The journey to develop drugs is long, time-consuming, and costly.Most drugs take years and billions of dollars before they hit the market.Traditional computations remain useful but have inadequacies to accurately reproduce molecular interactions and predict drug efficacy.Quantum computing represents a new tool to potentially revolutionize the challenges brought about by traditional computations in that it can more quickly and accurately solve several of these problems through applying the principles of quantum mechanics.This review examines the possibility of quantum computing to transform pharmaceutical research and drug development.The aim of this review is to give the reader an all-round perspective on the use of quantum computing in drug discovery, with its contributions to molecular modeling, drug-target interaction prediction, and pharmacological property optimization.It promises something new in the application of quantum algorithms to make up for the faults of classical methods used in pharmaceutical research.This review critically synthesizes a number of relevant studies that applied quantum computing capabilities to drug design.Particular attention is brought to quantum algorithms, including but not limited to VQE (Variational Quantum Eigensolver) and QAOA (Quantum Approximate Optimization Algorithm), in determining molecular structures in silico along with the capacity to predict chemical binding affinities.Secondly, the scope of the drugs-discovery application on the various platforms such as IBM Q versus Google Sycamore were compared with current classical computational approach.The quantum computer showed a lot of promise in the simulation of complicated molecular interactions faster than the classical counterparts.A lot of studies emphasize the accuracy quantum simulations have towards the prediction of drug-target binding mechanisms, and this makes the lead optimization process more efficient.However, with scalability and hardware issues, its application in the pharmaceutical research community is still yet to be wide-scale.Quantum computing promises to accelerate the drug development process by improving the speed and accuracy of molecular modeling and drug optimization.Although the field is still in its infancy, its integration into pharmaceutical research could lead to significant reductions in development time and cost.This review underlines the transformative potential of quantum computing and suggests future research directions for overcoming the current limitations and realizing its full potential in precision medicine.
The traditional drug discovery process is slow, resource-intensive, and often unsuccessful. This is mainly because regular computers find it hard to accurately model complex molecular interactions at the quantum level. This abstract suggests that Quantum Computing (QC) could change the game. It uses the principles of superposition and entanglement to transform pharmaceutical research. QC will provide a significant increase in computing power for quantum chemistry simulations. This will help researchers model the electronic structure of molecules and their exact behavior, including protein folding, binding affinities, and off-target effects, with great accuracy and speed. Algorithms like the Variational Quantum Eigensolver (VQE) are expected to uncover insights into drug-target interactions that we cannot currently obtain. This will greatly reduce the need for costly and lengthy physical experiments. Additionally, QC can improve virtual screening and support next-generation Quantum AI for faster analysis of genomic data and better optimization of drug candidates. Though the technology is still in its early stages, using QC could notably shorten development timelines and lower costs. This will enable the discovery of more targeted and effective drugs, leading to significant progress in treating complex diseases and a new era of precise, personalized medicine. The shift will require ongoing investment in reliable quantum hardware and specialized quantum algorithms.

Materials science has historically depended on a blend of experimental methods and theoretical modelling to identify and create new materials with specific properties. Nevertheless, these processes may require considerable time and resources, and are frequently constrained by the intricacy of material systems. The rise of artificial intelligence (AI), particularly machine learning, has revolutionised materials science by offering powerful tools that accelerate the discovery, design, and characterisation of novel materials. This chapter emphasises the latest developments in AI applications in materials science for drug discovery. Artificial Intelligence is proficient at analysing intricate data, enhancing processes, and developing drug candidates, whereas quantum systems enable unparalleled molecular simulations, highly sensitive sensing, and accurate physical control. Applications in drug discovery are emphasised, encompassing molecular property prediction and molecular generation. This chapter focuses on technologies such as Nanomaterials, Biomaterials, Polymers, Metal-Organic Frameworks (MOFs), Hydrogels, and Smart Materials. This chapter emphasises the advantages of quantum technology in drug discovery: enhanced accuracy in molecular simulations, Accelerated drug screening, better comprehension of reactions, and Tailored medicine. Additionally, the challenges include: hardware limitations, the high cost of error correction, the maturity of algorithms, integration with classical methods, and issues related to cost and accessibility.
This study identifies that new drugs are inherently complicated and require a lot of resources. These initiatives require years of financial investment, and the highly potent medicines that are produced were the final consequence. This study explores the potential uses of quantum computing to enhance molecular simulations and optimize drug prospect interactions. A comparative analysis between quantum and classical methodologies can be used to make a quantitative comparison. The results showed that VQE performs 37.8% more accurately than its classical predecessors, with a mean absolute error of 0.028 Hartree. Furthermore, the 86.7% success rate of QAOA in improving molecular structures would signify a significant performance improvement compared to traditional optimization methods. For VQE on quantum simulators, the average computing time is 8.4 minutes per molecule, which is 42.9% faster than for classical methods. Based on their better computational efficiency and ability to improve the accuracy of molecular property predictions, quantum algorithms appear to be a very promising tool for speeding up the drug discovery process. The results show that quantum machine learning has the potential to transform pharmaceutical research by advancing the development of new treatments.
However, accurately simulating molecular interactions constitutes the central, but open question of computer chemistry. This is a core task for efforts in drug development, catalyst design, and materials science. Most classical algorithms perform well on smaller systems, but incumbent exponential scaling penalties are unavoidable as models grow larger and more complex to describe quantum behaviour. An entirely new paradigm for this problem is now introduced by quantum computing: superposition and entanglement resources natively encode quantum states and model their electronic structures. The paper will thus take a high-level view of the leading quantum algorithms, with particular regard to those called Variational Quantum Eigensolver (VQE) and Quantum Phase Estimation (QPE), while evaluating their performance on today's Noisy Intermediate Scale Quantum (NISQ) devices. Next will follow discussions on algorithm design and current hardware capabilities, before which open challenges on scalability, error mitigation, and algorithm design will be outlined. Emphasis shall also be placed on the ethics and accessibility issues as well as the timelines with which quantum computing might gain a practical advantage. Linking together the recent advances and limitations, this paper posits how quantum computer implementation may change the face of chemical modelling and scientific discovery.
