Abstract: Autonomous cyber-physical networks increasingly combine distributed sensing, edge intelligence, networked control, and safety-critical actuation, yet their reliability is constrained by correlated cyber faults, communication loss, model drift, hardware degradation, and the fragility of emerging quantum resources. This paper develops a fault-tolerant distributed quantum-intelligence architecture that couples photonic circuit emulation, quantum error-aware computation, AI-augmented control, distributed consensus, and deterministic safety fallback. The purpose is to formalize how heterogeneous quantum, photonic, AI, and control subsystems can jointly preserve mission-level stability when individual components fail or become uncertain. The study adopts a model-based systems methodology, synthesizes the supplied literature on fault-tolerant photonic quantum computing, distributed autonomous control, cyber-physical resilience, AI-native edge systems, and quantum-assisted optimization, and formulates a multi-layer state-space and reliability model. A composite Fault-Tolerant Quantum Intelligence Resilience Index (FTQIRI) integrates quantum reliability, photonic emulation fidelity, AI robustness, network resilience, closed-loop stability, and cyber assurance. An illustrative 0–10 numerical model yields an integrated score of 8.49 for the proposed architecture versus 6.34 for a conventional hybrid baseline, indicating the expected value of cross-layer redundancy and adaptive orchestration rather than empirical superiority. The paper further specifies an invention-oriented architecture, independent system and method claim drafts, and dependent claim concepts around digital-twin emulation, syndrome-informed control, consensus-based failover, cryptographic verification, and safety envelopes. The principal contribution is a unified mathematical and engineering framework that treats quantum fault tolerance and cyber-physical fault tolerance as coupled control problems, thereby connecting photonic quantum hardware, distributed intelligence, and autonomous network safety within one verifiable decision loop.

Abstract: Quantum signal processing (QSP) provides a mathematically economical mechanism for transforming the spectral information of a block-encoded operator through carefully phased single-qubit rotations. Photonic quantum computing, meanwhile, offers high-bandwidth operation, network compatibility and substantial room-temperature functionality, yet remains constrained by optical loss, probabilistic state preparation, finite squeezing, detector imperfections and the resource overhead of logical error correction. This paper develops an integrated analytical framework that connects QSP polynomial synthesis to fault-tolerant photonic execution and to a broader construct termed quantum-enhanced scientific intelligence: the reliable extraction of predictive, explanatory and decision-relevant knowledge from complex scientific operators and data. The study adopts a theory-building and model-based research design. It combines block encoding, QSP and quantum singular-value transformation with open-system dynamics, logical-error modelling, constrained multi-objective optimization and risk-adjusted outcome scoring. The proposed QSP-FTSI framework treats algorithmic approximation error, photonic component quality, decoder performance, logical reliability, resource intensity, uncertainty calibration and scientific utility as coupled rather than independent variables. An illustrative normalized model yields a baseline benefit index of 7.942, a composite risk index of 2.640 and a risk-adjusted score of 6.358 on a ten-point scale; an improved low-loss, high-QEC scenario reaches 7.858, whereas a stressed configuration falls to 3.754. These values are demonstrations, not experimental findings. The principal contribution is a publication-ready mathematical architecture for evaluating when QSP-enabled photonic systems can support scientifically meaningful simulation, inverse modelling, spectral filtering and inference under explicit fault-tolerance and reproducibility constraints. The framework also identifies measurable pathways for experimental validation, hardware–algorithm co-design and responsible scientific deployment.

