Quantum catalysis is a cutting-edge, interdisciplinary field that brings together quantum physics, chemistry and materials science. At its core, this exploration delves into how the intriguing aspects of quantum mechanics—such as entanglement, coherence and the manipulation of quantum states—can be utilised to speed up or facilitate chemical reactions that would be difficult or even impossible to achieve through conventional methods. In classical catalysis, a catalyst functions by reducing the activation energy required for a reaction to take place.

In classical catalysis, a catalyst functions by reducing the activation energy required for a reaction to take place. Quantum catalysis, however, goes a step further by tapping into the unique behaviours of quantum systems. This allows for transformations between quantum states or boosts chemical reactivity, all while the catalyst itself remains unchanged and ready to be used again. The roots of this field are found in quantum information theory, where special quantum systems—called quantum catalysts—can make specific state changes possible that would otherwise be forbidden. Over time, this concept has expanded to encompass a broad range of topics, including quantum coherence, thermodynamics and nonlocal operations. It also involves practical platforms such as quantum dots, topological materials and chiral quantum systems. The potential of quantum catalysis is already being realised in several areas: Energy conversion: Making energy processes more efficient and sustainable. Chemical sensing and photocatalysis: Enabling more precise and selective reactions. Quantum information processing: Helping to advance the next generation of computing technologies. Recent progress in the field includes the creation of universal quantum catalysts, the use of machine learning to discover new catalysts and experimental breakthroughs with nanoscale materials. Despite these advances, challenges remain, especially in translating theoretical models into practical, real-world applications and navigating the complexities of quantum systems. As research continues, quantum catalysis is expected to revolutionise a wide range of fields, from clean energy to quantum computing. By enabling more efficient, selective and innovative chemical processes, it holds great promise for addressing some of society’s most pressing scientific and technological challenges.
