QuantWare has raised $178 million (€152 million) in a Series B funding round to accelerate the development of large-scale quantum processors and expand manufacturing capacity, positioning itself at the forefront of industrial quantum computing.
QuantWare is a dedicated quantum processor company, founded in 2021 by Matt Rijlaarsdam and Alessandro Bruno as a spinout from QuTech at TU Delft. Since its inception, the company has focused on enabling scalable quantum hardware through modular architectures and industrial manufacturing approaches.
The funding follows the company’s recent announcement of VIO-40K, a quantum processor architecture designed to support up to 10,000 qubits—significantly larger than current industry benchmarks. The round is the largest private investment secured by a dedicated quantum processor company to date, reflecting growing investor confidence in scalable quantum technologies.
Proceeds from the funding will support the development of KiloFab, a dedicated quantum fabrication facility aimed at increasing production capacity by 20 times. The facility is intended to meet rising global demand for quantum processing units (QPUs) as enterprises, research institutions, and governments expand investments in quantum computing.
QuantWare differentiates itself through its modular quantum processor architecture, known as VIO. The platform is designed as an open architecture, allowing third-party developers to build and scale quantum systems using chiplet-based designs. This approach addresses key industry challenges such as routing complexity, packaging constraints, and manufacturability.
The company said its VIO architecture enables higher compute performance per watt while supporting flexible system integration. By offering QPU design, foundry services, and chiplet packaging, QuantWare is positioning itself as a supplier across the broader quantum ecosystem.
To date, the company has shipped to more than 50 customers across 20 countries. Its customer base includes quantum computing firms, national technology institutes, and global technology companies. QuantWare states it is the largest commercial supplier of QPUs by volume.
The funding round attracted new investors, including Intel Capital, IQT, and ETF Partners, alongside continued participation from existing backers such as FORWARD.one, Invest-NL Deep Tech Fund, InnovationQuarter Capital, Ground State Ventures, and Graduate Ventures. The round was reported to be oversubscribed.
Investors highlighted the importance of addressing system-level challenges in quantum computing. Kike Miralles of Intel Capital noted that scaling superconducting systems depends not only on qubit design but also on packaging and manufacturability. He said QuantWare’s approach positions it to play a central role in future quantum systems.
J.D. Englehart of IQT said the sector is approaching an inflection point, with companies that combine scalable technology and industrial capability expected to shape the global quantum supply chain.
Matt Rijlaarsdam, CEO and co-founder of QuantWare, said the company is focused on enabling quantum computing at scale. He added that the VIO-40K architecture and KiloFab facility are designed to support the transition from experimental systems to large-scale, commercially viable quantum infrastructure.
