TL;DR
QuiX Quantum will lead a Dutch consortium developing technology for a universal photonic quantum computer with more than 100 qubits. The PhotonDelta National Growth Fund-backed mission runs from January 2026 to December 2028 and covers 12 components, but the project announcement does not claim that a machine of that scale has been built or demonstrated.
QuiX Quantum will lead a Netherlands-based mission to develop technology for a universal photonic quantum computer with more than 100 qubits, bringing together the company and nine Dutch industrial and academic partners. Funded under Phase II of the PhotonDelta National Growth Fund programme, the project runs from January 2026 to December 2028 and aims to address technical barriers across the photonic computing stack; it is a development programme, not an announcement that a 100-plus-qubit computer is already operational.

The consortium plans to develop and integrate 12 deliverables, spanning low-loss photonic chips, photon sources, detection, control electronics, packaging and manufacturing. QuiX Quantum will coordinate the partners and integrate results at system level, using shared performance indicators and a technology-readiness framework, according to the company’s announcement.
The work targets several engineering constraints at once. The project lists ultra-low-loss silicon nitride waveguides and high-speed modulators; a quasi-deterministic single-photon source; photon distillation and resource-state generation; on-chip photon-number-resolving detectors and integrated SPAD arrays; and more manufacturable chips. Fibre-to-chip coupling is targeted at 0.1 dB per facet, while control ASICs are intended to reach latency below 10 nanoseconds, compared with 150 nanoseconds for current feed-forward control as stated in the release. These are project targets, not reported results.
Partners named in the announcement include imec, PHIX, MicroAlign, the University of Twente, Eindhoven University of Technology, Leiden University and Bruco-IC. The project is also expected to produce a manufacturing strategy for systems above 100 qubits. The source describes a consortium of QuiX Quantum and nine Dutch partners, though the excerpt does not provide a complete list of all nine.
Building the Photonic Supply Chain
The mission matters because scaling a photonic quantum computer depends on more than increasing the number of qubits. Optical loss, the quality and availability of photons, detector performance and the speed of control systems can all constrain a system. The consortium’s approach puts work on these connected components into one programme, with QuiX Quantum responsible for system-level integration.
For the Netherlands and Europe, the effort also aims to develop domestic capabilities across chip fabrication, packaging, testing and integration. PhotonDelta’s National Growth Fund programme is intended to support integrated-photonics applications and industrialisation. The company says strengthening regional suppliers could keep more expertise and economic value within Europe; that is a stated ambition, not a demonstrated outcome of this project.

From Hardware Delivery to Logical Qubits
The mission sits within a longer development path described by QuiX Quantum. The company says it delivered a universal photonic quantum-computing hardware platform earlier in 2026 for the German Aerospace Center’s Quantum Computing Initiative. The new programme is intended to build on that work and support the company’s move toward fault-tolerant architecture.
QuiX Quantum’s stated roadmap calls for development and demonstration of loss-tolerant logical-qubit capabilities during 2028–2030, with commercially deployable fault-tolerant photonic computers described as a goal beyond 2030. Those dates are company plans, not guarantees. The mission’s December 2028 end date overlaps with the beginning of that planned logical-qubit period, making the technologies and manufacturing work relevant to the next stage of development.
““Scalable, Fault-Tolerant Quantum Computing cannot be built by one company alone.””
— Stefan Hengesbach, CEO of QuiX Quantum
Targets Still Need Demonstration
The announcement sets out development goals but does not report achieved performance for the planned components, nor does it provide evidence that a 100-plus-qubit photonic computer has been built. It is not yet clear how the project will measure completion of each deliverable, what level of system integration will be demonstrated by December 2028, or whether all stated targets will be met on schedule.
The release also does not disclose the mission’s total funding amount, the allocation among partners, or a full partner list. Its claims about a stronger European supply chain and future commercial systems remain intended outcomes. The relationship between completion of this mission and the planned 2028–2030 logical-qubit demonstrations is described as supportive, but the announcement gives no guarantee that the demonstrations will follow.
Integration Work Through 2028
The consortium’s stated next step is to begin work across the 12 technology areas and integrate partner results against its shared performance and readiness framework. The mission is scheduled to continue through December 2028, when it is expected to conclude with a manufacturing strategy for systems above 100 qubits.
Readers should look for reported component results, system-level demonstrations and updates to QuiX Quantum’s logical-qubit roadmap as the project proceeds. The announcement does not give dates for intermediate milestones or specify when those results will be published.
Key Questions
Has QuiX Quantum built a 100-plus-qubit photonic computer?
No such completed machine is announced. The mission is intended to develop and integrate technology foundations for a universal photonic quantum computer with more than 100 qubits.
Who is participating in the mission?
QuiX Quantum is leading a consortium described as including 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, but the supplied report does not list every partner.
When does the project run?
The mission is scheduled to run from January 2026 through December 2028, under Phase II of the PhotonDelta National Growth Fund programme.
What technologies will the partners work on?
The programme covers 12 deliverables, including low-loss chips, photon sources, detectors, faster control electronics, packaging and manufacturing methods. The performance figures in the announcement, including the proposed control latency, are targets rather than confirmed results.
What is the project’s connection to fault-tolerant computing?
QuiX Quantum says the mission’s technologies are intended to support its fault-tolerant roadmap. The company plans loss-tolerant logical-qubit development and demonstrations during 2028–2030, but that remains a roadmap target.
