QuiX Quantum leads a Dutch mission to build a 100+ qubit photonic computer

The Netherlands is backing a national effort to build a large photonic quantum computer. The Quantum Insider reports that QuiX Quantum will lead a mission funded by Phase II of the PhotonDelta National Growth Fund photonics programme, running from January 2026 to December 2028

The amount of funding has not been disclosed. Partners include imec for silicon nitride waveguides and modulators, PHIX and MicroAlign for fibre to chip coupling targeting 0.1 dB of loss per facet, and the University of Twente for a single photon source

TU Eindhoven will work on photon distillation and detector arrays, Leiden on photon number resolving detectors, and Bruco IC on control chips targeting under 10 nanoseconds of latency against 150 today. The article gives the number of partners as both seven and nine

QuiX plans loss tolerant logical qubits in 2028 to 2030 and commercial fault tolerant machines after 2030. Chief executive Stefan Hengesbach called the grant a strong vote of confidence in the Dutch photonics ecosystem and said scalable fault tolerant quantum computing cannot be built by one company alone

Bringing together specialists in waveguides, detectors, coupling and control chips shows how many pieces a photonic quantum computer needs. The Netherlands has a strong photonics industry, so this plays to national strengths. Cutting control latency from 150 to under 10 nanoseconds would be a big step on its own

Do you think photonic qubits have an advantage over other approaches? And can smaller countries compete in quantum computing?
