Sensors based on quantum mechanical properties of light and matter offer unique capabilities and performance sometimes difficult to achieve using classical approaches. NASA Engineering and Safety Center has convened an independent external panel, comprised of Quantum Sensing Experts from the Government, DoD, academia, and Federally funded Research and Development Centers to conduct an independent technical assessment of the agency's capabilities in Quantum Sensing to understand NASA's internal needs and competencies related to Quantum Sensing and compare agency capabilities with those available externally including industry, academia, and other government agencies. This assesses focused on suitability of quantum sensing for current and future NASA needs. Measurement and sensing needs across NASA were reviewed as a driver for the possible incorporation of existing quantum sensors into the NASA portfolio and the development of next-generation quantum sensors. This presentation will describe a set of findings and recommendations to guide future investment and activity at NASA in this important and growing technology area.
Quantum physics has transitioned from a purely theoretical discipline to a transformative technological foundation influencing modern space science and engineering. From ultra-precise atomic clocks enabling global navigation systems to quantum sensors enhancing spacecraft navigation and quantum communication networks promising unbreakable encryption, quantum mechanics now plays a pivotal role in space technology. This research paper explores the theoretical foundations of quantum physics and examines its applications in satellite systems, deep-space exploration, communication networks, gravitational sensing, propulsion research, and cosmology. It further discusses current missions led by agencies such as NASA, European Space Agency, and China National Space Administration, highlighting advancements in space-based quantum experiments. The paper concludes with future prospects, technical challenges, and the role of quantum technology in shaping next-generation space exploration.
The Space Science and Technology Partnership Forum (S&T Forum), comprised of an interagency team from the National Aeronautics and Space Administration, the National Reconnaissance Office, and the United States Space Force, presents findings and recommendations from a study on the state of quantum sensors for space applications, enabling component technologies, facilities, and developers across government, industry, and academia. The following five areas of quantum sensing technology (listed in alphabetical order) were identified as being of near-term interest to all three S&T Forum agencies: atomic clocks, atom interferometers, quantum magnetometers, Rydberg sensors, and single photon detectors. This paper focuses on two recommendations: 1) increased collaboration between the S&T Forum, industry, and academia on the development of enabling components for the five quantum sensing technology areas, and 2) challenges and future opportunities to take quantum sensors from the laboratory to space. Through this study, the S&T Forum found a diverse and broad community of quantum sensing developers in the United States that are leading efforts in research, testing, manufacturing, and qualification of quantum sensors and their enabling component technologies. There are common needs across quantum sensing technology areas. To address the common needs, the S&T Forum agencies are encouraged to utilize existing models and mechanisms to enable co-development of enabling component technologies and to explore new avenues for engagement with the quantum sensing community.
As NASA spacecraft explore deeper into the cosmos, speed-of-light-limited signal delays make it increasingly impractical to command missions from Earth. Future spacecraft will need greater onboard computing capacity to mimic human-level intelligence and autonomy. The solution might come from quantum computers, which offer properties of size, power, and robustness that are ideally suited to the space environment. The potential of quantum technologies goes far beyond enhanced computing capacity. Future space missions will involve direct participation of non-NASA scientists. This will necessitate allowing more open access to spacecraft systems via free-space communication links. Quantum cryptography would allow such channels to be made absolutely secure and invulnerable to attack by malevolent hackers. To explore these possibilities, this article describes the progress to date in understanding how quantum computers and related quantum information-processing devices might advance space exploration.
The National Aeronautics and Space Administration's Deep Space Quantum Link mission concept enables a unique set of science experiments by establishing robust quantum optical links across extremely long baselines. Potential mission configurations include establishing a quantum link between the Lunar Gateway moon-orbiting space station and nodes on or near the Earth. This publication summarizes the principal experimental goals of the Deep Space Quantum Link. These goals, identified through a multi-year design study conducted by the authors, include long-range teleportation, tests of gravitational coupling to quantum states, and advanced tests of quantum nonlocality.
"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.
