Quantized Dimensional Ledger (QDL)

QDL is a proposed pre-dynamical admissibility framework for analyzing dimensional representations of physical models in a single, explicit ledger language.

Scope & limits (read this first):

QDL is not a replacement for quantum field theory, general relativity, or effective field theory. It proposes a structural constraint layer that can be tested through basis-invariance checks, scaling behavior, and closure consistency on declared model families. If empirically successful models systematically violate ledger closure under declared transforms, the closure postulate is falsified.

Intended role: a constraint layer on admissible representations — not a claim of new particles, forces, or dynamics.

Dimensional Admissibility & Measurement Integrity

A framework-independent, standards-ready audit layer for model-driven energy and infrastructure systems.

Standards-ready translation
From QDL-origin insight to national-scale model governance

This work originated in the Quantized Dimensional Ledger (QDL) research program, where strict dimensional bookkeeping repeatedly exposed decision-level inconsistencies in otherwise well-posed models. By separating that observation from QDL’s broader physical claims, the paper extracts a general, falsifiable principle— dimensional admissibility—and translates it into a standards-ready audit framework applicable to model-driven energy and infrastructure systems. No QDL assumptions are required for its use.

This standards framing is intentionally independent of QDL’s broader theoretical program. Its purpose is to make representational invariance testable, reportable, and auditable across real-world optimization and planning pipelines.

Latest Results

Three executed, reproducible residual-first benchmarks using public data across metrology-relevant domains.

Residual-first benchmarking treats coherent residual structure as the primary model-adequacy diagnostic under declared model families and a stated parameter budget. These records are designed for straightforward external replication. No new physical effects are claimed; the contribution is methodological.

Experimental Program

QDL is designed to be testable. The experimental validation roadmap focuses on four complementary tabletop platforms that probe QDL-driven scaling and closure claims in distinct physical regimes.

Validation roadmap
Falsifiable tests of a 3L + 2F ledger

The QDL Experimental Validation Protocol outlines how a proposed conserved Quantized Dimensional Cell could leave measurable signatures in precision experiments. Each platform is designed so that standard theories and QDL give clearly distinguishable scaling behavior under declared transforms.

  • Precision torsion-balance scaling – torque and deflection vs. arm length and mass structure.
  • NV-center frequency-shift measurements – structured offsets in spin resonance under QDL-motivated fields.
  • Cavity-mode length–frequency scaling – resonance structure vs. cavity geometry in the L–F ledger.
  • Metamaterial dispersion-collapse tests – engineered media approximating QDC-like coherence.

Why QDL Matters

A concise view of how the QDL program fits into 21st-century theoretical and experimental physics.

QDL proposes a dimensional-closure admissibility architecture intended to complement (not replace) established physical theories. The core claim is structural: whether a conserved ledger target and closure rule can constrain admissible representations in a basis-invariant way.

The Institute’s goal is to make every step—from ledger construction to benchmark design—transparent and externally checkable, with clearly stated assumptions, transforms, and failure conditions.
