This paper delves into the realm of quantum computing and its potential to revolutionize data encryption methodologies. Leveraging IBM's Qiskit tool, we investigate encryption approaches aimed at bolstering data security. Commencing with a foundational elucidation of quantum computing and its pivotal role in encryption, we subsequently conduct a comparative analysis between classical binary encryption and quantum encryption methodologies. This analysis includes a practical demonstration of quantum encryption implementation utilizing Qiskit, underscoring the robustness and heightened security offered by quantum-based encryption techniques. Throughout this exploration, we address pertinent challenges encountered in the field, such as the limitations inherent in existing quantum hardware, while also outlining prospective directions for advancement. By the conclusion of this paper, readers will discern the profound implications of quantum computing in shaping the future landscape of encryption technology.
