CREDIT CARD FRAUD DETECTION USING QUANTUM MACHINE LEARNING: A HYBRID CLASSICAL-QUANTUM APPROACH

With the rapid growth of digital financial transactions, credit card fraud detection has become a critical challenge in the banking and finance sector. Traditional rule-based systems and classical machine learning (ML) models often struggle to detect complex and evolving fraud patterns, especially in highly imbalanced datasets. This paper proposes a novel hybrid approach to credit card fraud detection using Quantum Machine Learning (QML) techniques combined with classical methods. The system app
