Delft-based QuantWare has closed a €152 million ($178 million) Series B round — the largest private investment ever raised by a dedicated quantum processor company. The oversubscribed round was led by new investors Intel Capital, IQT, and ETF Partners, with existing backers FORWARD.one , Invest-NL Deep Tech Fund, InnovationQuarter Capital, Ground State Ventures, and Graduate Ventures also participating. QuantWare was founded in 2021 by Matt Rijlaarsdam and Alessandro Bruno as a spinout from QuTech at TU Delft. The company designs, fabricates, and integrates modular quantum processors on an open architecture — the only company to do all three at an industrial scale. It has shipped to more than 50 customers across 20 countries, making it the world's largest commercial quantum processor supplier by volume, serving quantum computing companies, national technology institutes, and major global technology conglomerates. Alongside the fundraise, QuantWare announced VIO-40K, a new quantum processor architecture capable of scaling to 10,000 qubits — roughly 100 times the current state of the art. The VIO platform is built as an open architecture, meaning other companies can use it to scale their own processor technology, turning QuantWare into a supply chain layer for the entire quantum computing industry. The capital will primarily fund KiloFab, a dedicated quantum processor factory being built in Delft that will increase QuantWare's production capacity by 20x. It also follows a €20 million Series A raised in 2025, and marks the largest Series B ever for a Dutch deep tech company. The funding comes as quantum computing edges toward an inflection point, with nations and enterprises racing to secure access to the hardware layer that underpins the entire sector.
