QuantWare, a Delft, Netherlands-based quantum processor company, has raised $178 million in Series B funding led by Intel Capital, In-Q-Tel, and ETF Partners. The company designs, fabricates, and integrates scalable superconducting quantum processors using its proprietary VIO™ 3D scaling architecture. The capital will fund industrial-scale production, including the KiloFab facility opening in 2026 with 20x capacity.
Kiloqubit Funding Heats European Quantum
The raise follows IQM's $57 million from BlackRock funds in March 2026 ahead of a US IPO. QuantWare's round marks the largest private funding for a dedicated quantum processor company. This timing aligns with quantum computing funding exploding 374% year-over-year to $4.53 billion in 2025. QuantWare's focus on modular VIO processors positions it to supply the ecosystem amid scaling demands.
Wiring Limits Cap Qubit Counts
Current quantum processors hit a 100-qubit ceiling due to I/O routing bottlenecks in monolithic designs. Superconducting QPUs require thousands of control lines per qubit, straining cryostat space and wiring complexity. This limits progress toward utility-scale systems needed for error-corrected computing. QuantWare targets this pain with vertical integration solutions.
VIO 3D Enables Hyperscale Processors
QuantWare's VIO™ architecture routes 40,000 signal lines in a 15x15cm module, enabling 10,000-qubit processors in a single cryostat. It supports A-Line processors optimized for surface code error correction and D-Line for NISQ applications. The company offers foundry and packaging services, acting as a supplier to 50+ customers across 20 countries. This open architecture fosters interoperability, as seen in deployments with Qblox and Elevate Quantum.
As CEO Matt Rijlaarsdam noted:
"QuantWare’s VIO finally removes the QPU scaling barrier, paving the way for economically relevant quantum computers."
Strategic Investors Back Industrial Push
Intel Capital brings semiconductor expertise, while In-Q-Tel signals national security priorities. Existing backers joined the round, validating QuantWare's trajectory as the world's largest commercial QPU supplier by volume. The funding powers breakthroughs like VIO-40K™, announced in early 2026. This mix of corporate and mission-driven capital underscores conviction in hardware scaling.
Quantum Market Scales to Billions
The quantum computing market stands at $2.04 billion in 2026, projected to reach $18.33 billion by 2034 at a 31.6% CAGR. Competitors include IQM with $320 million+ in Series B funding and Oxford Quantum Circuits at $158 million Series B. Rigetti Computing raised $200 million+ via SPAC, while SEEQC secured $60 million+. Trends toward modular scaling and hybrid systems drive capital into suppliers like QuantWare.
QuTech Spinout Powers Leadership
Co-founded in 2021 by CEO Matt Rijlaarsdam and CTO Alessandro Bruno from QuTech at TU Delft, QuantWare benefits from the Netherlands quantum hub. Scientific advisors include Rami Barends from Google Quantum AI and Charles M. Marcus. Recent additions: CFO Jean-Pierre Pennacino from Motorola/ST Micro and board member Aparna Prabhakar, ex-IBM Quantum VP. This expertise accelerates VIO development and ecosystem partnerships.
KiloFab Launches Production Ramp
QuantWare plans KiloFab opening in 2026 for 20x production capacity and first VIO-40K shipments in 2028. NVIDIA NVQLink integration enables hybrid quantum-classical HPC. The company eyes expansions in hiring quantum engineers and scaling deployments to national labs like ETRI and UniNa.
