Delft, Tuesday, 5 May 2026.
QuantWare’s groundbreaking Series B marks the largest private investment ever raised by a dedicated quantum processor company, positioning the Netherlands-based startup to revolutionize quantum computing through industrial-scale manufacturing. The funding will accelerate development of their ambitious VIO-40K architecture capable of handling 10,000 qubits—100 times larger than current quantum processors—and support construction of KiloFab, the world’s largest quantum fabrication facility that will increase production capacity twentyfold by 2026.

Quantum Computing Technology at Industrial Scale

This development centers squarely on quantum computing technology, specifically the design and manufacturing of quantum processing units (QPUs) at unprecedented scale [1][2]. QuantWare operates as an industrial quantum processor company that designs, fabricates, and integrates modular quantum processors on an open architecture platform [3]. The company’s breakthrough lies in addressing quantum computing’s fundamental scaling challenges through its proprietary VIO™ technology, which enables the creation of hyperscaled quantum processors delivering enhanced compute efficiency per watt [3]. Unlike traditional semiconductor manufacturing focused on classical computing chips, QuantWare’s quantum processors utilize superconducting qubits—quantum bits that can exist in multiple states simultaneously, enabling exponentially more powerful computational capabilities than classical processors [GPT].

Revolutionary VIO Architecture and Its Benefits

The innovation’s core benefits stem from QuantWare’s VIO™ architecture, which addresses the critical scaling limitations that have constrained quantum computing development. The VIO architecture routes 40,000 signal lines within a compact 15x15cm module, enabling processors with up to 10,000 qubits [4]. This represents a dramatic leap from current capabilities, as CEO Matt Rijlaarsdam explained the scaling challenge: “If you wanted to get to 1m qubits, you’d need a chip the size of Central Park. That’s not going to scale” [6]. The VIO-40K™ processors will be 100 times larger than current state-of-the-art quantum processors [8], addressing what Intel Capital’s Kike Miralles identified as the industry’s core constraint: “In superconducting quantum computing, scale is increasingly constrained by routing, packaging, and manufacturability—not just qubit design” [1][2]. The open architecture approach allows third-party quantum companies to build upon QuantWare’s platform, accelerating the entire quantum ecosystem’s development [1].

Leadership and Geographic Foundation

QuantWare was co-founded in 2021 by CEO Matt Rijlaarsdam and CTO Alessandro Bruno as a spinout from QuTech at TU Delft [1][4][5]. The company maintains its headquarters in Delft, the Netherlands [2][5], positioning the Dutch quantum ecosystem at the forefront of global quantum technology development. Under Rijlaarsdam’s leadership, the company has established itself as a significant commercial player, having shipped quantum processors to more than 50 customers across 20 countries [1][2][5][6]. The leadership team has been strengthened with strategic additions including Jean-Pierre Pennacino, formerly of Motorola and ST Micro, as CFO, and Aparna Prabhakar, former IBM Quantum VP, as a board member [4]. This Dutch-based operation has emerged from one of Europe’s premier quantum research institutions, leveraging the academic foundation of QuTech to build commercial quantum processing capabilities.

Funding Details and Market Positioning

The €152 million ($178 million) Series B funding round, announced on May 4, 2026, represents the largest private investment ever secured by a dedicated quantum processor company [1][2][3]. The round was co-led by Intel Capital and Dutch VC Forward.One, with new investors including IQT (In-Q-Tel), ETF Partners, alongside existing investors FORWARD.one, Invest-NL Deep Tech Fund, Innovation Quarter Capital, Ground State Ventures, and Graduate Ventures [6][8]. This funding arrives amid explosive growth in quantum computing investment, with the sector experiencing 374 percent year-over-year growth to $4.53 billion in 2025 [4]. The quantum computing market itself is valued at $2.04 billion in 2026 and projected to reach $18.33 billion by 2034, representing a compound annual growth rate of 31.6 percent [4]. The funds will specifically support QuantWare’s KiloFab facility construction and accelerate development of the VIO-40K processors, with first shipments planned for 2028 [4][6], while the KiloFab production facility is scheduled to open in 2026 to increase production capacity by 20 times [1][2][6].