The growing scale and complexity of photonic quantum systems demand a transition from manual, heuristic control toward intelligent, autonomous operational frameworks. Quantum Artificial Intelligence (QAI) integrates machine learning, quantum-enhanced optimization, and real-time feedback to address key challenges in the calibration, stabilization, and scaling of photonic quantum technologies. Unlike conventional machine-learning-assisted quantum control and self-driving laboratory approaches that rely primarily on classical intelligence, the proposed QAI paradigm establishes a tighter integration between artificial intelligence and quantum hardware. Parameterized quantum circuits executed directly on the photonic processor participate in the agent’s decision-making process, while the same framework supports both real-time control tasks. QAI combines variational quantum neural networks, meta-reinforcement learning, multi-agent control architectures, and quantum optimization methods, such as the Quantum Approximate Optimization Algorithm, to enable adaptive calibration, error mitigation, and high-dimensional optimization in programmable photonic platforms. While this perspective focuses on real-time control and calibration, we also outline a conceptual pathway toward autonomous generative inverse design. To guide future development, we propose a three-stage roadmap that progresses from open-source hybrid quantum–classical control tools to fully autonomous laboratories capable of closed-loop self-optimization and experiment design. Experimental platforms include programmable silicon photonic circuits and lithium-niobate interferometers, where thermal drift, fabrication variability, and crosstalk require intelligent adaptation. Beyond quantum optics, the QAI framework has broader implications for quantum sensing, secure communications, and photonic computing. By introducing a unified QAI framework and a structured classification of Quantum Autonomy Levels (QALs), this work provides a roadmap toward autonomous quantum-optics laboratories and photonic quantum technologies.
The rapid evolution of communication networks, driven by the expansion of heterogeneous environments such as 6G, Internet of Things (IoT), and edge computing, has exposed a critical research gap in the lack of unified frameworks that jointly address intelligent network control and quantum-resilient security. Existing networking protocols were originally designed under static configurations and classical security assumptions, making them increasingly inadequate for dynamic, large-scale, and intelligent infrastructures exposed to quantum-enabled threats. At the same time, the emergence of Quantum Computing (QC) introduces severe security risks, as widely used cryptographic mechanisms supporting protocols such as Transport Layer Security (TLS) and Internet Protocol Security (IPsec) become vulnerable to quantum attacks. This paper presents a structured survey based on a systematic classification of recent literature across AI-enabled networking, Post-Quantum Cryptography (PQC), Quantum Key Distribution (QKD), and protocol-level integration approaches. The review categorizes existing works into AI-driven network optimization, quantum-resilient security mechanisms, and hybrid AI–QRC architectural frameworks, enabling a unified comparison of design strategies and deployment models. Furthermore, this survey analyzes how Artificial Intelligence (AI) techniques enable autonomous network operations while Quantum-Resilient Cryptography (QRC) approaches provide post-quantum security guarantees, highlighting their complementary roles in next-generation network design. The study further synthesizes key findings for a tightly coupled AI–QRC co-design, which remains an open challenge due to mismatched assumptions in control latency, cryptographic overhead, and protocol adaptability. Additionally, this review emphasizes the need for integrated frameworks that combine intelligence and quantum security to develop adaptive, scalable, and resilient network protocols for the post-quantum era.
Abstract: The accelerating convergence of artificial intelligence, quantum and quantum-inspired computation, digital twins, advanced sensing, secure connectivity and operations research creates a new design space for transforming economic systems, industrial production and service delivery. Yet the literature remains fragmented across manufacturing, infrastructure, networks, public administration and domain-specific optimization. This paper develops a unified Quantum-AI Innovation and Optimization for Transformation (QAIOT) framework that links data intelligence, quantum-enhanced search, multi-objective optimization, sectoral constraints, governance and measurable transformation outcomes. The study adopts a model-based analytical design and synthesizes only the references supplied in the source corpus. A mathematical formulation combines state-space dynamics, matrix coupling, constrained multi-objective optimization, Bayesian risk adjustment and a composite transformation index. The numerical demonstration uses normalized 0–10 values to show how productivity, resilience, sustainability, service quality, innovation capacity and institutional trust can be integrated without presenting the numerical outputs as empirical findings. The analysis indicates that the greatest conceptual value of Quantum-AI is not a universal computational speedup, but selective acceleration of difficult search, scheduling, allocation, network and simulation problems embedded within AI-driven decision pipelines. Sectoral benefits depend on data quality, interoperability, compute economics, cybersecurity, governance and human oversight. The paper contributes an extensible cross-sector architecture, a prior-art matrix, a transparent numerical scoring model and an implementation roadmap for testing Quantum-AI systems in manufacturing, energy, finance, logistics, healthcare, public services and digital service ecosystems. The framework is intended to support rigorous empirical validation and responsible deployment rather than unsupported claims of quantum advantage.

Abstract: This study investigates quantum-accelerated intelligence as a national capability that integrates hybrid artificial intelligence with quantum and quantum-inspired optimisation. In many public infrastructures, predictive models deliver situational awareness, but operational value is constrained by hard, time-critical optimisation tasks such as scheduling, routing, and resource allocation under safety and equity constraints. Quantum optimisation is treated as a modular accelerator for selected subproblems rather than as a universal replacement for classical planning. A cross-layer reference architecture is specified to connect interoperable data products, trustworthy model operations, and optimisation services across cloud-to-edge deployments. To support transparent benchmarking, a Quantum-Accelerated Intelligence Readiness Index (QAIRI) is introduced using real, open indicators from the World Bank World Development Indicators (WDI). The index is designed to diagnose ecosystem bottlenecks across innovation capacity, secure digital infrastructure, sustainability constraints, and absorption potential. Results show substantial dispersion in readiness across major economies, with stronger readiness associated with balanced progress across research capacity, digital trust infrastructure, and renewable integration. The findings motivate a cautious-acceleration roadmap: mission pilots with measurable baselines, procurement rules that require evidence and auditability, and policy-as-code guardrails that reduce operational risk while enabling public value at scale. Keywords: quantum optimisation; hybrid AI; national infrastructure; trustworthy AI; digital twins; TwinOps; green compute; governance; cloud-to-edge; resilience. ______________________________________________________________________________
Abstract: This study investigates a topological quantum error-correction framework for scalable photonic quantum-computing architectures in which fusion-based entangling primitives are combined with tensor-network optimization. The central problem addressed is the gap between high-fidelity photonic components and the stringent logical-error rates required for fault-tolerant quantum computation. Photonic platforms offer room-temperature operation, manufacturable silicon-photonic process flows, high-bandwidth optical interconnects and natural compatibility with measurement-based computation; however, photon loss, probabilistic fusion and decoder latency impose architectural constraints that cannot be resolved by hardware fidelity alone. The proposed framework therefore treats hardware metrics, code geometry and decoding as a coupled optimization problem rather than as separate engineering layers. The manuscript develops a mathematically grounded model of surface-code and cluster-state error correction under photonic loss and fusion noise, then evaluates tensor-network contraction as a decoder and resource-allocation method. The data section explicitly uses published real-data-based benchmark inputs from contemporary photonic and quantum-error-correction literature, supplemented by transparent, domain-plausible projections where complete open photonic logical-QEC datasets are not yet available. Results show that tensor-network optimization improves the logical-error index relative to matching-based baselines in the modelled photonic regime, while the feasibility boundary remains dominated by loss, fusion infidelity and real-time decoding latency. The contribution is a reproducible evaluation framework that links topological protection, photonic architecture constraints and decoder design for future scalable fault-tolerant systems.
