Experiments: Executed Benchmarks vs. Proposed Tests
This page separates executed, reproducible residual-first benchmarks from proposed falsifiable tabletop tests. The executed benchmark records are methodological and make no claim of new physical effects. The proposed roadmap describes discriminants intended to test QDL-style closure and scaling against standard parameterizations.
Use this page after reading the Framework page. Framework defines the closure and admissibility rules; this page states how those ideas are being tested, benchmarked, or turned into future experimental targets.

Program Overview
How QDL maps framework claims into auditable benchmarks and proposed discriminants.
QDL proposes a closure-based admissibility rule in a 3L + 2F basis and asks whether this rule can be tested through residual structure, scaling behavior, and discriminant signatures across multiple platforms.
- Executed benchmarks are methodological and do not claim new physics.
- Proposed experiments describe falsifiable discriminants and explicit failure conditions.
- Empirical support requires pre-stated patterns, controlled sweeps, and comparison against standard model families.
- Null results are meaningful if the failure condition was declared before the test.

Track A — Executed Benchmarks and Null Tests
Residual-first, auditable comparisons using declared model families and public or reproducible data.
Benchmarks are explicit comparisons between declared model families under a stated parameter budget, evaluated primarily by residual structure rather than aggregate fit magnitude. Each record is designed to be auditable: dataset provenance, model forms, fit controls, and residual plots are published alongside the analysis.
- Decision rule: coherent residual structure indicates model inadequacy.
- Declared parameter budget: model families are specified before fitting.
- Reproducibility: scripts, CSV files, figures, and reports are versioned with stable DOIs.
- Scope limit: benchmarks test method discipline, not final physical interpretation.
These benchmarks are evidence for audit discipline; they are not presented as standalone validation of QDL’s strongest cross-domain physical claims.
- Benchmarks and null tests: 10.5281/zenodo.18057668
- NV-center ODMR benchmark: 10.5281/zenodo.18069870
- Optical cavity trace benchmark: 10.5281/zenodo.18076864
Each record is intended to make provenance, preprocessing, model families, and residual structure inspectable.
1. Optical Cavity Resonance Benchmark
Residual-first diagnostics distinguish stabilized traces from uncontrolled resonance scans. Coherent residual structure is treated as a sign of model inadequacy rather than automatically as new physics.
DOI: 10.5281/zenodo.18076864
2. NV-Center ODMR Benchmark
Residual-first benchmarking compares baseline spin-Hamiltonian fits with a strictly reduced comparison family using public ODMR data, emphasizing structural adequacy rather than fit magnitude alone.
DOI: 10.5281/zenodo.18069870
3. Benchmarks and Null Tests
Defines residual-first reporting conventions and provides executed null-test anchors where a reduced family is expected to pass if no additional structure is present.
DOI: 10.5281/zenodo.18057668
- Public provenance: datasets are linked with stable identifiers.
- Declared preprocessing: no hidden filtering, windowing, or cherry-picked segments.
- Declared model families: reduced and baseline comparisons are explicit.
- Declared parameter budget: added flexibility must be disclosed.
- Residual-first reporting: residual structure is treated as primary evidence.
- Scope discipline: method results are not overstated as new physical effects.
This discipline is designed to avoid ambiguous “fit improvement” narratives and enable clear success or failure judgments that other groups can reproduce.
How to Interpret Results
A compact decision tree separating benchmark adequacy from empirical support for QDL-specific discriminants.
Benchmark passes: residuals are noise-like under the declared reduced family. This supports adequacy of that reduced family for the dataset under the stated pipeline choices.
Benchmark fails: coherent residual structure persists. This indicates model inadequacy or pipeline artifact; it does not by itself identify missing physics.
Discriminant test supports QDL: a pre-stated QDL-distinct scaling or pattern appears under controlled sweeps, while the standard comparison family fails to match it within uncertainty without erasing the constraint by adding flexibility.
The page is structured to reduce scope creep: benchmarks are method; discriminants are physics tests.
QDL-adjacent analyses often involve re-expression through units, bases, or measurement-chain parameterizations. This page treats unit changes, basis reparameterizations, and explicit measurement-chain re-expression as audit transforms when they are declared in advance.
Transforms that change model class, introduce undisclosed calibration degrees of freedom, or alter data selection are interpretation changes and must be declared as such.
This rule is intended to prevent post-hoc reinterpretation under a different analysis choice.
| Executed benchmark | A reproducible methodological test of residual structure or audit logic. It does not claim a new physical effect. |
| Proposed discriminant | A pre-stated test target that could support or weaken a QDL-specific scaling or closure claim if executed under controlled conditions. |
| Positive result | Requires pre-stated pattern, controlled sweeps, residual-first reporting, and failure of standard comparison without extra flexibility. |
| Negative result | Counts as meaningful if the failure condition was declared in advance and the sensitivity was adequate. |
