French silicon-quantum startup Quobly on September 2 signed dual cooperation agreements with the Netherlands' TNO and Delft-based Orange Quantum Systems, betting that industrialising silicon spin qubits will require a proper Dutch-French supply chain rather than another lab-scale demo.
TNO takes on device physics
The Quobly–TNO agreement upgrades a January 2026 research partnership into a strategic cooperation focused on the industrialisation of silicon-based quantum computing. TNO's Delft researchers will pair their materials analysis, device characterisation and cryogenic systems engineering with Quobly's 300 mm FD-SOI qubit platform, targeting the yield and uniformity problems that keep spin qubits stuck at single-device demonstrations.
OrangeQS turns test-and-measure toward silicon
The second deal adapts Orange Quantum Systems' modular OrangeQS MAX test platform — originally built for superconducting qubits — to semiconductor spin qubits, adding automated measurement protocols and high-throughput screening for large arrays of silicon quantum dots at cryogenic temperatures. The goal is to establish the yield-screening equivalent of what silicon fabs already run on every wafer of classical CMOS.
Alloy in the cloud by late 2026
Led by CEO Maud Vinet, Quobly's roadmap targets initial cloud-based HPC deployment of its Alloy product family by late 2026, scaling toward one million physical qubits by 2032. The Dutch partnerships follow the company's €115M Series A led by Bpifrance and STMicroelectronics in June, and slot into a European push — alongside Pasqal's protein-gelation work with True Nexus — to prove commercial payoff before US and Chinese platforms lock in their preferred qubit modalities.
Why silicon spin qubits, why now
Silicon spin qubits are attractive precisely because they piggyback on the same manufacturing base that already makes billions of transistors: FD-SOI wafers, EUV lithography, existing packaging. The bottleneck is qualification — knowing which dots on a wafer will behave as usable qubits at millikelvin temperatures. By combining Quobly's device design, TNO's characterisation and OrangeQS's automated test infrastructure, the trio is trying to compress that qualification loop from bespoke experimentation to something more like semiconductor manufacturing.
