While quantum computing is already being employed in different domains to solve large scale and highly complex optimization problems, the wireless communications community has only recently begun exploring the potential of Quantum Machine Learning (QML). This paper provides a reference design approach that allows the wireless community to effectively leverage QML in optimizing their own wireless communications networks. Such an approach will become increasingly valuable as quantum computing matures and conventional computing methods reach their practical limits due to the high dimensionality of optimization problems. We present a detailed methodology enabling wireless communications practitioners to construct their own Quantum Neural Networks (QNN) implementations and benchmark their performance against conventional techniques. Optimization strategies for wireless communication channels using QNNs are explored. The resulting framework provides a generalizable, easy-to-adopt methodology for integrating QML into wireless networks, requiring minimal prior knowledge of quantum computing.

Quantum computing harnesses quantum mechanics principles like superposition and entanglement to process information using qubits, which can represent multiple states simultaneously unlike classical bits. This enables exponential speedups for complex problems such as optimization, cryptography, and simulations that challenge classical computers. Conventional Quantum Neural Network (QNN) frameworks for wireless communications face significant emulation constraints, including exponential resource scaling, barren plateaus, and hardware noise limitations that hinder practical deployment. This paper reframes the existing QNN architecture—featuring variational quantum circuits trained on priority-based CSMA/CA simulation data—as a baseline system, highlighting its emulation-bound performance comparable to traditional neural networks via Euclidean/cosine similarity benchmarking. Key limitations include qubit/layer scaling issues, prolonged training with small batches, and susceptibility to decoherence, restricting scalability for 6G complexities. The proposed advancement transitions to fault-tolerant quantum hardware via Torch Quantum-Qiskit, incorporating distributed QNNs and error mitigation for MAC/physical layer optimizations like MIMO beamforming, channel estimation, interference mitigation, and access control. Benefits encompass exponential computational advantages, enhanced reliability in high-dimensional environments, and seamless edge-cloud integration, enabling superior efficiency over classical methods in future networks. This generalized methodology empowers wireless practitioners with minimal quantum expertise to achieve transformative network performance.

Quantum Machine Learning (QML) has emerged as a transformative paradigm that integrates the computational advantages of quantum computing with the adaptive intelligence of machine learning to solve complex optimization problems in smart computing systems. Traditional optimization techniques often struggle with high-dimensional search spaces, combinatorial complexity, computational overhead, and scalability limitations in applications such as intelligent transportation, healthcare analytics, smart manufacturing, cybersecurity, cloud computing, and Internet of Things (IoT) infrastructures. QML approaches exploit quantum superposition, entanglement, and quantum parallelism to accelerate optimization tasks and enhance predictive performance beyond classical machine learning capabilities. This research proposes a hybrid Quantum Machine Learning optimization framework that combines Variational Quantum Circuits (VQCs), Quantum Neural Networks (QNNs), and classical deep learning models to address resource allocation, task scheduling, energy optimization, and intelligent decision-making in smart computing environments. The proposed framework integrates quantum-enhanced feature extraction, adaptive optimization layers, and reinforcement-based learning mechanisms to improve convergence speed and computational efficiency. Experimental analysis is performed using benchmark optimization datasets and simulated quantum environments to evaluate accuracy, execution time, energy efficiency, and scalability. Comparative results demonstrate that the proposed QML-based framework achieves superior optimization accuracy, reduced computational latency, and improved resource utilization when compared with traditional machine learning and classical metaheuristic optimization methods. Furthermore, the study highlights the practical significance of hybrid quantum-classical architectures in next-generation intelligent systems where large-scale optimization and real-time decision support are critical. The findings suggest that QML can significantly contribute to the advancement of sustainable, adaptive, and high-performance smart computing ecosystems while opening new directions for future quantum-aware intelligent infrastructures.
This study exploits a quantum neural network (QNN) for resource allocation in wireless communications. A QNN is presented to reduce time complexity while still maintaining performance. Moreover, a reinforcement-learning- inspired QNN (RL-QNN) is presented to improve the perfor- mance. Quantum circuit design of the QNN is presented to ensure the practical implementation in noisy intermediate-scale quantum (NISQ) computers. For the QNN, the complexity and the number of required qubits are analyzed as well. As a particular use case, the QNN is utilized for user grouping in non-orthogonal multiple access. The results reveal that the QNN schemes have lower complexities and similar performance in terms of the achievable sum rate when compared with that of the classical neural network.
