DELFT, Netherlands, May 05, 2026 -- QuantWare, the leading industrial quantum processor company, today announced a $178 million (€152 million) Series B equity funding following the announcement of VIO-40K, a quantum processor architecture for 10,000 qubits, 100x larger than the state of the art today. The company is building KiloFab, the world’s largest dedicated quantum open architecture fab, increasing the company’s production capacity by 20x to meet strong global customer demand.

QuantWare is the only company that designs, fabricates, and integrates modular quantum processors on an open architecture at an industrial scale. Its proprietary VIO technology — a modular Quantum Processor Architecture — allows the creation of the world’s most powerful quantum processors that provide the most compute per Watt.

Designed as an open platform that can scale the qubit chiplets and designs of third parties, VIO unlocks the most powerful quantum processing units (QPUs) for the entire industry. QuantWare serves the global quantum supply chain through QuantWare-designed QPUs, foundry services, and chiplet packaging — enabling all quantum computing companies to scale on QuantWare’s VIO architecture.

To date, QuantWare has shipped to more than 50 customers across 20 countries, making it the world’s largest commercial QPU supplier by volume. QuantWare's customers span quantum computing companies, national technology institutes, and major global technology conglomerates.

New investors joining the round include Intel Capital, IQT and ETF Partners, with existing investors participating including FORWARD.one and Invest-NL Deep Tech Fund, InnovationQuarter Capital, Ground State Ventures, and Graduate Ventures. The round was heavily oversubscribed and is the largest private round raised by a dedicated quantum processor company to date.

“In superconducting quantum computing, scale is increasingly constrained by routing, packaging, and manufacturability—not just qubit design,” said Kike Miralles, Intel Capital. “QuantWare recognized that early and built VIO to address it. That combination of technical ambition and execution positions them to become the company on which the future of superconducting quantum systems will be built.”

"Building a global compute hardware company requires immense ambition. The QuantWare team has that drive, and with their VIO technology, they hold the key to leading the high-growth quantum industry. As one of their earliest backers, we are proud to continue our support in what is now the world’s largest funding round for a dedicated quantum processor company," said Robin van Boxsel, General Partner at FORWARD.one.

“Quantum computing is on the verge of an inflection point, and is a strategic priority for nations around the world,” said J.D. Englehart, Senior Director, IQT. “QuantWare has both the breakthrough scaling technology in VIO, as well as the requisite industrial capability in KiloFab. The company is poised to play a key role in shaping the global quantum supply chain.”

"The promise of quantum computing, capable of solving humanity's intractable challenges, can only happen once it can be manufactured and deployed at scale. That is exactly what we are building," said Matt Rijlaarsdam, CEO and co-founder of QuantWare. "VIO-40K will deliver 10,000-qubit processors on an open architecture that the entire ecosystem can build on, and KiloFab gives us the industrial production capacity to meet rapidly growing global demand. This fundraise accelerates QuantWare, and in doing so, advances the entire ecosystem toward hyperscale quantum compute."
