QuantWare has closed a $178 million Series B equity round, the largest private fundraise on record for a dedicated quantum processor company. The capital follows the announcement of VIO-40K™, a new quantum processor architecture targeting 10,000 qubits — a hundredfold increase over the current commercial state of the art. Alongside the funding, the company announced KiloFab, a purpose-built quantum fabrication facility that will expand its production capacity by 20x.
The round drew new investors including Intel Capital, IQT, and ETF Partners, with existing backers FORWARD.one, Invest-NL Deep Tech Fund, InnovationQuarter Capital, Ground State Ventures, and Graduate Ventures participating. The round was oversubscribed.
QuantWare occupies an unusual position in the quantum stack. It is the only company currently designing, fabricating, and integrating modular quantum processors at industrial scale on an open architecture. Its VIO™ platform — a modular Quantum Processor Architecture built around chiplet-based design — is structured explicitly to serve third parties. Competitors’ chiplets and designs can be scaled on QuantWare’s architecture, making the company less a rival to quantum software and system builders than an infrastructure layer beneath them. The company has shipped to more than 50 customers across 20 countries and describes itself as the world’s largest commercial QPU supplier by volume.
That open-platform positioning is the strategic bet the VIO-40K announcement is underwriting. Superconducting quantum computing at scale is constrained not by qubit design alone but by routing, packaging, and the difficulty of manufacturing at volume without degrading coherence. Intel Capital’s Kike Miralles, in the company’s announcement, named exactly those constraints as the reason QuantWare’s architecture is credible: the company identified the manufacturing ceiling early and built VIO to address it rather than deferring the problem to a later generation.
KiloFab is the infrastructure answer to that manufacturing constraint. A 20x increase in production capacity is not a marginal expansion — it signals that QuantWare is building toward becoming a foundry-class supplier rather than a research-grade vendor. The customers on its current list span quantum computing companies, national technology institutes, and major global technology conglomerates, a distribution that reflects the early-stage but strategically diverse demand now pulling at quantum hardware.
The 10,000-qubit target in VIO-40K is significant not because fault-tolerant quantum computing at that scale is imminent, but because the architecture for reaching it is now being committed to fabrication capacity. The distance between current commercial processors and 10,000 coherent, controllable qubits remains substantial. What QuantWare is offering the ecosystem is a credible industrial path to that number, built on a platform others can build on rather than a proprietary stack that concentrates the ceiling at one company’s roadmap.
