QuantWare, a Delft-based startup developing and manufacturing superconducting quantum processors, has raised a €152 million Series B round as investors continue to back companies building the infrastructure for large-scale quantum computing.

The round includes new investors Intel Capital, In-Q-Tel and ETF Partners, alongside existing backers FORWARD.one, Invest-NL Deep Tech Fund, InnovationQuarter Capital, Ground State Ventures and Graduate Ventures.

The company said the funding will be used to scale its quantum processor technology, expand manufacturing capacity, advance its VIO architecture and support the build-out of KiloFab, a dedicated quantum manufacturing facility in the Netherlands. The investment is aimed at helping QuantWare move further from research-led development toward industrial and commercial deployment.

Founded by Matt Rijlaarsdam and Alessandro Bruno, QuantWare is part of a growing group of European quantum hardware startups seeking to prove that the sector’s next challenge is not only scientific progress, but manufacturing at scale.
