"What are atoms doing in space anyways?" This talk will provide a brief overview of applications of quantum technologies in space ranging from precise timing and inertial measurements to fundamental physics. Quantum technologies have seen a wide field of applications in medicine, geosciences, computing and communications, in many cases bridging the gap from laboratory experiments to commercial products in the last decade. For terrestrial applications that is. But what about going to space? Quantum physics based sensors and experiments promise higher accuracy, sensitivity or better long term stability as they rely on immutable properties of atoms. When properly manipulated, these (ultra-)cold atoms are likely to outperform state of the art instruments. Experiments conducted on sounding rockets demonstrated important steps like Bose-Einstein Condensate creation during a few minutes in microgravity, enabling more advanced quantum experiments in the future. The International Space Station and the Tiangong Space Station host dedicated experiments like ultrastable clocks as well as flexible research infrastructure for fundamental research benefitting from long free-fall times. However, the deployment of such technologies on satellites is not as advanced. Satellite missions utilizing quantum sensors or performing long term experiments are subject to studies and proposals backed by a broad scientific community aiming at better understanding of climate change, interplanetary navigation or tests of general relativity. First steps towards realization of such missions are taken by ESA, NASA and various national space agencies as well as universities funded by national agencies or the EU. This talk will detect the current state of atoms in space and give an overview of active programs to deploy quantum sensors on operational satellite missions. The focus is on future applications in geosciences and related fields employing the same technology.
Quantum mechanics, once perceived as a purely theoretical domain of physics, has evolved into a cornerstone of modern technological advancement. This paper explores the profound role of quantum principles—such as superposition, entanglement, and wave-particle duality—in shaping contemporary technologies across diverse sectors. By delving into both foundational theories and practical implementations, the study reveals how quantum mechanics underlies the functionality of semiconductors, lasers, magnetic resonance imaging (MRI), and atomic clocks—technologies that are now indispensable to modern society. Moreover, the paper highlights cutting-edge innovations such as quantum computing, quantum cryptography, and quantum sensors, each of which represents a transformative leap in processing power, data security, and precision measurement. Through a combined qualitative and quantitative review of recent research, this work demonstrates that quantum technologies not only enhance performance and efficiency in existing systems but also open unprecedented avenues for communication, computation, and diagnostics. The emergence of quantum networks and the pursuit of quantum supremacy signal a new technological era with far-reaching implications for cybersecurity, artificial intelligence, and materials science. However, the integration of quantum technologies also presents challenges related to engineering scalability, error correction, and ethical governance. This research underscores the need for sustained interdisciplinary collaboration to translate quantum theory into scalable, secure, and socially responsible applications. Ultimately, the study affirms that quantum mechanics is no longer confined to the laboratory; it is embedded within the infrastructure of modern innovation and is poised to redefine the boundaries of what technology can achieve in the 21st century.

Abstract Concerted efforts are underway to establish an infrastructure for a global quantum Internet to realise a spectrum of quantum technologies. This will enable more precise sensors, secure communications, and faster data processing. Quantum communications are a front‐runner with quantum networks already implemented in several metropolitan areas. A number of recent proposals have modelled the use of space segments to overcome range limitations of purely terrestrial networks. Rapid progress in the design of quantum devices have enabled their deployment in space for in‐orbit demonstrations. We review developments in this emerging area of space‐based quantum technologies and provide a roadmap of key milestones towards a complete, global quantum networked landscape. Small satellites hold increasing promise to provide a cost effective coverage required to realise the quantum Internet. The state of art in small satellite missions is reviewed and the most current in‐field demonstrations of quantum cryptography are collated. The important challenges in space quantum technologies that must be overcome and recent efforts to mitigate their effects are summarised. A perspective on future developments that would improve the performance of space quantum communications is included. The authors conclude with a discussion on fundamental physics experiments that could take advantage of a global, space‐based quantum network.
