Waves, Quantum Theory, and Retail Credit
Quantum superposition and wave-particle duality improve retail credit models by encoding loan metrics into quantum states. The authors propose a credit superposition matrix to represent overlapping borrower risk profiles. Small-scale tests on quantum processors deliver 20--30% better prediction accuracy and two- to fivefold faster performance than classical methods. Hybrid Monte Carlo and quantum amplitude estimation cuts forecasting uncertainty. Hardware constraints and pending validation remain. The study paves the way for large-scale quantum credit risk assessment.
What it examines
This paper explores how superposition and wave-particle duality principles can improve retail credit modeling. It reviews quantum computing methods to build more efficient and accurate loan risk models. By mapping financial data onto qubit states, the study aims to show potential gains in speed and predictive power.
What it concludes
Results suggest quantum computing may speed and refine credit risk predictions, enabling faster loan decisions and portfolio management. Applications include dynamic interest rates and real-time risk scoring. Challenges like hardware limits and algorithm design persist. Future work should test these models on live data and advance quantum algorithms.
