QuiX Quantum will lead a Dutch consortium working to develop the technology foundations for 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 components across the system, but the announcement does not say that a 100-plus-qubit machine will be completed by the project’s end.
QuiX Quantum will lead a Dutch national mission to develop the 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 is scheduled to run from January 2026 through December 2028 and brings together the company and nine Dutch industrial and academic partners to work on 12 parts of the photonic computing stack.
The mission, named “Delivery of a 100+ Qubit Universal Quantum Computer,” is focused on developing and integrating components rather than announcing a completed computer. Its work spans low-loss photonic chips, photon sources, detectors, control electronics, packaging and manufacturing. QuiX Quantum is responsible for bringing partner results together at the system level and tracking progress against shared performance indicators and technology-readiness measures.
The project targets several technical constraints on scaling photonic systems. The source material lists ultra-low-loss silicon nitride waveguides and high-speed modulators from imec, as well as fibre-to-chip coupling with a target loss of 0.1 decibels per facet involving PHIX and MicroAlign. Other planned work includes a quasi-deterministic single-photon source from the University of Twente, photon distillation and resource-state generation at Eindhoven University of Technology, and on-chip photon-number-resolving detectors at Leiden University.
Control and manufacturability are also in scope. Bruco-IC is working on flip-chip control ASICs with a stated latency target below 10 nanoseconds; the project compares that target with 150 nanoseconds for current feed-forward control. Eindhoven University of Technology is also tasked with inverse design and post-fabrication tuning intended to improve chip tolerances and manufacturing yield. These are project targets, not reported results.
Building the Photonic Supply Chain
The project’s significance lies in addressing several dependencies that must work together before a larger photonic quantum computer can be built. Reducing optical loss, producing more useful photons, detecting them and controlling operations quickly are linked engineering challenges. The mission combines those strands in one consortium, with QuiX Quantum coordinating system integration rather than treating each component as a separate research effort.
PhotonDelta says the programme supports the development and industrialisation of integrated photonics. The partners span research, chip fabrication, packaging, electronics and system integration, which could strengthen capabilities in the Netherlands and the wider European supply chain. The announcement presents that local capacity as a way to retain more expertise and economic value in Europe. Those are programme aims; the release does not provide a quantified economic-impact estimate or evidence that supply-chain dependence has already changed.
For quantum computing users, the longer-term importance is the possibility of moving from a universal device toward fault-tolerant systems. But the announced mission is a technology-development programme, not evidence that such a system is already available or that its performance has been demonstrated.

From Hardware Delivery to Logical Qubits
QuiX Quantum describes itself as 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 source material gives no independent performance assessment or further specifications for that 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 envisioned beyond 2030. The mission ending in December 2028 is intended to contribute technologies and a manufacturing strategy for systems above 100 qubits. Its schedule overlaps the planned logical-qubit work, but the announcement does not say that the mission alone will deliver those demonstrations.
““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 planned research, engineering targets and a roadmap; it does not report that the 12 deliverables have been completed or integrated. It also does not disclose the award amount, detailed interim milestones, independent evaluation criteria or how the project will address any targets that are missed. The stated 0.1 dB-per-facet coupling and sub-10-nanosecond control figures are goals, not measured outcomes in this announcement.
It remains unclear what precise performance criteria will define a successful 100-plus-qubit system, whether the project will build and demonstrate such a system by December 2028, and what applications it could support. The release says the mission will conclude with a manufacturing strategy, which is not the same as confirming commercial production or fault-tolerant operation.
Milestones Through December 2028
The consortium’s work is scheduled to continue through December 2028, with QuiX Quantum integrating partner technologies and monitoring progress against the mission’s shared indicators and technology-readiness framework. The stated endpoint includes a manufacturing strategy for systems above 100 qubits, intended to prepare for later industrialisation.
The next meaningful updates would be evidence of component performance, integration milestones and progress toward the company’s planned logical-qubit demonstrations during 2028–2030. The announcement does not provide dates for those interim reports or identify a specific public demonstration schedule.
Key Questions
What has QuiX Quantum been selected to lead?
QuiX Quantum will lead a PhotonDelta National Growth Fund-backed mission to develop technology foundations for a universal photonic quantum computer with more than 100 qubits. The project includes nine Dutch industrial and academic partners.
Will the project deliver a 100-plus-qubit computer by 2028?
The announcement describes a programme to develop and integrate 12 components and produce a manufacturing strategy. It does not confirm that a finished 100-plus-qubit computer will be delivered by the project’s December 2028 end date.
What technologies will the partners work on?
The work covers lower-loss chips and fibre connections, photon sources, photon detection, faster control electronics, packaging and manufacturing methods. Specific stated targets include 0.1 dB of coupling loss per facet and control latency below 10 nanoseconds; these remain targets, not reported results.
How does the mission fit QuiX Quantum’s longer-term plans?
The company says the mission supports its fault-tolerant computing roadmap. Its stated plan is to develop and demonstrate loss-tolerant logical-qubit capabilities in 2028–2030, with commercial fault-tolerant systems envisioned beyond 2030.
