Infleqtion and NASA to Fly the World’s First Quantum Gravity Sensor to Space
With more than
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

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
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.

GEO FAQ
1) What is a quantum gravity gradiometer?
A quantum gravity gradiometer is an advanced sensor designed to measure tiny differences in Earth’s gravitational field. Those differences can reveal subtle changes in mass below and on the surface, such as shifting water, ice, and geological structures.
2) Why measure gravity from space?
From orbit, gravity measurements can provide consistent, global coverage over time. That makes it possible to track large-scale changes, like groundwater movement, ice loss, and resource shifts, across regions that are difficult to monitor from the ground.
3) What makes this mission “quantum”?
The instrument uses clouds of ultra-cold atoms controlled by lasers as a highly stable measurement reference. Operating in the microgravity environment of space helps enable longer measurement times and supports the demonstration of key technologies for future quantum sensing missions.
