This study introduces a hybrid quantum-classical framework designed to mitigate electromagnetic interference (EMI) in network cables, with a focus on optimizing signal integrity through advanced computational techniques. 1 By integrating the Quantum Approximate Optimization Algorithm (QAOA) with custom-engineered materials, we effectively reduce distortions arising from magnetic field coupling. The system is modeled using Maxwell's equations and rigorously validated through electromagnetic simulations and circuit-level analyses. Nonlinear phenomena, including permeability saturation and frequency-dependent losses, are quantified using both analytical and numerical models. Results demonstrate that QAOA achieves a significant reduction in bit error rate (BER), surpassing classical paper swarm optimization (PSO) by an order of magnitude and outperforming conventional methods by two orders. Notably, the QAOA framework converges in just 50 iterations—halving the computational effort required by PSO— while maintaining a probe power of 5 W. The implemented engineered materials contribute to a 30 50% reduction in signal distortion, showcasing substantial improvements in noise suppression. Although current quantum hardware limitations restrict immediate scalability, the inherent efficiency of QAOA in combinatorial optimization positions it as a transformative tool for critical applications demanding ultra-reliable communication, such as defense and medical systems. A comparative analysis highlights the limitations of classical methodologies in large-scale, high-interference environments. This research advocates for the integration of quantum-inspired strategies into industry standards and outlines pathways for developing robust communication infrastructures.

Optimization problems are widely encountered in real-world domains such as energy systems, financial markets, transportation networks, supply chain logistics, manufacturing processes, and e-commerce platforms. Traditional classical computing methods often struggle to solve large combinatorial optimization problems due to the exponential growth of the solution space. Quantum computing has emerged as a promising approach to address these challenges by leveraging quantum mechanical principles such as superposition and entanglement. However, current quantum hardware is limited by noise, restricted qubit availability, and scalability issues, making fully quantum solutions impractical for large-scale applications. To overcome these limitations, this research proposes a hybrid quantum–classical supercomputing framework for solving complex optimization problems across multiple domains. The framework integrates classical data processing and optimization techniques with quantum-inspired algorithms, specifically the Quantum Approximate Optimization Algorithm (QAOA), to efficiently explore large solution spaces. Real-world datasets from energy systems, supply chain logistics, financial markets, transportation networks, manufacturing processes, and e-commerce platforms are used for experimental evaluation. The results demonstrate that the hybrid optimization approach can generate higher-quality solutions and improved optimization accuracy compared to traditional classical methods. These findings highlight the potential of hybrid quantum–classical systems as an effective and scalable solution for solving complex optimization problems in modern computational applications.

This paper is a comparison between classical and quantum inspired methods for solving the max-flow problem, which is commonly a foundational challenge in optimization and graph theory. This study will investigate the feasibility and performance of applying the Quantum Approximate Optimization Algorithm (QAOA) and other hybrid quantum-classical approaches to address the max-flow problem. This paper starts with comparing quantum approaches with well-established classical methods such as the Ford-Fulkerson and Edmonds-Karp.The main aim of this work is to asses how close quantum-inspired formulations can get to classical approaches in terms of their flow value as well as their runtime. Implementations are developed using the Qiskit framework on simulated quantum backends and compared against classical baselines across synthetic graph instances of varying sizes and densities. Experimentally, it can be seen that quantum approaches implemented using the QAOA technique managed to attain flow solutions comparable to classical ones, demonstrating similar accuracy, and in certain very dense graph configurations, competitive runtime performance due to parallelization in state-vector computing.These findings suggest that although current quantum-inspired approaches may not yet surpass classical algorithms in efficiency, but they can replicate their outcomes with reasonable fidelity. This provides an important validation of their applicability to combinatorial optimization. This study also lays groundwork for future research to explore hardware-level implementations, scalability enhancements, and also hybrid integration strategies for quantum optimization in network flow problems.
Quantum computing, as an emerging computational paradigm, has garnered significant attention due to its potential advantages in combinatorial optimization and quantum chemistry problems. A hybrid quantum-classical model that integrates VQE and QAOA for efficient task assignment and path optimization is suggested. However, constrained by hardware noise, qubit limitations and parameter optimization bottlenecks, these algorithms still face challenges such as convergence instability, gradient vanishing and low ground state probability in large-scale problems. This paper proposes a hybrid optimization framework that integrates improved VQE and QAOA, introducing adaptive parameter initialization and multi-level parameter scheduling mechanisms into VQE. In contrast, QAOA combines an improved classical optimizer and parameter perturbation strategy, thereby enhancing the algorithm’s global convergence capability in the search space. Experiments on combined optimization examples with 6, 9, 10 and 12 qubits demonstrate that this method can significantly improve ground state probability and convergence stability under limited hardware conditions. The results validate the effectiveness of the proposed framework in complex scheduling and resource allocation tasks, showcasing its potential applications in the practical implementation of quantum optimization.
