QuantWare, a Delft-based industrial quantum processor company, today announced a €152 million ($178 million) Series B round following the announcement of VIO-40K, a quantum processor architecture for 10,000 qubits, 100x larger than the state of the art today.
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. This allegedly marks the largest private round raised by a dedicated quantum processor company to date.
“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,” states 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.”
QuantWare’s Series B sits within a concentrated 2026 funding pattern around European quantum computing and the hardware layers necessaryed to scale it. EU-Startups has reported large rounds for eleQtron and Equal1, as well as several enabling-hardware raises covering quantum chip testing, photonics, cryogenic electronics and semiconductor lasers.
The Dutch context is especially relevant: Groove Quantum and OrangeQS, both Delft-based, have also raised funding in 2026, pointing to 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 financings and follows its previously reported €20 million Series A in 2025.
“In superconducting quantum computing, scale is increasingly constrained by routing, packaging, and manufacturability – not just qubit design,” states Kike Miralles, Intel Capital. “QuantWare recognised 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.”
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 – the QPU architecture to scale superconducting qubits to utility-scale quantum computing – for the entire ecosystem.
QuantWare states they have shipped more quantum processors than any other commercial supplier, serving more than 50 customers across 20 countries.
The company is also 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.
“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 indusattempt. 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,” declared Robin van Boxsel, General Partner at FORWARD.one.
The company states they are the only ones that design, fabricate, and integrate 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 indusattempt. QuantWare serves the global quantum supply chain through QuantWare-designed QPUs, foundry services, and chiplet packaging – enabling quantum computing companies to scale on QuantWare’s VIO architecture.
“Quantum computing is on the verge of an inflection point, and is a strategic priority for nations around the world,” adds 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.”
