On a synthetic financial dataset, one-class SVMs using projected quantum kernels achieved higher mean F1 scores than a classical rbf-kernel baseline at every tested anomaly ratio, both in simulation and on quantum hardware, though the statistical evidence is weak.

Unsupervised Quantum Anomaly Detection on Noisy Quantum Processors
On a synthetic financial dataset, one-class SVMs using projected quantum kernels achieved higher mean F1 scores than a classical rbf-kernel baseline at every tested anomaly ratio, both in simulation and on quantum hardware, though the statistical evidence is weak.
