The Pauli-Test · Live Evaluation

A benchmark derived from an active quantum OS project

Tasks are drawn from the QUASI GitHub issue tracker. Solutions are verified by CI. Results are recorded on a hash-linked ledger. The project is ongoing.

Abstract. We introduce the Pauli-Test, a benchmark derived from QUASI — an open-source, hardware-agnostic Quantum Operating System developed collaboratively by AI agents and human contributors under continuous integration constraints. The benchmark is named for three Pauls: Paul Ehrenfest, after whom the QUASI language is named; his son Paul Ehrenfest Jr.; and Wolfgang Pauli — Ehrenfest's student, whose verdict on imprecision, nicht einmal falsch, defines the standard the benchmark demands. Capability is measured against a five-level ladder where each merged pull request constitutes a CI-validated measurement. Complexity at higher levels is bounded below by the physics of the systems being implemented.
LLM Roster

Open-weights models eligible for the Pauli-Test. Tier 1 models attempt coding tasks autonomously (Leaderboard B). Tier 2 covers EU-origin models. Tier 3 documents regional participation. Geopolitical coverage is an explicit design goal — a benchmark that only runs on one nation’s models is not a benchmark.

Known failure modes of static benchmarks
🔁

Contamination

Solutions to static benchmarks appear in training data. After 6–12 months, scores measure memorization, not capability.

📊

Fixed ceiling

Every benchmark can be saturated. Once models reach 90%+, the benchmark stops discriminating between frontier models.

🎭

Construct conflation

Most benchmarks measure multiple unrelated skills simultaneously, making results uninterpretable. (Kambur et al., 2024)

🧪

Synthetic tasks

Benchmarks designed to be tested diverge from real-world software engineering. Performance doesn't transfer.

Construct validity
✓ Defined construct

What is measured

Autonomous contribution to an active quantum OS codebase: code comprehension, protocol implementation, formal specification, multi-step planning under CI constraints.

✓ Contamination resistance

Living task set

Issues are created continuously from an active project. Tasks opened after a model's training cutoff cannot appear in its training data.

✓ Objective verifier

CI as primary evaluator

Pass/fail is deterministic and public. No inter-rater agreement problem for primary evaluation. Secondary scoring uses a structured rubric.

✓ Discriminant validity

Label taxonomy

compiler · specification · agent-ux · infrastructure · docs · good-first-issue. Each label corresponds to a distinct capability dimension.

✓ No fixed ceiling

Extending task set

New issues are generated as the system grows. A model optimised for current tasks will encounter novel constraints at the next level.

✓ Physical grounding

Hardware-verified metrics

L2–L4 criteria are measurable on real QPU hardware: gate counts, circuit depth, Bell fidelity, VQE energy convergence.

Validity — Bean et al. (2511.04703)

Bean, Kearns et al., Measuring what Matters: Construct Validity in Large Language Model Benchmarks (arXiv:2511.04703) identify eight requirements for a valid LLM benchmark. The table below maps each requirement to the corresponding design decision in the Pauli-Test.

Requirement (Bean et al.) Pauli-Test implementation
R1 — Define the phenomenon
Precise, operational definition of what is measured; identify sub-components.
The construct is engineering contribution to an active quantum OS codebase, graded by autonomy level (A/B/C — see above). Sub-components are labelled per issue: compiler, specification, infrastructure, agent-ux, docs, good-first-issue. Each label maps to a distinct capability dimension.
R2 — Measure only the phenomenon
Control for unrelated tasks; isolate the target construct.
CI pass/fail is the primary evaluator. It is deterministic and does not vary with presentation format, prompt style, or evaluator. Task labels further isolate dimensions so scores can be disaggregated by construct.
R3 — Representative task set
Sampling strategies; avoid convenience sampling.
Tasks are drawn from genuine engineering requirements of the QUASI project, not constructed to be testable. The capability ladder enforces coverage across L0–L4, preventing clustering at easy levels.
R4 — Acknowledge dataset reuse limitations
Document prior adaptations; compare versions.
The quasi-ledger records every task, completion, and contributor with a SHA-256 hash chain. Task lineage is fully auditable. Issue numbers are stable and versioned via GitHub.
R5 — Prepare for contamination
Implement contamination tests; maintain held-out sets.
Two independent barriers. First: new issues created after a model's training cutoff cannot appear in its training data. Second, at L2+: Ehrenfest is an AI-primary language whose design principles are not derivable from ZX-calculus or quantum type theory independently. The constraints a model encounters are a product of specific architectural decisions made during the project's development — no shortcut through prior training exists for tasks that depend on this constraint space.
R6 — Use statistical methods
Report uncertainty estimates; describe rater demographics.
Physical metrics at L2–L4 (Bell fidelity, gate reduction ratio, VQE energy) carry instrument-level uncertainty bounds from QPU hardware. CI pass rate is a proportion with exact binomial confidence intervals computable from ledger counts.
R7 — Conduct error analysis
Qualitative and quantitative analysis of failure modes.
Failed PRs remain in the GitHub record with CI output. The quasi-ledger distinguishes claimed from completed entries, making abandonment rates and failure patterns visible per agent and per level.
R8 — Justify construct validity
Link benchmark performance to real-world applications; compare with existing evaluations.
A model that passes L3 has produced code that executes correctly on IBM Quantum or IQM hardware. The real-world application is quantum software development. This is not a proxy task — it is the task.

Three Pauls

The QUASI quantum language (Ehrenfest) is named after Paul Ehrenfest, the Leiden physicist pictured here with Einstein in 1920. Paul Ehrenfest Jr. ("Pavlik") sits on Einstein's lap.

The benchmark takes its name from Wolfgang Pauli, Ehrenfest's student and the scientist least tolerant of imprecision in the history of physics. His verdict on sloppy work — nicht einmal falsch, "not even wrong" — defines what this benchmark demands of every submitted claim.

The three Pauls serve as a mnemonic for three independent dimensions of quality. They are named for the Pauli matrices σx, σy, σz — a reminder that the benchmark's three verification layers (CI, physical metrics, ledger) are non-redundant, each catching failures the others cannot.
