Abstract

The exorbitant costs, protracted timelines, and elevated attrition rates associated with traditional drug-discovery pipelines underscore the pressing necessity for computational frameworks that can elucidate biomolecular interactions with quantum-level precision and practical scalability. This study introduces a Hybrid Quantum Classical (HQC) framework that combines quantum variational algorithms, classical molecular dynamics, and quantum-assisted machine-learning optimization into a single drug-screening workflow. It builds on the basic idea of Quantum Molecular Simulation (QMS). In the suggested design, quantum processors are used to selectively fix high-fidelity electronic interactions in reactive binding sites, while classical engines model the large-scale conformational dynamics of biomolecular environments. An adaptive quantum-machine-learning layer speeds up convergence even more by learning how structure and energy are related from quantum-refined descriptors. Benchmark tests against oncogenic targets like EGFR, BCR-ABL1, and p53 show that our method is up to 27% more accurate at converging binding energy and takes 4.3 times less time to compute than standard density-functional-theory and standalone QMS methods. The HQC framework makes quantum drug simulation possible for real-world drug discovery by reducing the limitations of current quantum hardware while keeping electronic-scale accuracy. This study demonstrates that hybrid quantum-classical modeling is a scalable and hardware-compatible approach for advancing next-generation computational drug design and precision therapeutics.
