Abstract

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 ultracold-atom quantum technologies can have in fundamental and applied science through 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, foundational aspects of quantum mechanics, quantum chemistry and the emerging field of quantum biology. 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 convey three main messages. First, atomic quantum technologies have enabled a new way in which 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 taking the center stage in frontier's science. Third, quantum science progress will have capillary impact on society. Thus, 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 these reflections, this perspective review is 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 ultracold-atomic platforms play a vital role in their description and simulation.
