I present a falsification-first experimental protocol for testing a proposed record-dependent contribution to residual dephasing in circuit-QED systems. The protocol is designed to distinguish a genuinely record-dependent residual from conventional apparatus-mediated effects introduced by manipulating record persistence itself. The protocol separates post-decoupling readiness controls from concurrent source-hypothesis tests; requires uncertainty-bounded contrasts between record-establishment conditions while controlling conventional physical channels; treats conventional explanations through calibration-compatible nuisance-model families where appropriate; and distinguishes nominal shot count from effective independent information under device, day, and miniblock correlations. It further requires operator discrimination, explicit conventional-noise accounting, preregistered decision rules, and independent device or architecture replication before any anomalous residual is eligible for escalation. A one-page laboratory handoff accompanies the paper to provide an implementation-oriented summary of the experimental decision path. Origin and relationship to prior work: This protocol was motivated by Francisco José Ruiz Izaguirre's phenomenological proposal concerning record-dependent residual dephasing (DOI: 10.5281/zenodo.22162999) and subsequent public technical exchange with the author. It is an independent falsification protocol, not an experimental confirmation of that proposal. No anomalous dephasing effect is claimed here.

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.
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.

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 record contains version 2 of the preprint “Identifiability Limits in Experimental Tests of Quantum Collapse.” It supersedes the conceptually broader first version deposited under DOI 10.5281/zenodo.19617199 and substantially revises the framing, formal results and experimental analysis. The paper formulates experimental tests of objective-collapse dynamics as an operational identifiability problem. It shows that finite accessible CPTP process statistics cannot uniformly distinguish fundamental nonunitarity from an unrestricted unitary-environment dilation. It then separates visibility loss, record formation and global measurement access, and derives a nuisance-profiled Fisher-information criterion for determining when complementary measurement channels jointly identify a shared collapse-parameter vector. A four-arm matched-control architecture is proposed that combines baseline stability, coherent reversibility, calibrated decoherence, durable-record formation and at least one independent side-effect channel. The result is a falsifiable experimental decision framework and a boundary on what accessible data can establish; it is not presented as an ontological solution of the quantum measurement problem.

