QuantWare Raises $178M for 10,000-Qubit Processor

Jan de Vries · 2026-05-05

QuantWare, a Delft-based company that builds industrial quantum processors, just announced a massive $178 million Series B round. That's right on the heels of their VIO-40K reveal, a new quantum processor architecture designed to handle 10,000 qubits. To put that in perspective, it's 100 times larger than anything else on the market today. New investors in this round include Intel Capital, IQT, and ETF Partners. They're joining existing backers like FORWARD.one, Invest-NL Deep Tech Fund, InnovationQuarter Capital, Ground State Ventures, and Graduate Ventures. The company claims this is the largest private funding round ever for a dedicated quantum processor company. ### What This Means for Quantum Computing "The promise of quantum computing, capable of solving humanity's intractable challenges, can only happen once it can be manufactured and deployed at scale," says Matt Rijlaarsdam, CEO and co-founder of QuantWare. "That is exactly what we are building." He explains that VIO-40K will deliver 10,000-qubit processors on an open architecture that the entire ecosystem can build on. And KiloFab, their new fab, gives them 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. ### The Bigger Picture in European Quantum Computing QuantWare's Series B is part of a concentrated 2026 funding pattern around European quantum computing. Other startups like eleQtron and Equal1 have also raised large rounds. We're seeing enabling-hardware raises covering quantum chip testing, photonics, cryogenic electronics, and semiconductor lasers. The Dutch context is especially relevant here. Groove Quantum and OrangeQS, both also Delft-based, have raised funding in 2026 too. That points to serious local activity around quantum chip manufacturing, validation, and infrastructure. Against this backdrop, QuantWare's round is materially larger than any other 2026 quantum-related startup financing. It follows their previously reported $21.8 million Series A in 2025. ### Why Intel Capital Invested "In superconducting quantum computing, scale is increasingly constrained by routing, packaging, and manufacturability – not just qubit design," says Kike Miralles from 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." ### Company Background and Technology Founded in 2021 by Matt Rijlaarsdam and Alessandro Bruno as a spinout from QuTech at TU Delft, QuantWare designs, fabricates, and integrates quantum processors on VIO. That's their QPU architecture designed to scale superconducting qubits to utility-scale quantum computing for the entire ecosystem. QuantWare says they've shipped more quantum processors than any other commercial supplier, serving more than 50 customers across 20 countries. They're also building KiloFab, the world's largest dedicated quantum open architecture fab, which will increase their production capacity by 20 times to meet strong global customer demand. ### Investor Confidence and Future Plans "Building a global compute hardware company requires immense ambition," says Robin van Boxsel, General Partner at FORWARD.one. "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." The company claims they're the only ones that design, fabricate, and integrate modular quantum processors on an open architecture at an industrial scale. Their 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, and this funding will help them accelerate their roadmap significantly.
