The drug discovery process is a time-consuming and quite expensive process. The predictive models of machine learning algorithms have been used efficiently for years in various stages of the drug discovery pipeline. The complexity of these algorithms increases as the size of the molecule increases, adding a single atom to a molecule increases the number of possible combinations. Quantum computers with quantum supremacy can play an important role in complex calculations. Combining the two technologies in practice is a complex endeavor that requires diverse, interdisciplinary teams of scientists working together to be able to integrate the two technologies with the goal of reducing cost and time in drug discovery.

The recent pandemic outbreak has posed significant challenges for medical research, particularly in drug discovery. Machine learning (ML) has become increasingly prevalent in various stages of drug discovery, aiming to support the advancement of new drug research while reducing time and cost investments. Furthermore, the emergence of quantum computing and quantum machine learning (QML) represents a significant advancement in this field, offering the ability to tackle the complex processes involved in drug discovery. This review provides a comprehensive perspective, comparing advanced QML to classical ML in drug discovery applications including drug design, virtual screening, and absorption, distribution, metabolism, excretion and toxicity (ADMET) prediction.

Drug discovery and development is a highly complex and costly endeavor, typically requiring over a decade and substantial financial investment to bring a new drug to market. Traditional computer-aided drug design (CADD) has made significant progress in accelerating this process, but the development of quantum computing offers potential due to its unique capabilities. This paper discusses the integration of quantum computing into drug discovery and development, focusing on how quantum technologies might accelerate and enhance various stages of the drug development cycle. Specifically, we explore the application of quantum computing in addressing challenges related to drug discovery, such as molecular simulation and the prediction of drug-target interactions, as well as the optimization of clinical trial outcomes. By leveraging the inherent capabilities of quantum computing, we might be able to reduce the time and cost associated with bringing new drugs to market, ultimately benefiting public health.
The drug discovery process is a rigorous and time-consuming endeavor, typically requiring several years of extensive research and development. Although classical machine learning (ML) has proven successful in this field, its computational demands in terms of speed and resources are significant. In recent years, researchers have sought to explore the potential benefits of quantum computing (QC) in the context of ML, leading to the emergence of Quantum Machine Learning (QML) as a distinct research field. The objective of the current study is twofold: first, to present a review of the proposed QML algorithms for application in the drug discovery pipeline, and second, to compare QML algorithms with their classical and hybrid counterparts in terms of their efficiency. A query-based search of various databases took place, and five different categories of algorithms were identified in which QML was implemented. The majority of QML applications in drug discovery are primarily focused on the initial stages of the drug discovery pipeline, particularly with regard to the identification of novel drug-like molecules. Comparison results revealed that QML algorithms are strong rivals against the classical ones and a hybrid solution is the recommended approach at present.
The drug discovery process necessitates a significant investment of time and resources. Typically, over a decade and billions of dollars are required to bring a single drug to market. However, quantum computing may provide a solution to these challenges. It not only has the potential to streamline drug discovery but also to enhance the quality and accuracy of the results. This chapter explores the innovative amalgamation of quantum computing and pharmaceutical research. Traditional drug discovery methods, due to their time-consuming and costly nature, face numerous obstacles. Quantum computing, armed with its extraordinary computational power, could surmount these hurdles by providing efficient and precise simulations of drug molecules. This could, in turn, expedite the discovery of effective drug candidates. The chapter delves into the fundamentals of quantum computing, its application in drug discovery, and specific techniques relevant to this field. It also presents case studies of successful applications and discusses prospects, taking current limitations into account. A particularly exciting development in this field is quantum machine learning, a fusion of quantum mechanics and machine learning. This synergy could accelerate scientific advances by offering robust predictive modeling for drug discovery. Consequently, this chapter provides an in-depth exploration of a potential future in which quantum technology, artificial intelligence, and robotics are fully integrated. Such integration could revolutionize drug discovery, heralding a new era in health care and reshaping the boundaries of medical science and therapeutic development.
