REAL-04A is a preregistration-style experimental protocol designed to test whether two inverse contextual histories can leave a measurable residual difference after a verified physical reset. The protocol compares two ordered histories, H_A: C_1 -> C_2 -> C_3 -> C_1 and H_B: C_1 -> C_3 -> C_2 -> C_1, followed by a reset operation and an independent final readout. The primary null hypothesis is that the final outcome distributions are identical after verified reset. The primary statistic is the total variation distance between the two final distributions, evaluated with block-permutation testing and bounded against preregistered nuisance contributions, including leakage, drift, apparatus memory, reset failure, and finite-sample error. The protocol is intended as a conservative, falsifiable test of residual history-dependence. It does not report experimental data and does not claim evidence for new physics.

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 preregistration describes a confirmatory study of an upstream conditioning architecture in a quantum error-correction workflow. The project’s purpose is to test whether an intervention applied prior to the primary decoder produces a real and reproducible decoder-relevant effect, remains compatible with more than one downstream decoder family, generates a measurable exposed-observable statistical footprint, and improves or preserves performance across a preregistered regime rather than only at a single operating point. The study is intentionally limited to architecture-level evaluation, with the public claim set confined to exposed observables, frozen transformations, preregistered statistical tests, explicit negative controls, and bounded interpretation rules. The confirmatory design is organized around five preregistered tests: category existence, decoder compatibility, structural footprint, observable statistical signature, and regime robustness. Across these tests, the central comparison is between a baseline control pipeline and a conditioned pipeline in which the upstream intervention is applied while all non-conditioning settings are held fixed. The study uses frozen observables and frozen execution rules, including matched seeds, shot counts, code distances, physical error rates, geometry, and baseline decoder settings, so that any supported effect can be interpreted as evidence about the architecture under test rather than as a byproduct of post hoc tuning. To preserve a clean-room boundary, the registration restricts primary analysis to exposed, decoder-facing quantities only. These include logical failure, an exposed defect-count summary, and an exposed decoder-difficulty proxy, along with a locked scalar error-load construction derived from control-only standardization. The study does not rely on decoder-internal state variables, hidden confidence traces, or implementation-specific internal diagnostics in its primary confirmatory analyses. This structure is intended to let readers evaluate whether the architecture leaves a reproducible footprint in decoder-facing behavior without disclosing reconstruction-level mechanism details. Expected outcomes are defined in confirmatory rather than speculative terms. If the preregistered hypotheses are supported, the study is expected to provide evidence that an upstream conditioning intervention exists as a real architectural category in QEC, acts before the primary decoder, is compatible with downstream decoding, changes decoder-relevant exposed structure, and produces a reproducible observable statistical footprint in logical-failure behavior. If support is absent, mixed, or null, those outcomes will still be recorded under the frozen rules without rescue through post hoc metric changes, reweighting, or reinterpretation. In either case, the expected result of the registration is a bounded, auditable public record of whether this architecture class shows reproducible category-level behavior under a preregistered confirmatory design. The preregistration is not intended to establish a unique mechanism identity, identify a privileged implementation, disclose implementation-specific reconstruction details, or support claims about exact targeting logic, suppression laws, subset-sizing logic, telemetry-governed control, or broader cross-domain theory narratives. Public-facing interpretation is therefore intentionally limited to category validation and exposed-observable behavior. This is meant to support rigorous public evaluation while preserving strict clean-room limits around protected implementation detail.
Exploratory experimental quantum-preparation preprint investigating whether prior state-transition history can leave measurable residual timing signatures after a quantum system has stabilised into an identical repeated final state. The work proposes a falsifiable high-statistics timing experiment comparing direct state preparation against deep alternating preparation histories, while measuring only during the stabilised phase. The framework includes timing-resolved observables, decay analysis, systematic controls, sequence inversion tests, statistical sensitivity estimates, and reproducibility pseudocode using modern photonic timing hardware. Intended as an experimental proposal rather than a claim of established non-standard quantum behaviour.
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.
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.
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.
