Dutch startup’s VIO-40K chip pushes quantum hardware 100× beyond today’s standard and points toward million-qubit machines.
Delft-based hardware company QuantWare has announced what may be the most aggressive scaling move in commercial quantum computing so far: the VIO-40K processor, a chip featuring 10,000 physical qubits, roughly 100 times more than typical state-of-the-art systems in operation today.
The processor is built around a modular 3D architecture that connects multiple “chiplets” with high-fidelity links, supporting around 40,000 I/O lines. This design is meant to preserve signal quality while dramatically expanding the size of the quantum register, avoiding some of the wiring nightmares that plague monolithic chips.
QuantWare positions VIO-40K as a quantum open-architecture device, integrating directly with NVIDIA’s CUDA-Q software stack and NVQLink interconnects. That means the processor is intended to plug into hybrid supercomputing environments where CPUs, GPUs, and QPUs cooperate on large workloads such as chemistry, materials design, and energy optimization.
To support production, the company is building Kilofab, billed as one of the first dedicated large-scale fabs for quantum processors. Located in Delft and expected to open in 2026, Kilofab aims for a 20Ă— increase in production capacity, enabling multiple VIO-40K units to be manufactured for data-center-scale deployments.
Initial shipments of the 10,000-qubit processor are targeted around 2028, with an estimated per-chip cost of about €50 million, placing it firmly in the national-lab / hyperscaler budget range.
Conclusions
QuantWare’s announcement doesn’t solve quantum error correction overnight, but it obliterates the qubit-count ceiling most commercial systems operate under. If the company can deliver stable operation at this scale, VIO-40K plus Kilofab could make the Netherlands a strategic manufacturing hub for quantum supercomputers and accelerate the path toward million-qubit architectures.
