QuiX Quantum Leads National Mission to Develop 100+ Qubit Photonic Quantum Computer

QuiX Quantum heads a national mission to build a 100+ qubit photonic quantum computer

QuiX Quantum, a Dutch‑German photonic‑quantum startup, has been awarded Phase II funding from the PhotonDelta National Growth Fund (NGF) to coordinate a two‑year, multi‑partner programme. The mission, running from January 2026 to December 2028, brings together nine Dutch industrial and academic partners to develop twelve key components across the photonic quantum‑computing stack – from ultra‑low‑loss waveguides and deterministic photon sources to on‑chip detectors, high‑speed control ASICs and manufacturable chip designs.

Scope of the mission

• Lower optical loss: silicon‑nitride waveguides and high‑speed modulators targeting 0.1 dB per facet coupling.
• Better photons: quasi‑deterministic single‑photon sources and photon‑distillation techniques to stay below error thresholds.
• Improved detection: on‑chip photon‑number‑resolving detectors and integrated SPAD arrays.
• Faster control: flip‑chip ASICs aiming for sub‑10 ns latency, a significant improvement over today’s ~150 ns feed‑forward loops.
• Manufacturability: inverse‑design methods and post‑fabrication tuning to boost yield and tolerance.

The consortium will integrate these advances into a system‑level prototype and deliver a manufacturing strategy for scaling beyond 100 qubits, laying groundwork for fault‑tolerant photonic quantum computers after 2030.

Why the initiative matters

Photonic platforms promise room‑temperature operation and low decoherence, but scaling to useful sizes has been hampered by loss, photon‑generation efficiency, detection speed and packaging complexity. By tackling all of these challenges in parallel, the mission aims to create a coherent technology foundation that can be industrialised within Europe, strengthening the regional quantum‑photonic supply chain.

Outlook and next steps

QuiX Quantum’s roadmap already includes a universal photonic hardware platform delivered to the German Aerospace Center earlier in 2026. The current mission will extend that work toward logical‑qubit demonstrations slated for 2028‑2030. Success will depend on meeting the technical KPIs set for each deliverable and on the consortium’s ability to translate laboratory‑scale components into manufacturable modules.

The project is funded by the PhotonDelta National Growth Fund programme (www.photondelta.com).
