Scaling quantum computers has hit a wall at 100 qubits. A new architecture breaks limits, enabling processors for large-scale quantum computing.
Quantum computing has long been limited by QPU size. For nearly a decade, organizations trying to build large-scale quantum systems have been constrained to processors of around 100 qubits. Even leading companies have struggled to scale: Google’s QPUs grew from 53 to 105 qubits over six years, and IBM’s 120-qubit QPU is expected to lead the market by 2028. Scaling beyond these limits has been difficult due to hardware constraints, forcing teams to link multiple smaller processors, which raises costs and reduces efficiency.
QuantWare’s VIO-40K addresses this challenge. Its new VIO 3D scaling architecture enables QPUs with 10,000 qubits, 100 times larger than most current offerings, while fitting into a smaller package than today’s QPUs. Built entirely from chiplet modules connected via ultra-high-fidelity chip-to-chip links, VIO-40K delivers far more computing power per dollar and per watt than networks of smaller processors. Its 40,000 input-output lines make scaling superconducting qubit designs practical for organizations seeking large, high-performance QPUs.
The VIO ecosystem also solves connectivity challenges. NVIDIA NVQLink, an open platform for building logical QPUs, is integrated into VIO-40K. This allows quantum processors to link seamlessly to classical AI supercomputers with low latency and high throughput, accessible via NVIDIA’s CUDA-Q platform. Combined, they enable the large-scale hybrid quantum-classical computing needed for real-world applications.
To support production and adoption, QuantWare is launching Kilofab, an industrial-scale QPU fabrication facility opening in 2026 at its Delft headquarters. Kilofab will produce VIO-40K processors at scale, increasing capacity 20-fold, and become the world’s first dedicated fab for Quantum Open Architecture devices, as well as one of the largest quantum fabs globally.
“For years, people have heard about quantum computing’s potential to transform fields from chemistry to materials to energy, but the industry has been stuck at 100-qubit QPUs forcing the field to theorize about interesting but far-off technologies,” said Matt Rijlaarsdam, CEO of QuantWare. “QuantWare’s VIO finally removes this scaling barrier, paving the way for economically relevant quantum computers. With VIO-40K, we’re giving the entire ecosystem access to the most powerful, hyper-scaled quantum processor architecture ever.”
