Formal Execution Semantics and Governance Invariants for Hybrid Classical-Quantum Autonomous Systems

Abstract

The increasing adoption of autonomous systems, artificial intelligence (AI), Large Quantitative Models (LQMs), high-performance computing (HPC) infrastructures, and quantum computing introduces new challenges for execution-layer governance. Existing governance models frequently assume deterministic execution environments in which proposed actions, execution outcomes, and resulting state transitions can be evaluated using deterministic semantics. Emerging computational systems increasingly violate these assumptions by producing probabilistic outputs, confidence intervals, uncertainty distributions, optimization result spaces, and quantum measurement distributions. This paper extends prior work on Artificial Intelligence Governance Control Planes (AGCPs), formal execution semantics, and Quantum Runtime Governance by introducing a formal execution model for hybrid probabilistic execution environments spanning classical systems, HPC infrastructures, AI systems, LQMs, and quantum computing resources. The paper formalizes the concepts of Probabilistic Admissibility and Replay-by-Distribution, demonstrating how deterministic governance authority may be preserved even when governed execution environments exhibit probabilistic behavior. Building upon previously proposed Quantum Runtime Governance Invariants, the paper develops a mathematical formalization of governance-preservation properties and establishes a collection of governance-preservation theorems addressing commit safety, governance continuity, hybrid execution graph safety, replayability, auditability, and non-bypass execution. The analysis demonstrates that governance authority, authorization integrity, admissibility integrity, provenance continuity, and commit-bound control can remain preserved across heterogeneous execution environments despite probabilistic computational behavior. The paper argues that quantum computing is not an isolated governance challenge but rather an instance of a broader class of probabilistic execution systems. Accordingly, the work provides a foundation for extending execution-layer governance into future computational environments that combine classical computing, artificial intelligence, quantitative modeling, quantum computing, and autonomous decision-making systems.

Toward Quantum Runtime Governance: Execution Invariants and Governance Requirements for Quantum and Hybrid Quantum Systems

John Willis

Existing artificial intelligence governance and runtime execution governance frameworks were developed primarily within classical computing environments. While autonomous and agentic systems have introduced new governance challenges, most governance architectures continue to rely upon assumptions regarding deterministic execution, reproducibility, authorization validity, and auditability. Quantum and hybrid classical-quantum systems introduce execution characteristics that challenge these assumptions. Probabilistic measurement, circuit compilation and transpilation, hardware-dependent execution behavior, calibration drift, shot-based execution, hybrid computational workflows, and emerging distributed quantum architectures create governance obligations not fully addressed by existing execution-governance models. This paper proposes an extension of execution-layer governance into quantum environments through the introduction of Quantum Runtime Governance Invariants and corresponding Quantum Governance Requirements. The proposed invariants identify governance properties that must remain true regardless of implementation details, hardware platforms, programming models, or execution environments. These invariants are explicitly tied to governance properties including authorization integrity, admissibility integrity, provenance continuity, governance evidence integrity, replayability, governance continuity, and governance authority. The paper further introduces the concept of Probabilistic Admissibility, in which governance systems evaluate and authorize bounded outcome distributions rather than deterministic outcomes. Building upon this foundation, the paper derives a structured set of Quantum Governance Requirements spanning quantum resource governance, circuit governance, compilation governance, probabilistic outcome governance, shot governance, calibration governance, hybrid classical-quantum governance, quantum artificial intelligence governance, and distributed quantum governance. Finally, the paper examines the implications of these concepts for the Artificial Intelligence Governance Control Plane (AGCP), arguing that quantum systems do not require a fundamentally new governance architecture. Rather, they require an extension of existing execution-governance semantics capable of operating over probabilistic execution environments. The resulting framework establishes an initial foundation for AGCP-Quantum profiles, governance conformance assessment methodologies, registry assessment frameworks, governance assurance models, and future standards development activities.

