Implementation Framework of Quantum Neural Networks for Wireless Communication Applications

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.