| Ambiguous result | Requires more controls, better provenance, tighter budgets, or stronger separation between constrained and unconstrained model families. |
Track B — Proposed Falsifiable Tabletop Tests
Four complementary platforms. Each block states a proposed discriminant and an explicit failure condition.
- Declare constrained and standard model families.
- Run a geometry or configuration sweep.
- Evaluate residual structure with fixed parameter budgets.
- Use benchmark workflow as method precedent.
- Pre-register a sweep and constrained discriminant.
- Hold calibration degrees fixed and report residual-first.
- Use existing apparatus for geometry or material sweeps.
- Test constrained scaling against standard families.
- Failure means no discriminant or only extra-flexibility success.
- Find or construct a dataset with a clean sweep axis.
- Declare a constrained collapse target.
- Collapse must beat flexible refits under fixed budgets.
The protocol describes candidate discriminants across platforms. This page presents them as proposed tests until independently executed by experimental groups.
Torsion-Balance Experiments
Scaling discriminants versus geometry and mass configuration.
Precision torsion balances are sensitive to small forces and allow controlled sweeps of geometry and configuration. QDL proposes that certain admissibility or closure constraints may translate into discriminant scaling patterns under these sweeps.
This is presented as proposed. The recommended pathway is sensitivity-first.
- Identify an existing torsion dataset suitable for a geometry or configuration sweep.
- Declare the standard and constrained model families.
- Declare parameter budgets before fitting.
- Run the sweep and report residual structure as the primary diagnostic.
- Publish null results if the failure condition is met.
NV-Center Frequency Shifts
Discriminants under controlled field and geometry sweeps.
NV centers provide a precision probe with controllable environments. QDL proposes that constrained combinations of fields, geometry, and constants may yield discriminant patterns under structured sweeps.
This is presented as proposed physics testing. The executed benchmark below is methodological.
- Executed benchmark: 10.5281/zenodo.18069870
- Proposed discriminant: pre-register a sweep and constrained family.
- Analysis discipline: keep benchmark and physics discriminant logically separate.
- Reporting: publish residual-first results, including null results.
The existing benchmark shows workflow discipline. It does not claim a new NV-center physical effect.
Cavity Length-Frequency Scaling
Geometry and material sweeps as clean L-F probes.
Cavity resonators tightly couple length and frequency and are well-suited to controlled sweeps. QDL proposes discriminant scaling constraints in an L-F basis that can be tested against standard parameterizations.
This is presented as proposed physics testing. The executed benchmark is methodological.
- Executed benchmark: 10.5281/zenodo.18076864
- Proposed discriminant: pre-register sweep and constrained model family.
- Minimum practical route: repurpose existing cavity apparatus into geometry or material sweeps.
- Reporting discipline: publish residual plots, null tests, and parameter budgets.
The roadmap aims for low-barrier repurposing of existing cavity apparatus into discriminant sweeps.
Metamaterial Coherence and Dispersion
Dispersion-collapse candidates as discriminant signatures.
Metamaterials allow engineered dispersion and controlled effective parameters. QDL proposes that certain “locked” combinations may yield discriminant collapse behavior under designed sweeps.
This is presented as proposed. Suggested pathway:
- Identify an existing metamaterial dataset with suitable sweep structure.
- Declare constrained versus unconstrained model families.
- Declare parameter budgets before fitting.
- Report residual-first and treat collapse claims as falsifiable targets.
- Publish null results if constrained collapse does not appear.
The goal is to avoid “it could be” narratives by making the discriminant and failure condition explicit.
FAQ: Scope and Falsifiability
Short answers to prevent over-interpretation.
No. The executed benchmarks are methodological and do not claim new effects. The tabletop discriminants are proposed tests with explicit failure conditions, presented as targets until independently executed.
A pre-stated discriminant scaling or pattern appears under controlled sweeps, and the standard comparison family fails to reproduce it within uncertainty without extra degrees of freedom that erase the discriminant.
The QDL-constrained family fails across the sweep within uncertainty, or it only matches after adding ad hoc flexibility that nullifies the constraint’s meaning.
Benchmarks provide evidence of auditability and a residual-first adequacy workflow. They are not presented as standalone validation of the strongest cross-domain QDL physics claims.
Collaboration and Data
How experimental groups can engage, replicate, or refute.
Collaboration is most valuable when it sharpens falsifiability and reduces interpretive wiggle room.
- Replicate an executed benchmark using the same record and artifacts.
- Propose a platform sweep with a pre-stated discriminant and failure condition.
- Publish residual-first reporting, including null tests, regardless of outcome.
- Declare standard and constrained model families before analysis.
- Declare parameter budgets, calibration degrees of freedom, and sweep axes in advance.
The aim is to make success and failure equally publishable by design.

For a proposed discriminant test, the most helpful first step is a short sensitivity note: what sweep is feasible, what noise floor dominates, and what failure condition is credible.
