Ultra-High-Isolation Null-Channel Metrology for Weakly Coupled Microwave Photon-Regeneration Experiments Ultra-weak microwave photon-regeneration experiments face a measurement problem that can become more important than detector sensitivity itself: an apparent regenerated signal may instead be ordinary electromagnetic leakage from the source into the receiver. This methods paper develops a falsifiable metrology framework for placing a quantitative upper bound on conventional source-correlated power that can occupy the same receiver mode as a hypothesized weak signal. The central observable is the receiver-mode equivalent leakage ceiling, denoted \(P_{\mathrm{leak},95}^{\mathrm{eq}}\): a 95% upper confidence bound on conventional source-correlated power after the experiment's accepted spectral, spatial, phase, temporal, and polarization conditions are applied. The framework distinguishes raw enclosure attenuation, end-to-end source-to-receiver transfer, and receiver-mode isolation. These quantities are not treated as interchangeable. The proposed Stage-L0 validation sequence contains four layers. Component characterization measures individual shielding stages, penetrations, cables, grounds, filters, control paths, and other plausible coupling routes. Integrated null-channel testing then measures the complete source-to-receiver transfer function rather than inferring system performance by adding nominal attenuation values. Adversarial injected-leak tests deliberately introduce calibrated conventional signals and verify that the apparatus and analysis recover them near the claimed exclusion boundary. Finally, a long-duration blinded validation stage measures drift, guard bands, receiver-mode discrimination, false positives, and run-duration stability. For potentially coherent leakage paths, the method combines upper bounds conservatively at the field-amplitude level rather than adding decibel values. When a genuine physics-null state is available, it may support direct null estimation only after transfer congruence is demonstrated. When no valid physics null exists, the candidate science response is prohibited from estimating its own leakage background; the conventional ceiling must instead be constructed independently from validated leakage paths. The manuscript derives confidence-region and injected-signal detection thresholds for a complex transfer coefficient and provides synthetic validation of the statistical procedure. These synthetic calculations test the analysis method; they are not experimental Stage-L0 data. A worked power-budget example shows how a target signal floor can be translated into a required equivalent isolation threshold. The primary decision rule is \(P_{\mathrm{leak},95}^{\mathrm{eq}} < \epsilon P_{\mathrm{target}}\), with the margin \(\epsilon\) fixed before validation. Failure to satisfy this condition blocks interpretation of a downstream weak-regeneration search but does not itself falsify any underlying particle or field hypothesis. The method is intended to be useful independently of any specific exotic-physics model, including microwave light-shining-through-wall searches, hidden-sector searches, cavity-to-cavity weak-coupling experiments, and other measurements where conventional cross-talk can mimic an ultra-weak signal. A companion reproducibility package contains the frozen equations, decision rules, synthetic-validation code, tests, expected outputs, assumptions, and falsification records. No empirical Stage-L0 dataset or exotic-physics detection is reported.

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.
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 preprint develops a staged framework for testing whether matter-wave dynamics contain a source-dependent reciprocal contribution beyond ordinary phase evolution. The conceptual motivation comes from the asymmetry of standard pilot-wave theory, in which the wave guides material configurations without an established reciprocal action of those configurations on the wave. The proposed approach represents any candidate back-reaction through an effective scalar–vector connection and uses matched matter-wave states with opposite phase gradients as a symmetry-based lock-in test. Ordinary phase motion reverses between the two states, whereas a source-fixed reciprocal contribution would remain as a measurable common-mode residue. The experimental program begins with calibration using a known synthetic gauge field in an ultracold-atom platform. It then advances to a source-free null campaign, followed by a blinded four-state experiment combining phase reversal with reversal of a compensated polarized-spin source. Candidate signals would be tested through source parity, internal-state and species dependence, distance scaling, modulation-frequency response, circulation, curl, and spacetime-holonomy measurements. A coherent counterpropagating Bragg-pair readout and numerical source-to-signal benchmarks are developed to estimate the required phase sensitivity and identify dominant backgrounds. The interpretation is deliberately hierarchical. A nonzero residue would first indicate an unexplained source-dependent interaction; additional evidence would be required to establish connection-like behavior, compatibility with an axial-vector or contorsion effective theory, or genuine pilot-wave back-reaction. Null results would still provide model-independent bounds. If interested please request experimental brief, source code, numerical data, figures, and reproducibility documentation.
