Workshop Description
Covers quantum anomaly detection, quantum machine learning for transaction classification, and quantum graph analysis for AML/KYC compliance. Participants build a quantum fraud detection pipeline, benchmark it against classical baselines, and assess where quantum methods add genuine value in current and near-term fraud analytics workflows.
Financial fraud detection faces a triple challenge: transaction volumes growing faster than classical processing capacity, adversarial actors continuously adapting to detection models, and false positive rates that consume investigation resources. Quantum approaches address different parts of this problem. Quantum anomaly detection algorithms can identify outlier patterns in transaction data using quantum feature spaces that capture correlations classical models miss. Quantum walk algorithms offer polynomial speedups for graph analysis problems central to AML, including entity resolution and beneficial ownership chains. Published proof-of-concept work from the HSBC/IBM quantum fraud detection pilot (2023), the Credit Agricole/Pasqal collaboration on quantum ML for fraud (2024), and academic groups shows measurable improvements in precision on synthetic fraud datasets. Production deployment requires hybrid architectures where quantum handles batch scoring of high-risk segments while classical systems manage real-time throughput.
What participants cover
- Quantum anomaly detection: quantum one-class SVM (Rebentrost et al.) and quantum clustering algorithms applied to transaction outlier identification in high-dimensional feature spaces
- Variational quantum classifiers for fraud/not-fraud scoring, including quantum kernel methods for feature extraction from transaction metadata and strategies for extreme class imbalance
- Hands-on pipeline construction: encoding transaction features, training on labelled fraud data, benchmarking precision and recall against classical random forest and XGBoost
- Quantum walk algorithms for AML graph analysis: entity resolution, beneficial ownership chain detection, and network traversal with polynomial speedup over classical methods
- Hybrid integration architecture: batch quantum scoring alongside real-time classical systems, with honest assessment of current hardware constraints and maturity level
- Published benchmark evidence from the HSBC/IBM pilot and Credit Agricole/Pasqal proof-of-concept, and what these results mean for false positive reduction and production readiness
