QuiX Quantum will lead a Dutch consortium developing technology intended to support a universal photonic quantum computer with more than 100 qubits. The PhotonDelta National Growth Fund-backed mission runs from January 2026 through December 2028 and covers 12 deliverables; the source does not report that a 100-qubit machine has been built or that the project has reached its technical targets.
QuiX Quantum will lead a Dutch national mission to develop technology for a universal photonic quantum computer with more than 100 qubits, under Phase II of the PhotonDelta National Growth Fund programme. The project runs from January 2026 to December 2028 and brings together nine Dutch industrial and academic partners to work on 12 components of the system, according to The Quantum Insider’s November 10 report and the company announcement.
The work spans the photonic computing stack, including low-loss chips, photon sources, detectors, control electronics, packaging and manufacturing. QuiX Quantum is to lead system-level integration and track progress against shared performance indicators and a technology-readiness framework. The stated aim is to develop and integrate components that can support the company’s longer-term fault-tolerant computing roadmap—not to deliver a completed 100-plus-qubit computer by the end of this project.
Among the consortium’s technical targets, imec is working on silicon nitride waveguides and high-speed modulators, while PHIX and MicroAlign are assigned fibre-to-chip coupling with a target of 0.1 decibels per facet. The University of Twente is developing a quasi-deterministic single-photon source. Eindhoven University of Technology is working on photon distillation and resource-state generation, integrated detector arrays, and chip design and tuning methods. Leiden University’s work includes on-chip photon-number-resolving detectors.
Bruco-IC is targeting flip-chip control application-specific integrated circuits with latency below 10 nanoseconds. The source compares that goal with 150 nanoseconds for current feed-forward control. These figures are project targets and a stated comparison, not reported results from completed components. The mission is also expected to conclude with a manufacturing strategy for systems above 100 qubits.
Building the Photonic Supply Chain
The project addresses several linked engineering constraints that can limit the scale-up of photonic quantum systems. Optical loss, photon quality, detection, control speed and manufacturing yield all affect whether separate components can operate together in a larger system. Coordinating work across those areas may help QuiX Quantum test and integrate technologies that would be difficult for one company to develop alone.
The consortium also brings research institutions and industrial suppliers together in the Netherlands, spanning fabrication, packaging, testing and system integration. The programme’s stated goal is to strengthen a domestic and European supply chain for integrated photonics. That could retain more expertise and production capability in the region, though the announcement does not quantify expected economic returns or establish that the project will secure European supply independence.
For readers tracking quantum-computing progress, the distinction between component development and a functioning large-scale computer matters. The mission is a funded development programme with technical targets. Its announcement is not evidence that the targeted qubit count, fault tolerance or commercial performance has already been achieved.

From Universal Hardware to Fault Tolerance
QuiX Quantum is a Dutch-German developer of universal photonic quantum computers. The company says it delivered earlier in 2026 a universal photonic quantum-computing hardware platform developed for the German Aerospace Center’s Quantum Computing Initiative. The new mission builds on that work, while directing attention to components needed for larger systems.
QuiX Quantum’s stated roadmap places demonstrations of loss-tolerant logical-qubit capabilities in 2028–2030, with commercially deployable fault-tolerant photonic computers envisaged beyond 2030. These are roadmap plans, not confirmed delivery dates or demonstrated outcomes. The new mission’s end date, December 2028, overlaps with the beginning of that planned logical-qubit demonstration period.
The initiative is part of Phase II of the PhotonDelta National Growth Fund Integrated Photonics Programme. The supplied announcement describes QuiX Quantum as mission lead and says nine Dutch partners are participating. It lists partner organisations across the work areas, but does not provide a complete, consolidated roster in the material available.
““Scalable, Fault-Tolerant Quantum Computing cannot be built by one company alone.””
— Stefan Hengesbach, CEO of QuiX Quantum
Targets Still Need Demonstration
The announcement describes intended development work and performance targets, but does not report completed results for the 12 deliverables. It is not clear from the supplied material how much funding the mission received, how budgets are allocated among partners, or what specific milestones will be published before the programme ends.
The source also does not define how the project will count “more than 100 qubits” or specify a complete system-level performance benchmark. The stated schedule for logical-qubit demonstrations and commercial fault-tolerant machines remains a company roadmap. Whether the components meet their targets, integrate reliably and can be manufactured at useful scale remains to be established.
Work Continues Through 2028
The partners are scheduled to carry out the mission from January 2026 through December 2028, developing and integrating the 12 planned deliverables. QuiX Quantum says it will coordinate system-level integration and assess progress through shared performance indicators and a technology-readiness framework. The project is expected to finish with a manufacturing strategy for 100-plus-qubit systems.
Further progress reports would be needed to show which components meet their targets and how they perform together. The company’s next stated roadmap milestone is to pursue loss-tolerant logical-qubit demonstrations during 2028–2030; the announcement does not give a specific demonstration date or guarantee that milestone.
Key Questions
What has QuiX Quantum announced?
QuiX Quantum will lead a funded Dutch mission to develop technology foundations for a universal photonic quantum computer with more than 100 qubits. The programme includes nine partners and 12 planned deliverables.
Has a 100-plus-qubit computer been built?
No such result is reported in the announcement. The project is aimed at developing and integrating technologies that could support a system at that scale; its scheduled work runs through December 2028.
What technologies will the partners develop?
The work includes low-loss photonic chips, photon sources, detectors, faster control electronics, packaging and manufacturing methods. The partners also have specific targets for fibre-to-chip coupling and control latency.
When could fault-tolerant capabilities be demonstrated?
QuiX Quantum’s stated roadmap plans demonstrations of loss-tolerant logical-qubit capabilities during 2028–2030. That is a company plan, not a confirmed result or guaranteed deadline.
