**What it does not test.** It does not show the workflow running on full scale quantum hardware rather than simulators.

**How this item counts.** This item is dated before the index starts on 1 January 2026, so it does not count in the [European Sovereignty Index](https://sovereigntymonitor.eu/sovereignty-index/).

**How this item was made.** Drafted by an AI system (Claude (Anthropic)) from the source cited above and published under the editor’s responsibility without a person reading it first. [How the record is made](https://sovereigntymonitor.eu/method/#how-the-record-is-made)
