QuantWare has announced a $4.5 million extension to its Series A round, bringing the total raised to $27 million. The Delft-based quantum hardware company is commercializing VIO, a proprietary scaling technology aimed at enabling superconducting quantum processors with more than one million qubits.
The additional funding will be directed toward expanding QuantWare’s chip fabrication capabilities and growing its team. This aligns with the company’s broader strategy to support large-scale quantum processor development and deliver high-performance quantum hardware to customers globally. The funding round was oversubscribed, reflecting growing investor confidence in QuantWare’s roadmap and its role in the broader quantum ecosystem.
VIO is designed to address scaling bottlenecks in superconducting architectures, providing a path to quantum processors with dramatically higher qubit counts. According to QuantWare, the technology allows exponential improvements in quantum computing performance by facilitating more densely integrated quantum chips without compromising coherence or control.
QuantWare operates under a Quantum Open Architecture model, offering not only full-stack QPUs based on VIO but also foundry and packaging services. The company supplies hardware to clients in over 20 countries, supporting both established vendors and emerging quantum system developers.
