Quantum Machine Learning for UAV Swarm Intrusion Detection
This study rigorously benchmarks Quantum Machine Learning (QML) approaches for intrusion detection in UAV swarms. Leveraging a 120k-flow simulation corpus across five attack types, the research evaluates quantum kernels, variational quantum neural networks (QNNs), and hybrid quantum-trained neural networks (QT-NNs) against strong classical baselines. Key findings reveal that quantum kernels and QT-NNs excel in low-data, nonlinear regimes, while deeper QNNs face trainability issues. Hybrid QNNs, combining modest quantum expressivity with lightweight classical regularization, achieve the best performance, suggesting a practical path to quantum advantage in network security.
Executive Impact
Intrusion detection in Unmanned Aerial Vehicle (UAV) swarms is complex due to high mobility, non-stationary traffic, severe class imbalance, and resource constraints. Traditional IDS often require extensive feature engineering or large datasets to capture complex attack patterns, making them less suitable for dynamic, resource-limited UAV environments. This necessitates lightweight, data-driven solutions capable of robust performance under challenging conditions.

Attack Types Covered
This research explores Quantum Machine Learning (QML) as a promising solution for UAV swarm intrusion detection. QML methods—quantum kernels, variational quantum neural networks (QNNs), and hybrid quantum-trained neural networks (QT-NNs)—are benchmarked against classical baselines using an 8-feature flow representation from a 120k-flow simulation corpus. The goal is to identify QML approaches that offer superior expressivity, representation power, and scalability, potentially enhancing generalization and robustness in security-critical, resource-constrained UAV swarm settings.

Quantum kernel methods, an extension of classical kernel methods, use quantum feature maps to embed data into high-dimensional Hilbert spaces. They leverage quantum measurements to compute inner products, capturing complex relationships that are hard to replicate classically. While powerful for nonlinear regimes, their fixed kernels can limit adaptability.

Performance Characteristics
Quantum kernels achieved a solid F1-score of 0.956 and accuracy of 0.926, outperforming classical SVMs slightly. They reduce variance but inherit the expressivity ceiling of classical kernels, indicating strong performance in low-data, nonlinear regimes but with limitations in adapting to highly dynamic data distributions.
QNNs are parameterized quantum models mapping classical inputs to measurement statistics. They prepare quantum states whose expectation values serve as inference statistics. While theoretically expressive, deeper QNNs can suffer from barren plateaus (exponentially vanishing gradients), making trainability challenging on noisy, shallow hardware.
Trainability and Sensitivity Trade-offs
Pure variational QNNs often achieved very high sensitivities (up to 0.999 for QNN-6L) but suffered from poor specificity and lower overall accuracy (as low as 0.793 for QNN-8L). This is due to barren plateaus in deeper circuits, leading to difficulties in training and imbalanced performance across classes. Shallow QNNs mitigate these issues but have limited expressivity.

Final Prediction ŷ
Quantum-Trained Neural Networks (QT-NNs) integrate a parameterized quantum circuit to generate or adapt weights for a classical neural network. This hybrid approach leverages quantum entanglement to induce structured priors and stochasticity over classical model parameters, offering an efficient balance between quantum expressivity and classical inference maturity.
| Model | Accuracy | F1-Score | Qubits | Classical Params | Quantum Params |
|---|---|---|---|---|---|
| HybridQNN-8L (Best) | 0.948 | 0.967 | 8 | 18 | 64 |
| QT-NN (8, 2) | 0.939 | 0.960 | 8 | 162* | 16 |
| SVM (Classical Baseline) | 0.924 | 0.951 | N/A | N/A | N/A |
| QNN-8L (Deep QNN) | 0.793 | 0.883 | 8 | 0 | 64 |
*Classical parameters in QT-NN are not trained directly. They are generated by the quantum module controlled by the trainable quantum parameters.
Bridging the Gap: Optimal Performance
Hybrid QNNs, particularly the HybridQNN-8L model, achieved the best overall performance with an accuracy of 0.948 and F1-score of 0.967. This architecture effectively allocates correlation extraction to a shallow, hardware-efficient quantum circuit and calibration to a miniature classical head. This approach maximizes accuracy and resource efficiency, representing the most practical path to quantum advantage under current hardware constraints in UAV swarm intrusion detection.
