QuantWare, the Delft-based developer of superconducting quantum processing units (QPUs), has announced a $178 million (€152 million) Series B funding round. The investment, which represents the largest private round ever raised by a dedicated industrial quantum processor company, is intended to accelerate the production of the company’s “VIO” modular architecture and the construction of “KiloFab,” a high-volume production facility. The round saw participation from major strategic and venture players, including Intel Capital, In-Q-Tel (IQT), and ETF Partners, alongside existing backers such as FORWARD.one and the Invest-NL Deep Tech Fund.
The centerpiece of the announcement is the VIO-40K™, an architecture designed to support up to 10,000 qubits. This represents a 100x increase over the current commercial state-of-the-art. Unlike monolithic chip designs that face diminishing yields as they grow, QuantWare’s VIO technology utilizes a modular, open-architecture approach. By focusing on “chiplet” packaging and advanced 3D integration, QuantWare aims to solve the routing and interconnect challenges that have historically plagued superconducting circuits. This modularity allows the company to integrate third-party qubit designs onto their proprietary backplane.
To support the rollout of VIO, QuantWare is investing heavily in KiloFab, which it describes as the world’s largest dedicated quantum open architecture fab. The facility is expected to increase the company’s production capacity by 20x. The move toward dedicated industrial-scale fabrication is a significant shift for the industry. While many quantum hardware players rely on shared university cleanrooms or general-purpose foundries, QuantWare’s dedicated facility suggests a transition toward “hyperscale” quantum manufacturing.
QuantWare reports it has shipped QPUs to more than 50 customers across 20 countries, including national labs and global conglomerates. By securing investment from Intel Capital and IQT, QuantWare has gained powerful allies that bridge the gap between commercial venture capital and strategic national interests. QuantWare’s strategy is distinct from “full-stack” companies like IBM or Google. By providing the underlying processor architecture and foundry services to other quantum computer builders, QuantWare is betting that the industry will eventually move toward a horizontally integrated supply chain.