This technical report develops and tests TWMSE Candidate Equation 4A, a phenomenological, threshold-activated model of observer-induced quantum collapse formulated to preserve Born weights and operational no-signalling while producing experimentally distinguishable dynamics. Candidate Equation 4A introduces a branch-sensitive Lindblad term whose activation depends on whether an operationally defined observer record exceeds a specified threshold. The report evaluates the equation’s mathematical consistency, including trace preservation, positivity, Born-weight preservation and operational no-signalling. It also examines individual stochastic trajectories, ensemble behaviour, synthetic count-level parameter recovery, statistical power and the consequences of model misspecification. A retrospective analysis is performed using published fitted GHZ decoherence-rate summaries from two superconducting-qubit studies. This is not an analysis of original laboratory shot-level data. The combined profile analysis finds no robust positive signal for Candidate Equation 4A. Instead, it establishes provisional, threshold-dependent upper limits on the additional collapse rate. Across the report’s primary threshold range of R* = 1–9, the largest pointwise one-sided 95% upper limit is approximately 7.3 × 10³ s⁻¹, while the tightest limit is approximately 3.0 × 10³ s⁻¹ at R* = 8. These are pointwise limits and do not constitute a simultaneous confidence band. The retrospective results therefore constrain but do not favour Candidate Equation 4A. Standard quantum mechanics remains sufficient to describe the analysed GHZ summaries and does so with fewer parameters. Candidate Equation 4A survives this preliminary confrontation only in the limited scientific sense that portions of its parameter space remain unexcluded. This non-exclusion is not evidence that the candidate is correct. The report consequently specifies a dedicated amplify–hold–erase experiment using matched record-forming and coherent-control circuits. The proposed test varies observer-record size, conditional record strength and dwell time while collecting count-level measurement outcomes and contemporaneous calibrations of conventional noise. The protocol is designed to distinguish a threshold-activated observer-record contribution from smooth, conventional decoherence and other experimental effects. A preregistration template, empirical-data schema and data dictionary are supplied so that the proposed experiment can be performed and analysed as an independently reproducible and falsifiable test. The accompanying ZIP archive is the complete, self-contained reproducibility package for the results reported here. It contains the code, simulation data, published GHZ rate summaries used as inputs, derived numerical outputs, documentation, software requirements and integrity checks required to reproduce the reported computational analyses and verify the packaged results. The archive contains: • the complete report in PDF, DOCX and Markdown formats;• deterministic Python reproduction scripts;• results from 500 density-matrix consistency trials;• 250,000 simulated stochastic trajectories;• 14,336 synthetic count-level circuit rows;• synthetic parameter-recovery and statistical-power results;• model-misspecification tests;• the published fitted GHZ rate summaries used in the retrospective analysis;• individual and joint GHZ profile-likelihood results;• prediction grids and report figures;• an empty 37-column template for future empirical raw data;• a data dictionary and preregistration template;• software-environment requirements and citation metadata; and• a SHA-256 manifest for package-integrity verification. The simulated trajectories and synthetic circuit counts are computational data rather than laboratory observations. The included GHZ inputs are published fitted rate summaries and are not original experimental shot counts. No new laboratory data are included, and no empirical discovery claim is made. Successful reproduction verifies that the supplied code generates the reported mathematical checks, simulations and retrospective statistical results. It does not establish that nature follows Candidate Equation 4A, demonstrate observer-induced collapse, or show that TWMSE is empirically preferred over standard quantum mechanics. The physical ideas, TWMSE framework, research direction and scientific interpretation are those of the author. Computational assistance was used for mathematical checking, simulation, statistical analysis, document preparation and reproducibility auditing. The author directed the research and accepts responsibility for the methodology, scientific claims, interpretations and conclusions. Candidate Equation 4A should therefore be understood as an explicit, internally testable and falsifiable phenomenological candidate that has passed the reported mathematical and computational consistency checks, remains compatible with the limited published summaries examined, and now requires the proposed dedicated raw-data experiment for a meaningful empirical test.
This document formulates a pre-registered falsification programme for entanglement and wavefunction-collapse phenomenology in open quantum systems. The framework adopts a register-oriented convention: an entangled AB preparation is represented as a single non-factorisable boundary-informational unit, while A and B denote locally addressable access components used in the operational workspace for control, marginalisation, tomography, and state-level entanglement readout. Measurement is described as apparatus-channel activation of an addressed logical sector. This convention fixes the interpretation of the symbols, but the tests are stated entirely in terms of operational diagnostics. The core programme compares reconstructed open-system descriptions through irreversible entropy production, entropy flux, Landauer-deficit variables, dissipator-level synchronisation, non-Markovian memory response, entanglement-sudden-death threshold timing, and Sagawa–Ueda feedback-information saturation. Five pre-registered predictions are stated. P-EC1 tests the collective-versus-local Landauer-deficit ordering in a bright-sector Dicke benchmark. P-EC2 tests the finite-rate approach of an apparatus-channel deficit toward the readout-completed asymptote under continuous diffusive monitoring, formulated on a stationary-window ensemble estimator. P-EC3 tests the spectral dependence of the non-Markovian Landauer-deficit excess. P-EC4 compares the first concurrence zero-crossing (entanglement-sudden-death threshold) with thermodynamic relaxation timing. P-EC5 tests Sagawa–Ueda bound-saturation and saturation-curve behaviour under feedback information, including an operational proxy mapping for the Yada et al. iterative-feedback anchor. Each prediction is assigned a status in a decision tree with positive controls, quantitative windows, consistency bands, platform anchors, and explicit fail conditions. The programme distinguishes worked-case consistency checks from independent-platform primary falsification tests, and separates core falsification claims from near-future or conditional routes. A boundary-clock extension is also recorded as a non-conservative layer with its own handles; its near-dark chart-inversion observable, tracked by the bounded marker η_chart(t) and the integrated observable 𝐼ₖ₅, is reported as a conditional outlook, not as a core prediction. The document therefore does not claim to derive the Born rule, prove an ontology of collapse, or modify standard quantum mechanics. It asks whether a specific boundary-persistence architecture survives a set of pre-registered operational tests.
