Verified [European Space Agency press release, 1 September 2026](https://www.esa.int/Applications/Connectivity%5Fand%5FSecure%5FCommunications/Quantum%5Flaser%5Fpulse%5Fgenerator%5Fready%5Fto%5Fpower%5FESA%5Fs%5FQKDSat?ref=sovereigntymonitor.eu)

**What it does not test.** This confirms a component qualification and delivery, not a satellite launch, an operational service date, or the value of the underlying ARTES contract, which ESA's release does not state.

**How this item counts.** No movement: no answer to who owns, who operates, whose law governs or who made the parts changes. Weight 0\. Component delivery within already-European ARTES program; parts answer unchanged, no prior dependency shifted. [European Sovereignty Index](https://sovereigntymonitor.eu/sovereignty-index/)
