European quantum computing has just received one of its biggest signals of industrial ambition. QuantWare, a Dutch company spun out of QuTech at Delft University of Technology, has closed a $178 million Series B round, approximately €152 million, to accelerate the development of its superconducting quantum processors and expand its manufacturing capacity.
The operation includes participation from Intel Capital, In-Q-Tel, ETF Partners, and several existing investors, such as FORWARD.one, Invest-NL Deep Tech Fund, QDNL Participations, and Graduate Ventures. According to the company, this is the largest private funding round raised to date by a company dedicated specifically to industrial quantum processors. The funding follows the announcement of VIO-40K, an architecture through which QuantWare aims to reach processors with 10,000 qubits—a scale the company claims is 100 times larger than the current state of the art.
The challenge is no longer just building better qubits
For years, much of the debate surrounding quantum computing has focused on qubit quality: fidelity, stability, coherence time, and noise resistance. All of these remain essential. But as the industry seeks to move from experimental processors to systems with commercial utility, the bottleneck is increasingly shifting toward more physical and industrial issues: wiring, interconnection, packaging, repeatable manufacturing, and the ability to integrate thousands of qubits without making the system unmanageable.
This is precisely the issue that attracted Intel Capital’s interest. Kike Miralles, an investor from the firm, summarizes the thesis clearly: in superconducting quantum computing, scale is increasingly limited by routing, packaging, and manufacturability, not just qubit design. QuantWare, according to Intel Capital, quickly identified this problem and developed VIO to address it.
VIO is QuantWare’s modular architecture for quantum processors. The company describes it as an open platform capable of scaling quantum chiplets from both its own and third-party designs. Instead of betting on a closed, fully integrated stack, QuantWare aims to provide an industrial foundation upon which other ecosystem players can build. This approach is significant because the quantum market remains fragmented across labs, startups, tech giants, national institutes, and specialized suppliers.
The promise of VIO-40K is ambitious: an architecture designed for 10,000 qubits and 40,000 I/O lines. The goal is not just to increase qubit count but also to create processors that can be manufactured and integrated at an industrial scale. The company also mentions higher compute per watt—a metric that could gain importance if quantum systems transition from scientific prototypes to real infrastructures with critical considerations like power consumption, maintenance, and availability.
KiloFab, an open factory for the quantum supply chain
The round will also finance KiloFab, which QuantWare presents as the largest factory dedicated to open-architecture quantum processors. The facility would increase the company’s production capacity by a factor of 20 and aims to meet a growing global demand. So far, QuantWare claims to have delivered quantum processors to over 50 clients in 20 countries, including quantum computing companies, national research institutes, and major technology groups.
This point is crucial because quantum computing needs more than just lab breakthroughs. It requires a supply chain. Just as the classical semiconductor industry relies on foundries, packaging, design tools, materials, and specialized suppliers, the quantum industry will need to develop its own industrial layers. QuantWare aims to be positioned exactly there: not as the sole builder of complete quantum computers, but as a horizontal provider of QPUs, manufacturing services, and chiplet packaging for other players.
The comparison to conventional semiconductors is not perfect but helpful. Today, no one expects each chip designer to manufacture their own wafers, build their tools, and control the entire process end-to-end. In quantum, many companies are still trying to solve too many pieces simultaneously. An open architecture and dedicated factory could accelerate the development of systems that do not want or cannot build their processors from scratch.
The involvement of In-Q-Tel also introduces a geopolitical perspective. IQT, a non-profit strategic investor linked to the U.S. national security community and allies, indicates that quantum computing is already considered a strategic technology with implications for defense, cybersecurity, simulation, materials, communications, and industrial competitiveness.
Europe seeks to strengthen its position in a race dominated by giants
QuantWare is based in Delft, Netherlands, and its growth comes at a time when Europe is trying to reinforce its role in deep technologies. Quantum computing is one of the areas where the continent has top-tier research, solid institutes, and promising startups, but also an unresolved question: how to turn this scientific foundation into industrial companies capable of competing with the U.S. and China.
The $178 million round does not close this gap but it does reduce it. The funding allows QuantWare to invest in manufacturing, hire talent, expand capacity, and respond to global clients. It also sends a signal to the market: Europe can produce quantum companies with infrastructure ambition, not just labs or niche projects.
For Intel Capital, in turn, this highlights exposure to a critical component of superconducting quantum computing without having to solve all scaling challenges internally. Intel has been investing in the future of computing for decades, and quantum fits into this long-term vision. The investment in QuantWare also makes sense from the perspective of advanced packaging and manufacturing areas where Intel has been trying to regain prominence in traditional semiconductors.
It’s important to remain cautious. Talking about 10,000 qubit processors does not mean that useful, fault-tolerant quantum computing is already ready to replace classical loads. Qubit quality, error correction, software, algorithms, cryogenics, and system integration remain enormous challenges. Additionally, not all qubits are equal, and raw numbers alone do not guarantee practical advantage.
However, the announcement indicates a new phase. The question is no longer only whether qubits can operate in a lab. It is whether they can be manufactured, connected, and deployed with an industrial logic. In this domain, QuantWare aims to serve as a structural supplier for the entire ecosystem.
Quantum computing will continue to progress cautiously, with timelines that are hard to predict. Nonetheless, QuantWare’s round shows that capital is starting to flow towards foundational components of a future industry: scalable architectures, dedicated factories, and open supply chains. If VIO and KiloFab deliver on their promises, the Dutch company could become a key player in moving superconducting quantum computing from prototypes toward commercial-scale systems.
