Summary
Dutch startup QuantWare unveiled VIO-40K, a 3D packaging architecture to build superconducting processors with up to 10,000 qubits on a single device, roughly 100x today’s largest chips. The design stacks chiplets and interposers and routes control vertically into qubits, using 40,000 IO lines and high fidelity chip-to-chip links. Going vertical reduces cryogenic wiring density on the surface and mitigates cross-talk, targeting the long-standing IO bottleneck.
For security leaders this is a scaling play that could shift assumption timelines. If QuantWare’s integrated approach delivers more compute per dollar and per watt than networking many smaller processors, practical quantum performance could advance faster than expected in superconducting platforms. The risk remains tied to error rates and error correction overhead, not just qubit count, but a viable KiloQubit-class unit would tighten planning windows for PQC deployment.
QuantWare also announced KiloFab, an industrial quantum chip fab in Delft planned for 2026, aligned with its open Quantum Open Architecture standard. The company targets a 20x production boost and first VIO-40K shipments by 2028. For the quantum security community this signals maturing supply chains and standardization in Europe, a catalyst to accelerate migration plans, crypto agility, and data inventory efforts.
