Reconstructed Efficiency Parameters from Superconducting Qubit Relaxation Data

This dataset provides operational validation data used as a proof-of-concept example in a study of admissibility constraints for irreversible physical updates. It documents eight independent quantum measurement scan runs performed on IBM Quantum backends Fez and Marrakesh. The dataset demonstrates independent extraction of energetic cost, informational entropy change, and an effective bandwidth proxy under declared operational definitions. An efficiency parameter is inferred as a diagnostic quantity without fitting, optimization, or interpretive assumptions. The dataset is provided for reproducibility and methodological transparency. It does not assert universality, cross-domain invariance, or any interpretation of quantum measurement, and it does not depend on any broader theoretical framework. Version update (interpretive alignment and documentation refinement). This version supersedes the previous release to align dataset documentation with a newly prepared manuscript on admissibility constraints for irreversible physical updates. No raw data, scan results, or numerical values have been modified. All CSV files, reconstructed quantities, and checksum hashes remain unchanged. Changes in this version are limited to: clarification of interpretive scope (proof-of-concept validation only); removal of language implying universality or cross-domain invariance; explicit alignment with an admissibility-constraint framing rather than a framework-specific interpretation; updated summary and metadata text to support transparent peer review and reproducibility. This update ensures consistency between the dataset and its use as a validation example in a theory-agnostic admissibility study, without altering any underlying measurements or analysis outputs.
