Quantum computing's potential to compromise conventional cryptography has spurred the development of quantum-secure communication methods, with Quantum Key Distribution (QKD) offering a promising solution. Researchers have simulated and analyzed prominent QKD protocols, including BB84, B92, and E91, using IBM's Qiskit platform1. This analysis aims to assess the security and feasibility of these protocols in the face of quantum computing threats. The simulation results provide valuable insights into the performance and limitations of each protocol, shedding light on their potential for securing communication against quantum attacks. As quantum computing advances, the need for quantum-secure communication methods becomes increasingly urgent, with IBM's developments narrowing the timeline for cryptographic migration. The findings of this research underscore the importance of preparing for the transition to post-quantum cryptography, making it essential for practitioners to prioritize quantum-resistant security measures. This research has significant implications for the future of secure communication, highlighting the need for swift adoption of quantum-secure protocols.