Trivian Relational Architecture Beyond Classical Computation: A Compatibility Analysis and Research Agenda for Hybrid AI–Quantum Systems

Sarasha Elion

Hybrid AI–quantum workflows distribute computation, interpretation, and action across systems with different execution conditions and authority boundaries, a result can remain technically valid even after the context or authorization supporting its use has changed. This paper develops a philosophical and architectural account of those transitions through the Trivian Relational Architecture, arguing that governing heterogeneous computation requires attention to the relationships through which evidence is interpreted, authority is delegated, and decisions become consequential. It introduces a contextual, multi-role ontology distinguishing participants, computational resources, environmental interfaces, and governance authorities, then maps the five existing Trivian components (Relational Field Constants, Syzygy Rosetta, Coheronmetry, Orthogonal Signal, and the Trivian Resonance Lattice) to hybrid workflows — developing extensions for intent-bounded delegation, execution-linked provenance, resource-bounded authority, and action-time eligibility. A logistics scenario and an accompanying failure taxonomy illustrate specific risks including interpretation inflation, stale authority, computational authority laundering, ineffective human oversight, and categorical overgeneralization. Revocable participation and participant-specific trust are proposed to preserve both the right to refuse and the possibility of differentiated relationship. The paper closes with a comparative research agenda connecting the proposal to classical testbeds, quantum simulation, and targeted hardware studies, specifying matched baselines, independent outcomes, and explicit overhead limits. The contribution is a conceptual integration and evaluation framework, no new experimental results are reported. It establishes a basis for examining how relational governance can remain intelligible and accountable across changing computational substrates, while leaving its empirical value open to comparison and revision.

Two Undecided Predicates: Compilation Equivalence and the Sampling Boundary in Hybrid Quantum Runtime Governance

Paweł Bański, Sergiusz Sobieski

Willis (2026) argues that a recursively self-improving system may increase its effective quantum capability without acquiring additional hardware, and that the resulting hybrid classical-quantum execution path becomes progressively harder to characterise exhaustively. The proposed response abandons exhaustive reconstruction as an assurance objective and instead requires that specified properties hold before computation is permitted to affect consequential state, with five quantum execution controls layered beneath substrate-independent constitutional invariants. This paper accepts that architecture and contests two of its load-bearing predicates. The compilation equivalence predicate. GovernanceEquivalent(C(a), C(e)) carries the entire compilation-integrity argument and is left undefined. It cannot be read as semantic equivalence: deciding circuit equivalence is QMA-complete (Janzing, Wocjan & Beth, 2005), and remains so for the shallow circuits typical of transpiled output, while semantic sameness is in any case the wrong target given what transpilation exists to do. The predicate must therefore be evaluated relative to a declared set of governance-relevant properties. That set is itself a governance object, and under recursive self-improvement it is reachable through the toolchain. An attack follows in which a compilation change justified purely on performance grounds renders a governance-relevant property unmeasurable over the executed representation, so that the permit gate continues to evaluate correctly over a test that no longer discriminates. Traceability of the executed artefact to the authorised one does not prevent this, because traceability and property preservation come apart precisely when a transformation is faithful in derivation and lossy in representation. The sampling boundary. The authorised shot count is specified as a ceiling. A ceiling bounds resource consumption; it does not bound evidentiary resolution, which varies in the same direction. Admissibility evaluated on a point estimate is therefore unsound under an adversarial or merely cost-optimising choice of sample size, and error mitigation supplies a second route that widens the uncertainty region while appearing to improve result quality. Evaluating admissibility over a confidence region rather than a point estimate is sound, imposes the necessary floor implicitly, and fails closed without requiring a separately specified minimum. An authorised sequential-sampling rule is a second sound form, subject to the condition that the stopping rule be fixed prior to sampling. Composition. The two results are not independent. The repair proposed for the second introduces a parameter that is vulnerable to the first, and the properties governing sampling can themselves be attenuated out of the property set. Sound sampling governance presupposes governed property-set membership. General form. Both attacks share a shape: an invariant is enforceable only to the extent that the instrument deciding it — its property set, tolerance, confidence level, sample size, or measurability assumption — is unreachable from inside the system it constrains. Under recursive self-improvement there is always gradient in those parameters, because they trade against latency, cost and throughput, which are the objectives the recursion optimises. No adversarial disposition is required. The paper closes by applying its own criterion reflexively. A response whose complaint is that declarations are mistaken for proof cannot end with declarations and leave the matter there. A governance requirement is structural when its violation is observable without relying on the cooperation of the governed system, and declarative when it is not; three of the four requirements proposed here are organisational by that test, and one is not. This work continues the author's earlier treatment of trajectory-level governance and the Constitutional Failure Boundary methodology (Zenodo 10.5281/zenodo.18980403) and of admissibility operators and bounded reachability in probabilistic decision systems (Zenodo 10.5281/zenodo.20057043), extended here from classical to hybrid quantum execution. No implementation is described and none should be inferred. Attribution: the counterfactual authorisation test adapted in §3.6 was proposed by R. Muro. The Layer 3 / Layer 1 redefinition formulation in §3.5 and the authorised sequential-sampling rule in §4.4 are J. M. Willis's, offered in public response to an earlier and shorter statement of these arguments.

