Dutch quantum processor company QuantWare announced on Monday a $178 million Series B funding round — the largest private raise ever by a dedicated quantum processor company — to construct a high-volume fabrication facility in Delft and advance its architecture toward 10,000-qubit chips.
Inside the Round
The oversubscribed round drew new investors Intel Capital, IQT (the investment arm of In-Q-Tel, the U.S. national security community’s strategic venture fund), and ETF Partners, alongside existing backers FORWARD.one, Invest-NL Deep Tech Fund, InnovationQuarter Capital, Ground State Ventures, and Graduate Ventures. Reuters reported that the deal reflects Europe’s efforts to keep pace with quantum advances from the U.S. and China.
The capital will fund KiloFab, which QuantWare describes as the world’s largest dedicated quantum open architecture fabrication facility. Scheduled to open this year at the company’s Delft headquarters, KiloFab is designed to increase production capacity by 20 times. The facility will manufacture processors based on QuantWare’s proprietary VIO-40K architecture, which uses a 3D scaling approach supporting 40,000 input/output lines via interconnected chiplet modules to reach 10,000 qubits — 100 times beyond current commercial systems. Initial shipments of VIO-40K processors are expected in 2028, with each 10,000-qubit chip estimated to cost roughly €50 million.
“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.
A Horizontal Play on Quantum Hardware
Founded in 2021 as a spinout from QuTech at TU Delft by Rijlaarsdam and Alessandro Bruno, QuantWare has positioned itself not as a quantum computer builder but as a horizontal supplier to the broader industry — offering its own QPU designs, foundry services, and chiplet packaging on an open architecture. The company has shipped quantum processors to more than 50 customers across 20 countries, including quantum computing companies, national technology institutes, and major technology conglomerates.
“QuantWare recognized that early and built VIO to address it,” said Kike Miralles of Intel Capital. “That combination of technical ambition and execution positions them to become the company on which the future of superconducting quantum systems will be built.”
The raise comes amid a surge in quantum computing investment, with sector funding rising 374 percent year-over-year to $4.53 billion in 2025, according to TamRadar. Finnish competitor IQM raised $57 million from BlackRock funds in March ahead of a planned U.S. IPO.
