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.
arXiv:2602. 16018v2 Announce Type: replace-cross Abstract: Graph neural networks (GNNs) are a powerful framework for learning representations from graph-structured data, but their direct implementation on near-term quantum hardware remains challenging due to circuit depth, multi-qubit interactions, and qubit scalability constraints.
