QuantWare, the industrial quantum processor company, has closed a $178 million Series B equity funding round to accelerate its VIO™ processor architecture and to fund the construction of KiloFab, the world’s largest dedicated quantum open-architecture fabrication facility. The round marks the largest private funding round ever raised by a dedicated quantum processor company. New investors include Intel Capital, In-Q-Tel, and ETF Partners, joined by existing backers FORWARD.one, Invest-NL Deep Tech Fund, InnovationQuarter Capital, Ground State Ventures, and Graduate Ventures.
QuantWare’s proprietary VIO™ technology is a modular Quantum Processor Architecture that enables the creation of processors delivering the most compute per watt. The company recently announced VIO-40K™, a quantum processor architecture targeting 10,000 qubits — 100 times larger than the current state of the art. Designed as an open platform, VIO™ supports third-party qubit chiplet designs, enabling the entire quantum computing ecosystem to build on QuantWare’s architecture.
The KiloFab facility will increase QuantWare’s production capacity by 20 times to meet growing global customer demand. Founded as a spinout from QuTech at TU Delft in 2021, the company has already shipped quantum processors to more than 50 customers across 20 countries, making it the largest commercial QPU supplier by volume. Customers span quantum computing companies, national technology institutes, and major global technology conglomerates.
The round was heavily oversubscribed, reflecting broad investor conviction in the quantum computing sector as it approaches what many in the industry describe as an inflection point. QuantWare is headquartered in Delft, the Netherlands, and was co-founded by CEO Matt Rijlaarsdam and Alessandro Bruno.
KEY QUOTES:
“In superconducting quantum computing, scale is increasingly constrained by routing, packaging, and manufacturability — not just qubit design. 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.”
Kike Miralles, Intel Capital
“Quantum computing is on the verge of an inflection point and is a strategic priority for nations around the world. 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.”
J.D. Englehart, Senior Director, IQT
“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. 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.”
Matt Rijlaarsdam, CEO and Co-Founder, QuantWare
