KPI Comp 2a: European technical leadership: circuit size
KPI observatory / Quantum Computing
Largest quantum computing capacity of an EU computing system on a European or widely adopted global benchmark: the largest random N-qubit Clifford unitary that can be run reliably.
Official values: survey results of the Quantum Flagship Strategic Advisory Board, as published. Trajectory and live measure: calculations of this portal, not the assessment of the SAB.

Remarks and method
- Booklet note f (page 11; scorecard note d): a benchmarking method for these indicators was proposed in 2024 and their values were not ready when the booklet was published.
- These indicators were recently defined; the 2030 target is under review (booklet notes, page 20).
Method as stated: Published benchmarks named in the booklet (reference Computing 2).
Trajectory (calculated by the portal)
qubits
Not assessed
Not assessed: The 2030 target is not set or under review.
The booklet rates each indicator on its own four-level scale (ahead of schedule, on schedule, needs progress, behind schedule); that assessment is not reproduced here.

Live measure of the portal
No automatic measure. Benchmark results (circuit size) are not held by the portal.
