Applications of Quantum Computing in Drug Development

Review Article

Abstract

Drug development remains a complex, time-intensive, and costly process, with high failure rates in clinical trials. The advent of quantum computing presents promising opportunities to transform pharmaceutical research and development through enhanced molecular simulations and structure-based drug design. Quantum computing uses quantum mechanical phenomena like superposition and entanglement to process complex molecular interactions more efficiently than classical computers. The integration of quantum computing with machine learning algorithms has enabled more accurate predictions of drug-target interactions and improved virtual screening of compound libraries. Applications include structure-based drug design, molecular docking, lead optimization, and drug repurposing. Notable progress has been made through collaborations between pharmaceutical companies and quantum computing firms, demonstrating practical implementations in drug discovery workflows. However, several challenges persist, including hardware limitations, algorithmic maturity, skilled workforce gaps, and regulatory considerations. The combination of quantum computing with classical computing and machine learning approaches offers a hybrid framework that maximizes the strengths of each technology. As quantum computing technology advances, it is positioned to significantly impact pharmaceutical research and development, potentially reducing development timelines and improving success rates in drug discovery. This review explains the principles, current applications, integration, and limitations of quantum computing in drug development
