QuiX Quantum will lead a PhotonDelta National Growth Fund project running from January 2026 to December 2028, bringing together the company and nine Dutch industrial and academic partners. The consortium plans to develop 12 components across the photonic quantum computing stack for a system designed to exceed 100 qubits; the announcement sets out targets and a development roadmap, not a completed computer.
QuiX Quantum will lead a three-year Dutch national mission to develop technology foundations for a universal photonic quantum computer with more than 100 qubits, under Phase II of the PhotonDelta National Growth Fund programme. The project, scheduled to run from January 2026 to December 2028, brings together QuiX Quantum and nine Dutch industrial and academic partners to develop 12 components across the computing stack. The announcement describes a development effort and targets, not delivery of a completed 100-plus-qubit machine.
The consortium’s work spans low-loss photonic chips, photon sources, detectors, control electronics, packaging and manufacturing. QuiX Quantum will lead system-level integration and track progress against shared performance indicators and a technology-readiness framework. The project is also expected to produce a manufacturing strategy for systems with more than 100 qubits.
The listed technical targets include fibre-to-chip coupling of 0.1 decibels per facet, developed with PHIX and MicroAlign, and control-electronics latency below 10 nanoseconds, a target associated with Bruco-IC. The announcement compares the latter with 150 nanoseconds for current feed-forward control. Other work includes low-loss silicon nitride waveguides and high-speed modulators with imec, a quasi-deterministic single-photon source at the University of Twente, and photon-number-resolving detectors at Leiden University.
Eindhoven University of Technology is listed for work on photon distillation and resource-state generation, integrated single-photon avalanche diode arrays, and design and tuning methods intended to improve chip tolerances and manufacturing yield. These are planned research and engineering tasks; the announcement does not report that the targets have been achieved.
Building the Components for Scale
The project addresses several interdependent engineering challenges that can limit the scale and reliability of photonic quantum computers. Optical loss, photon quality, detection, control speed and chip manufacturability all affect whether components can work together in a larger system. Coordinating work across those areas may help QuiX Quantum test and integrate technologies that would be difficult for a single company to develop alone.
The mission also has an industrial dimension. By linking research institutions with companies involved in fabrication, packaging, electronics and system integration, the consortium aims to strengthen Dutch and European capabilities in the quantum photonics supply chain. That goal is relevant to efforts to retain technical expertise and manufacturing value in Europe. The announcement does not quantify expected economic effects or establish how much of the supply chain will ultimately be based in the region.
For readers following quantum computing, the distinction between component development and a functioning large-scale computer matters. A 100-plus-qubit target indicates the intended scale of the work, but qubit count alone does not show whether a machine can run useful computations or correct errors. The project’s longer-term significance will depend on whether its components meet their targets and can be integrated into a fault-tolerant architecture.

QuiX Quantum’s Fault-Tolerance Roadmap
QuiX Quantum is a Dutch-German developer of universal photonic quantum computers. The company says it delivered hardware for a platform developed for the German Aerospace Center’s Quantum Computing Initiative earlier in 2026. The new mission is presented as a step toward its next-generation fault-tolerant architecture, rather than as a report that the architecture is already complete.
According to the company’s roadmap in the announcement, it plans to develop and demonstrate loss-tolerant logical-qubit capabilities during 2028–2030, with commercially deployable fault-tolerant photonic systems targeted for after 2030. The PhotonDelta-funded mission ends in December 2028, so its work is intended to feed into that next stage. These dates are company plans, not independently verified delivery commitments.
“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 identify a single finished computer as an output due in December 2028. It describes 12 technology deliverables and a manufacturing strategy intended to support a system exceeding 100 qubits. Whether all components will meet their targets, and how they will perform together, remains unknown.
The source also does not provide the full set of performance measures, budget figures, or detailed milestones for each partner. It does not specify the proposed machine’s eventual error rates, application performance, or cost. The stated 2028–2030 logical-qubit demonstration window and post-2030 commercial goal are roadmap plans attributed to QuiX Quantum, not confirmed outcomes.
Work Runs Through December 2028
The mission is scheduled to run from January 2026 through December 2028, with the partners developing their assigned technologies and QuiX Quantum coordinating system-level integration. The consortium says it will monitor progress using shared performance indicators and technology-readiness measures, then conclude with a manufacturing strategy for 100-plus-qubit systems.
Further progress reports will be needed to show which targets have been reached and whether the components can be combined into a working system. QuiX Quantum’s stated next roadmap milestone is work toward loss-tolerant logical-qubit demonstrations during 2028–2030; the company has not provided a more detailed public schedule in the source announcement.
Key Questions
What is QuiX Quantum’s new project?
It is a PhotonDelta National Growth Fund-backed mission led by QuiX Quantum to develop 12 technologies intended to support a universal photonic quantum computer with more than 100 qubits.
Who is participating?
The mission includes QuiX Quantum and nine Dutch industrial and academic partners. The announcement names imec, PHIX, MicroAlign, the University of Twente, Eindhoven University of Technology, Leiden University and Bruco-IC among the participants.
Will the project deliver a 100-plus-qubit computer by 2028?
The source describes development of technology foundations and a manufacturing strategy, not a firm commitment to deliver a completed computer by December 2028. The 100-plus-qubit figure is the system goal the work is intended to support.
What technical targets were announced?
Among the targets are fibre-to-chip coupling of 0.1 decibels per facet and control-electronics latency below 10 nanoseconds. The announcement also describes planned work on photon sources, detectors, low-loss chips and manufacturing yield; these remain development goals.
What happens after the mission ends?
QuiX Quantum says the work is intended to support its plans for loss-tolerant logical-qubit demonstrations in 2028–2030 and commercial fault-tolerant photonic systems after 2030. Those are company roadmap targets, not confirmed results.
