QuantWare
Overview
World's first commercial off-the-shelf superconducting quantum processors. Proprietary VIO 3D vertical interconnect technology enables scaling to 10,000+ qubits. Sells QPUs at roughly one-tenth the cost of competitors.

Technology Approach
QuantWare is positioning itself as the “Intel of quantum computing” — selling quantum processor chips to anyone building a quantum computer, rather than building complete systems.
Their key innovation is VIO (Vertical Interconnect Overlay) — a 3D fabrication technology that routes qubit connections vertically rather than to chip edges. This removes the primary bottleneck preventing superconducting processors from scaling beyond current qubit counts, potentially enabling processors with 10,000+ qubits.
Business Model
Most quantum hardware companies build entire systems (chip + cryogenics + control electronics + software). QuantWare just builds the chip and sells it at roughly one-tenth the cost. Partners like Seeqc, Q-CTRL, and Orange Quantum Systems provide the other components.
This component-supplier model mirrors how the classical computing industry evolved: Intel didn’t build computers — it built the processor inside them.
Competitive Position
Strengths: Unique market position (only commercial QPU supplier), 3D interconnect technology for scaling, low cost, strong EU backing.
Challenges: Dependent on partners for full-stack integration. Unproven at scale. Competing indirectly with IBM and Google who build their own chips.
