This manuscript introduces a novel Quantum-Enhanced Cyber Security Framework for E-commerce platforms, designed to address the emerging challenges posed by quantum computing to cyber security. The framework integrates quantum computing principles into key aspects of cyber security, offering a robust solution against both classical and quantum threats. Central to the proposed approach are three innovative components: quantum key distribution, a Quantum-Resilient Cyber Trust Verification Protocol, and a Distributed Quantum Ledger for Cyber Secure E-commerce. Simulations validate that the proposed approach significantly outperforms traditional security methods in key generation rate and error reduction, demonstrating its efficacy in a quantum-threatened cyber domain.
