TSR-Q-1 presents a preregistered and falsifiable experimental protocol designed to test for structured late-time coherence residuals in superconducting transmon qubits. The protocol does not treat generic recoherence, non-exponential decay, or non-Markovian behavior as evidence for the proposed framework, since such phenomena may arise from conventional open-system mechanisms. Instead, it targets a specific normalized temporal scaling law, tₙ/T₂ = nᵏ, with the preregistered theoretical value k* = 1.4706, corresponding to the first two target locations t₂/T₂ = 2.7714 and t₃/T₂ = 5.0310. If the associated amplitude-scaling hypothesis is retained, the predicted ratio is A₃/A₂ ≈ 0.551. The accompanying computational validation package develops the analysis pipeline through five stages: preliminary signal injection, blind null testing, blind injection-recovery, multi-qubit global-k inference, and sensitivity mapping. The synthetic null models include stretched-exponential decay, 1/f^α correlated noise, random-telegraph/TLS-like contributions, slow drift, white noise, and device-to-device variability. These simulations validate the detectability, specificity, and sensitivity of the proposed analysis procedure under the tested synthetic noise families. They do not constitute experimental evidence for the existence of the predicted physical effect. The next stage is a preregistered hardware implementation using superconducting qubits, with device-specific null calibration, blind analysis, systematic controls, held-out replication, and, ultimately, independent experimental replication.

This manuscript presents a methods-forward, operational protocol for evaluating whether any structured dependence remains in quantum-computing measurement records after explicit modeling of standard quantum and device-level mechanisms. Classical definiteness is defined at the record layer, and pre-record states are treated as predictive descriptions rather than as classical outcome facts. Within this operational stance, the protocol converts questions about outcome status and record formation into a falsifiable test program grounded in preregistered analysis rules and standard measurement telemetry. A locked null-model family is specified in advance, incorporating standard quantum dynamics together with documented device-level mechanisms including drift, correlated and non-Markovian noise, crosstalk proxies, and leakage indicators. The framework provides operational definitions, a conservative postulate set, preregistered endpoints, residual-adjudication criteria, negative controls, a fixed windowing discipline, and a bound-first reporting standard designed to yield informative constraints under null results. Any candidate contribution beyond the declared null family must appear as structured, reproducible residual dependence that survives the locked null family and the full residual-filter sequence. Version 4.4 refines the protocol specification, clarifies evidentiary boundaries, and strengthens the integration of the synthetic demonstration. The manuscript includes a fully specified classical simulation that executes the decision pipeline under controlled conditions. The synthetic study illustrates how the protocol classifies a bounded-null case, a measured-artifact case, a partial-artifact/unresolved-covariate case, an injected structured-residual case, and a failed-topology case. This demonstration establishes computational executability of the protocol and clarifies the behavior of the decision tree, but it does not constitute empirical evidence for any physical mechanism. Because the protocol relies only on standard measurement telemetry and preregistered analysis rules, it is directly implementable across contemporary quantum-computing platforms and does not depend on any single dataset, backend, or hardware realization. The manuscript is a specification paper: it defines a reproducible evidentiary framework for record-level claims, while large-scale empirical implementation, hardware benchmarking, and cross-platform replication remain subsequent studies.
We report evidence consistent with non-exponential decoherence in superconducting transmon qubits. Ramsey interferometry data from five qubits on IBM Quantum hardware show that a stretched-exponential model f(t) = exp(-(t/T2 ) beta) fits the observed decay better than the standard exponential (beta = 1). On our primary qubit (Q0), we measure beta = 2.06 with R2 = 0.9964 versus R2 = 0.9586 for the exponential, with Bayesian Information Criterion favoring the stretched model by 46 units. While non-exponential decay in superconducting qubits has been previously observed in the context of 1/f noise [4], the present work provides a systematic multi-qubit characterization with a fully reproducible protocol and proposes a falsifiable geometry-dependent prediction (RAB != 1) that distinguishes this framework from collapse-model alternatives.
This work develops a phenomenological model of residual decoherence in superconducting transmon qubits within the framework of State Locality Theory (SLT‑2). The model treats a qubit as a stable localized field configuration and introduces a frequency‑dependent localization rate that increases at lower transition energies. Using phenomenologically calibrated parameters, the model predicts a fundamental coherence‑time ceiling in the millisecond range and yields a falsifiable experimental signature: after subtracting all known noise mechanisms, the remaining decoherence rate should scale linearly with the inverse qubit frequency. Comparison with recent state‑of‑the‑art devices suggests that the SLT‑2 contribution may already constitute a significant fraction of the residual decoherence budget in low‑frequency qubits. The work also outlines an experimentally accessible protocol for testing this prediction using tunable‑frequency transmons. Additional SLT‑2 materials, extensions, and working notes are available in the associated OSF project: 10.17605/OSF.IO/CMVJ5.
Residual Quantum Information Persistence Under Native Decoherence: A UIPO-Governed CS2 Precursor Protocol for Prospective Quantum Model-Adequacy Testing Author: Kevin L. BrownResearch Status: Falsifiable hypothesis and preregistration-grade experimental protocol; no empirical result is claimed. This paper presents a prospective experimental protocol for testing whether measurable quantum-state information persists longer than a preregistered family of conventional decoherence models predicts. The proposed experiment uses a superconducting transmon qubit prepared in opposing equatorial quantum states. State distinguishability is reconstructed through single-qubit tomography and quantified using trace distance as the system evolves under native decoherence. The central hypothesis, H-QRP-1, asks whether normalized quantum-state distinguishability exhibits a reproducible positive residual beyond three preregistered parametric comparator models: exponential decay, stretched-exponential decay, and damped-revival dynamics capable of representing conventional memory effects. A Gaussian-process model is included separately as an empirical flexibility control to determine whether any residual structure remains statistically predictable even when the simpler parametric models fail. The protocol is designed to minimize post-hoc interpretation. It specifies state preparation, readout calibration, T1 and T2∗ calibration, tomography reconstruction, dimensional normalization, comparator equations, parameter bounds, optimization procedures, randomization, validation rules, uncertainty propagation, serial-dependence controls, sample-size determination, practical-effect thresholds, and confirmatory decision criteria before evaluation data are collected. The calibration program is divided prospectively into independent model-fitting and calibration-validation stages. Serial dependence across device days is handled through preregistered circular moving-block simulations using multiple dependence lengths. The final evaluation sample size is selected only if the complete decision procedure satisfies predefined false-positive and statistical-power requirements. A positive result would not by itself demonstrate new quantum physics, validate the Unified Informational Physics Ontology (UIPO), confirm Triune Harmonic Dynamics (THD), or invalidate quantum mechanics. It would establish only that the registered conventional parametric model family systematically underpredicts measurable state distinguishability under the tested conditions. The proposed escalation path requires independent hardware replication and stronger conventional characterization, including process-tensor methods, before any mechanism-specific interpretation is considered. The broader practical question is whether quantum information currently treated as effectively lost during decoherence may contain additional measurable and potentially recoverable structure. If independently validated and shown to be usable, such residual persistence could eventually inform quantum-memory modeling, error-correction strategies, qubit control, and quantum-hardware design. THD-specific testing is explicitly excluded from the active hypothesis until an author-approved mapping from the canonical THD structure to measurable quantum observables is prospectively defined and preregistered.

