Physics is living an era of unprecedented cross-fertilization among the different areas of science. In this perspective review, we discuss the manifold impact that state-of-the-art cold and ultracold-atomic platforms can have in fundamental and applied science through the development of platforms for quantum simulation, computation, metrology and sensing. We illustrate how the engineering of table-top experiments with atom technologies is engendering applications to understand problems in condensed matter and fundamental physics, cosmology and astrophysics, unveil foundational aspects of quantum mechanics, and advance quantum chemistry and the emerging field of quantum biology. In this journey, we take the perspective of two main approaches, i.e., creating quantum analogues and building quantum simulators, highlighting that independently of the ultimate goal of a universal quantum computer to be met, the remarkable transformative effects of these achievements remain unchanged. We wish to convey three main messages. First, this atom-based quantum technology enterprise is signing a new era in the way quantum technologies are used for fundamental science, even beyond the advancement of knowledge, which is characterised by truly cross-disciplinary research, extended interplay between theoretical and experimental thinking, and intersectoral approach. Second, quantum many-body physics is unavoidably taking center stage in frontier’s science. Third, quantum science and technology progress will have capillary impact on society, meaning this effect is not confined to isolated or highly specialized areas of knowledge, but is expected to reach and have a pervasive influence on a broad range of society aspects: while this happens, the adoption of a responsible research and innovation approach to quantum technologies is mandatory, to accompany citizens in building awareness and future scaffolding. Following on all the above reflections, this perspective review is thus aimed at scientists active or interested in interdisciplinary research, providing the reader with an overview of the current status of these wide fields of research where cold and ultracold-atomic platforms play a vital role in their description and simulation.
This report explores the profound and symbiotic relationship between quantum technology and classical electronics, highlighting their convergence as a transformative force in modern engineering and computation. It details how classical electronic systems are indispensable for the control, measurement, and operation of nascent quantum technologies—including quantum computing, communication, sensing, and simulation—particularly through advanced cryogenic and interface architectures. Concurrently, the inherent scaling limitations of classical electronics at the nano scale are driving innovation inspired by quantum mechanical principles, leading to the development of next-generation devices and the exploration of exotic quantum materials. The analysis addresses significant technical challenges such as noise, scalability, latency, and thermal management, alongside the immense economic and strategic opportunities presented by this frontier. Ultimately, the report projects a future defined by seamless quantum-classical hybrid systems, underscoring that the advancement of quantum technology is deeply reliant on breakthroughs in classical electronics, physics, and computer science. Quantum technology represents a transformative frontier that bridges fundamental physics, advanced electronics, and cutting-edge computer science. Rooted in the principles of quantum mechanics—such as superposition, entanglement, and tunneling—quantum technologies are reshaping how information is processed, transmitted, and measured. The interplay between physics provides the theoretical foundation, while electronics enables precise control and manipulation of quantum systems through devices like qubits and quantum sensors. Meanwhile, computer science contributes with algorithms, error correction, and software frameworks essential for quantum computation and communication. This interdisciplinary synergy is driving breakthroughs in quantum computing, quantum cryptography, and quantum sensing, promising profound impacts on industries ranging from cybersecurity to materials science and artificial intelligence.
Over the past century, quantum theory has taken flight from conceptual breakthroughs, such as wave–particle duality, quantisation of energy, and the uncertainty principle, to practical tools that are the backbone of modern electronics, lasers, semiconductors, and precision measurement systems. In the twenty-first century, this progress under the regime of the second quantum revolution has acquired the ability to directly control, manipulate, and engineer individual quantum systems. Quantum technologies found their pillars in quantum properties, such as superposition, entanglement, and coherence and have exceeded the boundaries of classical physics. The steady theoretical advances, combined with experimental progress, have brought quantum concepts closer to real-life use. Significant progress has made in filed of computation, communication, sensing, navigation, medicine, cyber security, and national defense undr the guidance of quantum technology.
