QuiX Quantum will lead a Dutch consortium funded through Phase II of the PhotonDelta National Growth Fund programme to develop technology for a universal photonic quantum computer with more than 100 qubits. The project runs from January 2026 to December 2028 and covers 12 components, but the announcement describes development goals, not a completed 100-qubit system.
QuiX Quantum will lead a Dutch consortium developing technology for a universal photonic quantum computer with more than 100 qubits, under Phase II of the PhotonDelta National Growth Fund programme. The mission runs from January 2026 through December 2028 and will bring together the company and nine industrial and academic partners to develop and integrate 12 components across the photonic computing stack.
The project, titled “Delivery of a 100+ Qubit Universal Quantum Computer,” targets technical needs including lower optical loss, improved photon sources, advanced detectors, faster control electronics and chips that are easier to manufacture. QuiX Quantum is responsible for leading the mission and integrating partner results at system level, using shared performance indicators and a technology-readiness framework, according to the project announcement.
Partners are assigned work across the system. The source names imec for low-loss silicon nitride waveguides and high-speed modulators; PHIX and MicroAlign for fibre-to-chip coupling; the University of Twente for a quasi-deterministic single-photon source; and Eindhoven University of Technology for photon distillation, detector arrays and chip-design and tuning work. Leiden University is developing on-chip photon-number-resolving detectors, while Bruco-IC is working on flip-chip control ASICs.
The announcement gives several targets rather than reporting completed results. These include fibre-to-chip coupling of 0.1 decibels per facet and control latencies below 10 nanoseconds, compared with 150 nanoseconds for current feed-forward control as described by the source. The project is also expected to produce a manufacturing strategy for systems above 100 qubits. Those targets remain development objectives; the announcement does not say the components or full computer have already been demonstrated.
Building the Photonic Supply Chain
The mission addresses a practical obstacle to scaling photonic quantum computers: performance depends on multiple connected components, not just the processor chip. Optical loss, photon quality, detection and control speed can each constrain how a system operates as it grows. Coordinated work across these areas could help QuiX Quantum test whether the necessary technologies can be integrated into a larger system.
The programme also has an industrial and regional dimension. Its partners span research, chip manufacturing, packaging, electronics and system integration in the Netherlands. PhotonDelta’s National Growth Fund programme is intended to support integrated-photonics development and industrialisation. The mission’s proposed manufacturing strategy could inform later production work, but the announcement does not establish that a commercial-scale system or market deployment will result by 2028.

QuiX Quantum’s Fault-Tolerant Roadmap
QuiX Quantum describes the mission as part of a longer route from universal photonic quantum computing toward fault-tolerant systems. The company says it delivered a universal photonic quantum computing hardware platform earlier in 2026 for the German Aerospace Center’s Quantum Computing Initiative. That is a company-reported prior development, and the supplied material does not provide independent technical results for the platform.
The company’s stated roadmap calls for development and demonstration of loss-tolerant logical-qubit capabilities during 2028–2030, with commercially deployable fault-tolerant photonic computers envisaged beyond 2030. The current mission is intended to develop enabling technologies and manufacturing methods; it is not itself a report that fault-tolerant computing has been achieved.
““Scalable, Fault-Tolerant Quantum Computing cannot be built by one company alone.””
— Stefan Hengesbach, CEO of QuiX Quantum
Targets Still Need Demonstration
The announcement does not disclose the grant’s monetary value, the full list of all nine partner organisations, or detailed milestones for each of the 12 deliverables. It also does not provide independent evidence that the stated component targets have been met. The 100-plus-qubit computer is the mission’s development goal, not a confirmed completed system.
It remains unclear how the partners will measure system-level progress, what performance the integrated system is expected to reach, and whether all components will meet their stated targets by December 2028. The source also does not specify what funding or follow-on arrangements would support manufacturing after the project ends.
Work Through December 2028
The consortium’s stated next step is to carry out its component-development and integration work during the project period, ending in December 2028. QuiX Quantum says it will track progress against shared key performance indicators and technology-readiness measures, then conclude the mission with a manufacturing strategy for systems above 100 qubits.
Further evidence will come from disclosed milestones and demonstrations, particularly whether the partners achieve the optical-loss, photon-source, detector and control targets and integrate them into a working system. QuiX Quantum’s broader roadmap points to logical-qubit demonstrations in 2028–2030, but the announcement does not provide specific dates or a schedule for those demonstrations.
Key Questions
What is the QuiX Quantum mission?
It is a PhotonDelta National Growth Fund-supported project led by QuiX Quantum to develop and integrate technologies intended for a universal photonic quantum computer with more than 100 qubits.
When does the project run?
The announced project period is January 2026 through December 2028.
Has a 100-plus-qubit computer already been built?
The announcement does not say that one has been built. It describes a development mission and its targets, including a planned manufacturing strategy for systems above 100 qubits.
What technologies will the partners work on?
The work covers low-loss photonic chips, photon sources, detectors, control electronics, packaging and manufacturability, among other components across the photonic quantum computing stack.
What comes after this mission?
QuiX Quantum says its broader roadmap includes work toward loss-tolerant logical-qubit demonstrations in 2028–2030. The company’s stated longer-term aim is commercially deployable fault-tolerant photonic quantum computers beyond 2030; those are roadmap goals, not results established by this announcement.
