Quantum sensors will play a major role in space science applications. This is because of the promising ability of these sensors to outperform their classical counterparts. Photonics is a major support technology for quantum sensors, but further developments are required to make components and systems possible for space applications. Photonic systems based on crystalline whispering gallery resonators are poised to address some of the needs of future sensors. A laser system based on this approach is being developed in support of Space Quantum Gravity Gradiometer using cesium atoms and is briefly described.

The National Aeronautics and Space Administration (NASA) develops a broad range of technologies to support space-based quantum sensing and communications, uses the space environment to study fundamental quantum processes to advance our knowledge of physics, and develops algorithms to attack complex science problems that might be solved using quantum computing. This paper describes quantum sensors that NASA has flown on space missions, investments that NASA is making to develop quantum sensors, and possible approaches to employ quantum sensing to study the attributes of distant stars and planets, the Sun, Earth, and fundamental properties of matter.
Quantum sensors have been named a top 10 emerging technology by the World Economic Forum in 2020. This is mainly driven by their imminent application potential and the ability to open up qualitatively new sensing areas, such as sensing into the ground, or seeing the brain at work. We are now just one step away from commercial breakthrough applications in civil engineering and clinical trials. With this success, the next step will be to develop integrated photonics components to open up mass markets in water, navigation and gaming. I will provide an overview of the working principle of an atomic quantum sensor and lay out the parameter needs for photonic integration.
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.
Recent developments in quantum technology have resulted in a new generation of sensors for measuring inertial quantities, such as acceleration and rotation. These sensors can exhibit unprecedented sensitivity and accuracy when operated in space, where the free-fall interrogation time can be extended at will and where the environment noise is minimal. European laboratories have played a leading role in this field by developing concepts and tools to operate these quantum sensors in relevant environment, such as parabolic flights, free-fall towers, or sounding rockets. With the recent achievement of Bose–Einstein condensation on the International Space Station, the challenge is now to reach a technology readiness level sufficiently high at both component and system levels to provide “off the shelf” payload for future generations of space missions in geodesy or fundamental physics. In this roadmap, we provide an extensive review on the status of all common parts, needs, and subsystems for the application of atom-based interferometers in space, in order to push for the development of generic technology components.
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.
A significant variety of photonic devices is required for the implementation of quantum sensors, computers and communication networks. This presentation will describe the current state-of-the-art and future possibilities for key photonic devices that enable quantum technologies, such as photon sources, photon detectors, optical amplifiers, electro-optic modulators and paths towards the integration of these devices into compact, highly functional components. Specific requirements on these devices that come from quantum technology demands will be explored and technology solution approaches will be described. We will include examples of devices being developed at Freedom Photonics as well as in other leading quantum technology organizations.
