| ROQuET quantum photonic processorUniversity of Vienna | Integrated Optics | Supplier | Photonic computing components ROQuET’s photon-pair source uses a commercial 405 nm fibre-coupled continuous-wave pump-laser module explicitly identified as Integrated Optics hardware. Details & project milestonesROQuET’s photon-pair source uses a commercial 405 nm fibre-coupled continuous-wave pump-laser module explicitly identified as Integrated Optics hardware. This records an explicitly identified, implemented role in the flown research payload; it is not evidence of a separately announced paid contract. The direct legal buyer, contract execution/selection date, price and procurement terms are not disclosed. September 21, 2026 is the paper submission date, not the procurement date. Additional evidence for this same role: https://integratedoptics.com/blog/news/io-laser-enters-the-era-of-quantum-space-research. The July 14, 2025 supplier release describes the same University of Vienna 405 nm MATCHBOX laser launched June 23, 2025. The research paper explicitly names Integrated Optics and the Matchbox module. July 14 is the earliest retained supplier disclosure, not a procurement date. Disclosed buyer: Not disclosed. Associated organization: University of Vienna. ROQuET quantum photonic processor: In-orbit operation demonstrated Next project milestone: No next mission milestone disclosed in the September 2026 paper. This is a project target, not a supplier delivery commitment. Evidence checked 27 Oct 2026. | Role confirmedSource ↗ |

Technical specifications retain the source’s original units and evidence status. Hardware counts, compute rates and power are not equivalent; launched hardware does not establish demonstrated performance. Supplier counts include suppliers and hosts only, reflect current filters and cover this directory, not the entire market. “No record” means no disclosure captured; it does not mean the work is unawarded. Latest developments use source dates, not routine review or collection dates.