This document fixes, before the data exist, the hypothesis, apparatus, observables, cadence, analysis, thresholds, controls, stopping rule and reporting commitment of a one-year search for a modulation of superconducting-qubit energy relaxation (T1) at the sidereal frequency, 1/(23 h 56 m 4.09 s), beyond what the solar day and its seasonal modulation can produce. Data collection began on 17 October 2026 at 16:42 UTC on qubit 9 of the IBM Heron processor ibm_fez: an eight-delay inversion-recovery T1 measurement every six hours (about 3 s of processor time each), with the device's calibration values polled hourly. The analysis is fixed in advance: a least-squares fit of a smooth drift plus sinusoids at the solar, sidereal, anti-sidereal and extended-sidereal frequencies, with the reported amplitude leakage-corrected as sqrt(A_sid^2 - A_anti^2) (Farley and Storey 1954). The pipeline was validated on synthetic data before the first measurement and recovers an injected 0.3% at 2.7-3.4 sigma while returning 0.5 sigma with nothing injected. Detection requires a leakage-corrected amplitude at or above 3 sigma, both control channels below 2 sigma, a phase stable between the two halves of the year, and survival when runs adjacent to calibrations are removed; otherwise the result is the 95% upper limit, expected near 0.3%. The search is declared inconclusive if fewer than 900 of 1460 scheduled runs succeed or the anti-sidereal control exceeds 3 sigma. An amplitude matching the known cosmic-ray anisotropy (~0.1%) is a calibration, not a discovery. Stopping rule: one year, with a six-month interim look at the controls only; a second year is pre-declared as the response to an inconclusive or 2-3 sigma outcome. The result will be reported whether it is a detection, a bound, or a failure of the apparatus. Standard physics predicts a null result at this sensitivity; the alternative hypothesis is from The Cosmic Page (doi:10.5281/zenodo.23287018, Ch. 13) and the research proposal doi:10.5281/zenodo.23201109.

In superconducting quantum circuits, decoherence improvements are frequently obtained through process interventions that simultaneously modify surface chemistry, microstructural topology, and device geometry, leaving mechanistic attribution structurally underdetermined. Predictive materials engineering requires measurable structural statistics to be separated from geometry-dependent coupling coefficients into independently testable factors. We introduce the concept of classical and quantum microstructure. In that context, we formulate a channel-wise separable framework for decoherence in superconducting transmon qubits in which each loss channel is described by a reduced prescriptor. Here, a channel-specific microstructural state variable is determined independently of device geometry, and a geometry-dependent coupling functional is computable from field solutions without reference to surface chemistry. We derive this product form from a spatially resolved kernel representation and establish a perturbative separability criterion that defines the regime where independent variation of the variables is valid. The framework specifies five prescriptor classes for dominant loss pathways in transmon-class devices. Falsifiability is operationalized through a pre-committed 2x2 experimental protocol in which the variables must satisfy independent ratio checks within propagated uncertainty. A Minimum-Dataset Specification standardizes reporting for cross-laboratory inference. Part I establishes the conceptual and mathematical architecture; coordinated experimental validation is reserved for Part II.
