| ROQuET quantum photonic processorUniversity of Vienna | Xiphos Technologies | Supplier | Processors / accelerators · Avionics / integrated electronics The flown payload is controlled by a Xiphos Q7S single-board computer using a Xilinx Zynq-7000 SoC with ARM Cortex-A9 and FPGA logic, running a custom Linux/Yocto and Python environment. Details & project milestonesThe flown payload is controlled by a Xiphos Q7S single-board computer using a Xilinx Zynq-7000 SoC with ARM Cortex-A9 and FPGA logic, running a custom Linux/Yocto and Python environment. 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. 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 Sept 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.
