The most striking example of this transformation is the emergence of quantum computers. The Second Quantum Revolution, which began in the early 21st century, focuses on harnessing quantum phenomena such as superposition, entanglement, and tunneling to develop groundbreaking technologies in computation, communication, and precision measurement (Arute et al., 2019). In this context, concepts from particle physics, such as Weyl fermions and Majorana fermions, have found innovative applications in condensed matter physics, electronics, materials science, and even nanomedicine. For instance, Majorana fermions—originally predicted as elementary particles—are now explored as potential building blocks for topological quantum computers due to their non-Abelian statistics, which could enable fault-tolerant quantum computation (Lutchyn et al., 2018). Similarly, two-dimensional (2D) monolayer materials (e.g., graphene, MoS₂, WS₂) have revolutionized electronics by enabling ultra-low energy consumption and high electron mobility. Recent advances in 2D materials include their use in flexible electronics, photovoltaics, and quantum optoelectronics (Xu et al., 2020). Nanotechnology has become an indispensable tool across all scientific disciplines. In nanomedicine, nanoparticle-based drug delivery systems have enabled targeted cancer therapies, minimizing side effects while maximizing efficacy (Wang et al., 2021). Additionally, quantum dots are employed in high-resolution biomedical imaging and biosensing, offering unparalleled sensitivity. These developments underscore nanotechnology’s role not only in engineering but also in advancing life sciences. The Second Quantum Revolution will extend its impact beyond information technology, addressing global challenges in energy, healthcare, and environmental sustainability. For example, quantum simulations can model complex molecular interactions, accelerating drug discovery and materials design (Cao et al., 2019). Such research will likely catalyse a technological explosion unprecedented in human history.
