QuantWare Raises $178M Series B to Scale Quantum Processor Production

QuantWare, a leading industrial quantum processor company based in Delft, the Netherlands, announces a $178 million (€152 million) Series B equity funding round. The financing, led by Intel Capital with participation from IQT, ETF Partners, FORWARD.one, and other investors, will accelerate the company’s development of its VIO-40K™ quantum processor architecture and the expansion of KiloFab, the world’s largest dedicated quantum open architecture fabrication facility.

The new funding round is the largest private equity raise by a dedicated quantum processor company to date and was heavily oversubscribed. QuantWare plans to use the capital to increase its production capacity by 20 times, enabling it to meet strong global demand from over 50 customers across 20 countries. These customers include quantum computing companies, national technology institutes, and major technology conglomerates.

Founded in 2021 as a spinout from QuTech at TU Delft, QuantWare designs, fabricates, and integrates modular quantum processors using its proprietary VIO™ technology. This modular Quantum Processor Architecture allows for scalable superconducting qubit chiplets on an open platform, enabling the creation of powerful quantum processing units (QPUs) that deliver high compute performance per watt. The VIO-40K™ processor architecture targets 10,000 qubits, representing a 100-fold increase over current state-of-the-art quantum processors.

QuantWare is unique in the quantum computing industry as it combines design, fabrication, and integration capabilities at an industrial scale. The company’s KiloFab facility will be the largest dedicated quantum open architecture fab globally, supporting the scaling of quantum processor production and enabling third-party designs to be integrated on the VIO™ platform.

Intel Capital, the lead investor, has a long history of investing in frontier technologies, having deployed over $20 billion in the tech ecosystem. IQT, a strategic investor focused on national security technologies, and ETF Partners, a European venture capital firm specializing in sustainability and impact investing, also joined the round. FORWARD.one, a venture capital firm dedicated to industrial technology, participated alongside existing investors including Invest-NL Deep Tech Fund, InnovationQuarter Capital, Ground State Ventures, and Graduate Ventures.

Industry experts highlight that scaling superconducting quantum computing is constrained not only by qubit design but also by routing, packaging, and manufacturability. QuantWare’s VIO™ architecture addresses these challenges by enabling modular, scalable quantum processors. The company’s approach positions it as a key player in the future of superconducting quantum systems.

The quantum computing market is approaching an inflection point, with hyperscale quantum compute becoming a strategic priority for governments and corporations worldwide. QuantWare’s expanded production capacity and open architecture platform aim to accelerate the commercialization of quantum processors and support the broader quantum ecosystem.

Financial details such as valuation and stake percentages were not disclosed. The company has shipped more quantum processors than any other commercial supplier by volume, reinforcing its market leadership. The new funding will support further product development, scaling manufacturing operations, and expanding foundry and chiplet packaging services.

Looking ahead, QuantWare plans to integrate third-party qubit chiplets on its VIO™ platform and leverage KiloFab’s increased capacity to meet growing demand. The company will also focus on managing intellectual property and collaboration risks inherent in its open architecture model while aligning global customer support and supply chain logistics.

This funding round strengthens QuantWare’s competitive position, prompting rivals to accelerate their own scaling and integration efforts. The company’s growth is expected to drive innovation and consolidation within the quantum computing industry.
