Healthcare fraud is a major issue in the medical and insurance industry, leading to significant financial losses and reduced trust in healthcare systems.Fraudulent claims include false billing, unnecessary treatments, and misuse of insurance services.Traditional fraud detection methods rely on manual verification and classical machine learning techniques, which often suffer from limited accuracy, high processing time, and difficulty in handling complex datasets.With the advancement of quantum computing, Quantum Machine Learning (QML) has emerged as a powerful solution that utilizes quantum properties such as superposition and entanglement to improve computational efficiency.This project focuses on developing a healthcare claim fraud detection system using quantum techniques like Quantum Support Vector Machine (QSVM) and Variational Quantum Classifier (VQC).The system analyzes patient and claim-related data such as age, medical history, billing details, and treatment records to identify fraudulent patterns.By encoding classical data into quantum states and processing it through quantum circuits, the model improves pattern recognition and classification accuracy.The proposed system integrates classical preprocessing with quantum algorithms to achieve better performance compared to traditional models, and experimental results show higher accuracy, faster processing, and improved efficiency, demonstrating the potential of quantum computing in healthcare fraud detection.In addition, the system reduces dependency on manual verification and increases automation in the fraud detection process.It also helps in identifying hidden patterns that are difficult to detect using traditional systems.The system contributes to improving decision-making processes in insurance companies.Overall, the proposed model provides a reliable and efficient solution for modern healthcare challenges.
This paper presents a first end-to-end application of a Quantum Support Vector Machine (QSVM) algorithm for a classification problem in the financial payment industry using the IBM Safer Payments and IBM Quantum Computers via the Qiskit software stack. Based on real card payment data, a thorough comparison is performed to assess the complementary impact brought in by the current state-of-the-art Quantum Machine Learning algorithms with respect to the Classical Approach. A new method to search for best features is explored using the Quantum Support Vector Machine's feature map characteristics. The results are compared using fraud specific key performance indicators: Accuracy, Recall, and False Positive Rate, extracted from analyses based on human expertise (rule decisions), classical machine learning algorithms (Random Forest, XGBoost) and quantum-based machine learning algorithms using QSVM. In addition, a hybrid classical-quantum approach is explored by using an ensemble model that combines classical and quantum algorithms to better improve the fraud prevention decision. We found, as expected, that the results highly depend on feature selections and algorithms that are used to select them. The QSVM provides a complementary exploration of the feature space which led to an improved accuracy of the mixed quantum-classical method for fraud detection, on a drastically reduced data set to fit current state of Quantum Hardware.
Abstract: Financial fraud detection is a persistent challenge due to the dynamic, adversarial nature of fraudulent activities. This study investigates the potential of Quantum Machine Learning (QML) algorithms for pattern recognition in financial datasets characterized by high dimensionality and imbalance. Quantum Support Vector Machines (QSVM) and Variational Quantum Classifiers (VQC) were trained and tested using the Qiskit platform on a representative fraud dataset. Performance metrics were evaluated against classical benchmarks and analyzed using statistical and regression models. The findings highlight that QML offers meaningful performance enhancements, particularly in F1 score and recall, suggesting its viability for future adoption in financial surveillance systems.
