Quantum computing is emerging as a transformative approach in bioinformatics and quantum chemistry, addressing fundamental computational limitations of classical methods in molecular science. Many biological and chemical systems are inherently governed by quantum mechanics, making accurate simulation with classical algorithms computationally expensive or infeasible. This review examines how quantum computing, particularly in the Noisy Intermediate-Scale Quantum (NISQ) era, is advancing molecular modeling, reaction dynamics, and bioinformatics applications. Key quantum algorithms, including the Variational Quantum Eigensolver (VQE) and Quantum Phase Estimation (QPE), demonstrate increasing capability in approximating molecular energies and simulating quantum systems. In parallel, applications in bioinformatics—such as protein folding, genomic search, and combinatorial optimization—highlight the potential of quantum computing to address complex biological problems. Quantum machine learning further extends these capabilities by integrating quantum algorithms with data-driven modeling. However, current progress is constrained by NISQ-era limitations, including noise, limited qubit counts, and scalability challenges. These constraints highlight the need for hybrid quantum–classical approaches and improved error mitigation strategies. Overall, quantum computing represents a complementary computational paradigm that can enhance classical methods in bioinformatics and chemistry. Continued advances in quantum algorithms, hardware, and hybrid modeling frameworks are expected to expand its role in molecular science and computational biology.
Computational chemistry plays a vital role in material sciences. A fast evolving technology called quantum computing has shifted computational capabilities as it promises to solve impossible calculations in some areas of material sciences and drug development. In principle, quantum computers can solve certain problems in chemistry exponentially more quickly than classical computers. As quantum computers have an error-corrected quantum system, it reduces the quantum resources to run the quantum calculations in space drastically using the Trotterization approach with small qubitization. This nascent field is showing fast progress and potential benefits as it can process large amounts of information. The algorithms used for optimization and quantum simulations help to improve the advanced computational calculations for large clusters. These algorithms help in protein structure prediction to network analysis. Yet this nascent field has its own caveats and challenges. In this chapter, we introduce the basic architecture of quantum computing and its promises and limitations in the field of computational chemistry. The quantum algorithms revolutionizing quantum computing are discussed in detail.
Molecular biology and biochemistry interpret microscopic processes in the living world in terms of molecular structures and their interactions, which are quantum mechanical by their very nature. Whereas the theoretical foundations of these interactions are well established, the computational solution of the relevant quantum mechanical equations is very hard. However, much of molecular function in biology can be understood in terms of classical mechanics, where the interactions of electrons and nuclei have been mapped onto effective classical surrogate potentials that model the interaction of atoms or even larger entities. The simple mathematical structure of these potentials offers huge computational advantages; however, this comes at the cost that all quantum correlations and the rigorous many-particle nature of the interactions are omitted. In this work, we discuss how quantum computation may advance the practical usefulness of the quantum foundations of molecular biology by offering computational advantages for simulations of biomolecules. We not only discuss typical quantum mechanical problems of the electronic structure of biomolecules in this context, but also consider the dominating classical problems (such as protein folding and drug design) as well as data-driven approaches of bioinformatics and the degree to which they might become amenable to quantum simulation and quantum computation.

Specifically, we outline a mechanism utilizing quantum algorithms to drastically reduce simulation times and subsequently, incorporate biological information for optimization. This represents a new paradigm in protein structure prediction, offering a pathway to accurately model protein folding and dynamics. The work delves into the theoretical foundations and potential algorithmic implementations, laying the groundwork for future research and development in this exciting field. The focus is on the computational speedup offered by quantum approaches and the strategic integration with existing bioinformatics techniques.
