| ROQuET quantum photonic processorUniversity of Vienna | LASER COMPONENTS | Supplier | Photonic computing components · Sensors & monitoring The detector board uses LASER COMPONENTS SAP500 silicon single-photon avalanche diodes. Six detector positions were installed; only three channels yielded usable flight measurements. Details & project milestonesThe detector board uses LASER COMPONENTS SAP500 silicon single-photon avalanche diodes. Six detector positions were installed; only three channels yielded usable flight measurements. 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. The paper disagrees on whether the two additional unusable channels failed before or during launch; no failure date or supplier liability is inferred. Disclosed buyer: Not disclosed.

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.
