The study evaluates quantum machine learning (QML) models for network intrusion detection against well-tuned classical baselines across four standard datasets, using a leakage-controlled protocol and noise simulation. It introduces a quantum-attribution audit to determine whether any performance gains are truly due to quantum effects. While most tuned classical models match or surpass QML, two quantum approaches— a quantum-kernel SVM and a small hybrid circuit—show statistically significant advantages on specific metrics and tasks.
The paper introduces Hybrid Quantum Root Cause Analysis (HQ‑RCA), a workflow that applies a hybrid Quantum Graph Neural Network (QGNN) to banking IT operations. HQ‑RCA replaces the classification head of the classical DynEdge GNN with a Variational Quantum Circuit, achieving comparable F1 performance to the strongest classical baseline while simplifying the quantum readout to a single Pauli‑Z expectation. Experiments on 13 k anonymised alarm clusters from a major European bank demonstrate that the quantum component can be executed on NISQ hardware without error mitigation, using a gradient‑free grid scan for optimisation.
