Key Terms
quantum gravity gradiometertechnical
A quantum gravity gradiometer is a high‑precision sensor that detects tiny differences in the strength of gravity across short distances using quantum‑based measurements. Think of it as a very sensitive ruler for gravitational changes: it can reveal hidden structures underground, track mass movements, or improve navigation where GPS fails. Investors care because the technology can enable new services in resource exploration, infrastructure monitoring, defense and advanced navigation, creating potential commercial and government demand.
low Earth orbittechnical
Low Earth orbit (LEO) is the region of space close to Earth, roughly from about 160 to 2,000 kilometers above the surface, where satellites and spacecraft circle the planet quickly—think of it as a busy highway just overhead. It matters to investors because many communications, imaging and data services rely on satellites in LEO; their shorter lifespans, lower launch costs, crowded lanes and debris risks directly affect the cost, revenue potential and operational risks of companies that build, launch or use these satellites.
microgravitytechnical
Microgravity is a condition where objects experience almost no net weight because they are in continuous free-fall, such as aboard orbiting spacecraft; think of passengers feeling weightless in a smoothly falling elevator. For investors, microgravity matters because it enables scientific experiments and manufacturing processes that behave very differently than on Earth, potentially creating novel drugs, materials, or technologies, changing development timelines, costs, market opportunities and regulatory considerations.
cold atomtechnical
A cold atom is an individual atom that has been cooled to extremely low temperatures so its motion slows to a crawl and quantum behaviors become visible; think of slowing a speeding car to watch tiny vibrations. Investors care because cold-atom techniques power next-generation technologies—ultra-precise clocks, sensors, and quantum computers—that can create new products, services, and market opportunities for companies in optics, defense, and computing.
ultracoldmedical
Ultracold describes storage or transport conditions far colder than a household freezer, typically around minus 70 to minus 80 degrees Celsius, used to preserve sensitive biological products like certain vaccines, cells or proteins. It matters to investors because requiring ultracold handling adds specialized equipment, higher logistics costs, limited distribution locations and regulatory oversight, all of which can affect a product’s marketability, launch speed and profit margins — think of it as needing a deep‑freeze supply chain instead of a regular fridge.
quantum sensingtechnical
Quantum sensing uses the unusual behavior of tiny particles to measure physical quantities—like magnetic fields, time, or motion—with far greater precision than conventional sensors. For investors, it matters because this leap in sensitivity can enable new products and markets (better medical imaging, navigation without GPS, or faster material testing), potentially creating high-growth opportunities for companies that commercialize reliable, scalable devices.
neutral-atom technologytechnical
Neutral-atom technology uses individually trapped, electrically neutral atoms as the basic units for storing and manipulating information, typically held in place and controlled by light or magnetic fields. Investors should care because this approach aims to build highly scalable, precise quantum devices and sensors that could enable new computing power and measurement capabilities; like arranging beads on a board, progress milestones and manufacturing scalability drive long-term value and risk.
gravity gradienttechnical
Gravity gradient is the change in gravitational pull across the length of an object so one end feels a slightly different tug than the other, creating a twisting force that can change orientation. Imagine holding a long rod while one end is pulled harder than the other in a tug-of-war. For investors, gravity gradient matters because it affects the design, stability and operating costs of satellites, heavy structures and some mining or engineering projects, influencing capital expenditure, risk profiles and insurance or regulatory requirements.
With more than $20 million in contracted mission funding to date, the Quantum Gravity Gradiometer Pathfinder Mission, Led by NASA’s Jet Propulsion Laboratory in Southern California, Advances U.S. Leadership in Quantum Space Sensing
LOUISVILLE, Colo.--(BUSINESS WIRE)--
Infleqtion, a global leader in quantum sensing and quantum computing powered by neutral-atom technology, announced its role as a collaborator on NASA’s Quantum Gravity Gradiometer Pathfinder (QGGPf) mission. Led by NASA’s Jet Propulsion Laboratory (JPL), the mission will fly the first quantum sensor capable of measuring the Earth's gravitational field and its gradients; signals that are used today to monitor mass dynamics on the planet's surface. The quantum instrument will be aboard a dedicated satellite in low Earth orbit (LEO). This program follows Infleqtion’s announcement to go public through a merger with Churchill Capital Corp X (NASDAQ: CCCX).
The QGGPf mission is designed to demonstrate quantum sensor technologies that could transform how Earth’s gravity is measured from space. The quantum sensor is designed to monitor mass dynamics across the planet’s surface, including changes in water, ice and land, while operating in microgravity, which enables longer interaction times and correspondingly improved measurement sensitivities. As a technology pathfinder, the mission will help inform the design of future science-grade instruments, representing a major step forward in U.S. leadership in space-based quantum sensing and strategic intelligence.
This project showcases what is possible when NASA and U.S. industry collaborate to push the boundaries of frontier science and technology. QGGPf builds on NASA’s long legacy of space-based gravity mapping and applies Infleqtion’s quantum engineering capabilities to enable a new class of measurement techniques designed specifically for the microgravity environment of space.
A Quantum Leap in Geospatial Precision and Strategic Sensing
With more than $20 million in contracted mission funding to date, the QGGPf mission, with contributions from NASA’s Goddard Space Flight Center, the University of Texas at Austin, Infleqtion, Monarch Quantum, and Jemba9, will fly the first standalone quantum gravity sensor in orbit.
“Quantum sensing opens an entirely new domain for U.S. space leadership,” said Dana Anderson, Chief Science Officer at Infleqtion. “By deploying this technology in orbit, we are demonstrating the feasibility of quantum gravity sensing in space and laying the groundwork for future capabilities that can deliver unprecedented insight into our planet.”
By directly measuring subtle variations in Earth’s gravitational field, the mission aims to demonstrate technologies that will help reduce risk for future quantum gravity instruments. These future systems could enable higher-resolution insights into how underground water, ice, and natural resources shift over time, critical data for understanding planetary health, strengthening national resilience, and supporting long-term economic and security planning. The one-year mission is expected to launch in 2030.
Proven Quantum Heritage
QGGPf builds on work done by JPL and Infleqtion on the Cold Atom Lab (CAL) program aboard the International Space Station, and on NASA’s long heritage mapping Earth’s gravitational field through the GRACE mission series.
Infleqtion’s role on the QGGPf project includes the design, maturation, and integration of the quantum core of the sensor, encompassing its vacuum, laser, and control subsystems. The cold-atom system, based on ultracold rubidium atoms cooled to near absolute zero, is designed to enable direct gravity gradient measurements from space with unprecedented precision.
Accelerating Quantum-to-Space Transition
The mission further marks a significant milestone in America’s growing quantum ecosystem, showcasing how public–private relationships can accelerate the transition from fundamental research to operational capability. Beyond Earth science, quantum sensing in space will enable advances in navigation, resource management, and national security, where precision and autonomy are critical.
NASA and Infleqtion plan to complete the instrument hardware development over the next three years, followed by flight demonstration.