T79 completes the Q5 interferometric falsification framework by introducing a structured null-control protocol for quadrature-cycling residuals. Earlier theorems established the residual form, the Z4 quadrature-cycling structure, statistical thresholds, magnitude estimates, and systematics discrimination criteria. T79 addresses the final degeneracy problem: the cycling defectIQ5=∑k=03∣vk+1−Jvk∣2can vanish trivially when all quadrature vectors are zero. The theorem, therefore, establishes the joint operational requirementIQ5≈0and∣vk∣≈0,ensuring that the detected structure corresponds to nontrivial quadrature transport rather than the simple absence of signal. The theorem then defines four explicit null-control experiments designed to isolate ordinary instrumental artifacts from candidate Q5-consistent cycling structure. These include blocked-path operation, detector-only measurements, intentional laser-power modulation, and a classical phase-reference channel. Each control specifies a concrete pass condition under which stable, nonzero quarter-cycle transport behaviour must disappear or fail to persist. In particular, blocked-path operation forces P1P2=0, eliminating the interference residual derived in T72, while detector-only and reference-channel measurements test whether the observed cycling behaviour originates from instrumentation rather than coherent transport structure. T79 reframes the experimental objective as layered falsification rather than direct proof. A candidate signal survives only if coherent two-path interference exhibits nonzero stable quadrature vectors satisfying the quarter-cycle rotation law, while all null controls fail to reproduce the same structured behaviour. The theorem, therefore, converts the earlier invariant framework into a hardened experimental protocol capable of rejecting broad classes of ordinary systematic effects without claiming definitive proof of Q5 transport itself. Passing the protocol establishes only that the observed cycling behaviour survives the identified null controls and remains structurally consistent with the Q5 quadrature-transport prediction. Status: solid for the joint nontriviality condition IQ5≈0 together with ∣vk∣≈0; solid for the blocked-path null implied by the T72 interference structure; solid that the four null controls define experimentally testable falsification operations; conditional on whether the listed controls exhaust all relevant systematic classes for a given experimental platform; not a claim that passing the full null-control protocol would uniquely establish Q5 transport physics.
This version develops a preregisterable and falsifiable experimental framework for investi-gating parametric optical amplification of weak biomedical signals.The framework explicitly distinguishes spontaneous parametric down-conversion fromseeded parametric amplification and treats the latter as the primary amplification mechanism.The signal path is modeled asweak optical input → parametric amplifier → loss/filtering → detector → statistical inference.The theoretical model is based on a two-mode Bogoliubov transformation,aˆs,out = uaˆs,in + vaˆ†i,in,with|u|2 − |v|2 = 1for the ideal lossless case.The framework separately models amplifier gain, quantum noise, optical loss, detectorinefficiency, electronic noise, pump noise, phase noise, mode mismatch, gain saturation, andpump depletion.Two operating modes are considered:1. phase-insensitive amplification, in which both quadratures are amplified and unavoidablequantum noise is introduced;2. phase-sensitive amplification, in which one selected quadrature can be amplified withlower added noise under appropriate phase matching.The primary endpoint is a prespecified detector-level signal-to-noise metric comparing theparametric amplifier with a gain-matched reference architecture.Secondary endpoints include the measured noise figure, effective gain, detection threshold,and downstream classification performance.The v3.1 framework introduces preregistered performance thresholds, a locked test set,independent calibration, blocked randomization, blinded analysis where feasible, hierarchical. statistical models, uncertainty propagation, multiplicity control, negative-control experiments,saturation diagnostics, and explicit falsification criteria.The proposal does not claim a universal amplification advantage, quantum supremacy, orclinical diagnostic capability.