The Unified Quantum AI Governance Stack: A Complete Architecture from Physics Foundation to Certified AI Governance Output

Ilyes Tarik MAZARI

The quantum computing field has established a rigorous five-layer architecture spanning quantum physics, qubit hardware, quantum algorithms, hybrid classical-quantum execution, and application decision output. No prior academic work has formally described the governance architecture that must sit above this stack when AI systems execute on quantum infrastructure in regulated environments. This paper presents three original contributions. First, a formal identification of the governance gap at the top of the established quantum computing stack, expressed as six concrete failure modes demonstrating why treating quantum infrastructure governance and AI system governance as independent concerns produces irreducible compliance failures. Second, the unified quantum AI governance pyramid, a fifty-layer architecture combining the established five quantum computing layers with the forty-five layers of the YIN Mazari Architecture organized into nine governance tiers. The nine tiers span physics enforcement foundation, core cryptographic enforcement, cross-domain verification, human authority, neural causal reasoning, world models, recovery and response, hardware enforcement, and three certification output layers: ACR Certification with four tiers (Platinum, Gold, Silver, Unrated), ACR-Zero Certification establishing structural impossibility of unauthorized execution, and the AQL Standard for AI Liability Quantification enabling insurers to price AI liability from cryptographic enforcement data. Third, a formal proof of bidirectional coupling between the quantum computing stack and the YIN Mazari governance architecture, demonstrating that an AI system cannot be certified compliant while the quantum infrastructure beneath it fails its cryptographic posture requirements, and that infrastructure migration cannot proceed without knowing which AI systems depend on the assets being migrated. The paper establishes unified regulatory alignment across DORA Regulation EU 2022/2554, EU AI Act Regulation EU 2024/1689, NIS2 Directive EU 2022/2555, CNSA 2.0, and HIPAA Technical Safeguards simultaneously through a single compliance attestation spanning both halves of the pyramid. This architecture is protected under 41 USPTO provisional applications comprising 4,400+ claims with priority date November 23, 2025. PCT deadline November 23, 2026. Implementation of any component requires a license from the inventor.

Observability Architecture for Quantum-Centric Supercomputing Workflows

Naoki Kanazawa, Yuto Morohoshi, Hitomi Takahashi +3 more

Quantum-centric supercomputing (QCSC) workflows often involve hybrid classical-quantum algorithms that are inherently probabilistic and executed on remote quantum hardware, making them difficult to interpret and limiting the ability to monitor runtime performance and behavior. The high cost of quantum circuit execution and large-scale high-performance computing (HPC) infrastructure further restricts the number of feasible trials, making comprehensive evaluation of execution results essential for iterative development. We propose an observability architecture tailored for QCSC workflows that decouples telemetry collection from workload execution, enabling persistent monitoring across system and algorithmic layers and retaining detailed execution data for reproducible and retrospective analysis, eliminating redundant runs. Applied to a representative workflow involving sample-based quantum diagonalization, our system reveals solver behavior across multiple iterations. This approach enhances transparency and reproducibility in QCSC environments, supporting infrastructure-aware algorithm design and systematic experimentation.

Systems & Certification Engineering, Runtime Enforcement, and Assurance for Hybrid Quantum–Classical AI Safety

Erkan YALÇINKAYA

System-level specification, a runtime assurance and monitoring framework for hybrid quantum–classical computing workloads. The document defines an operational architecture and enforcement logic for maintaining safety under measurement latency, stochastic noise, and partial observability, with emphasis on auditable, deterministic control points rather than post hoc interpretation. Contents include: A layered runtime model (instrumentation, observation/estimation, enforcement, recovery/orchestration) for hybrid quantum–classical pipelines. Decision outputs and enforcement semantics (safety violations vs. acceptable operation) and integration into a verification–safety–recovery loop. Latency management patterns, including asynchronous monitoring and retroactive veto/rollback, and conditions for maintaining safe rollback windows. Monitoring signals and estimation approaches suitable for quantum workloads (e.g., shadow-tomography-style observables) described at specification level. Implementation-specific parameters, operational thresholds, deployment artefacts, source code, environment configurations, and empirical tuning details are intentionally omitted to protect ongoing commercialisation and patent considerations. The manuscript is intended for technical review, research collaboration, and prior-art disclosure without revealing proprietary operational settings.
