PRESS RELEASE — Monarch Quantum extends congratulations to Infleqtion on receiving the $20 million NASA follow-on contract supporting the Quantum Gravity Gradiometer Pathfinder (QGGPf). Led by NASA’s Jet Propulsion Laboratory in Southern California, the mission is anticipated to demonstrate the world’s first space-based Earth quantum gravity gradient sensor.
The award advances the mission into its next phase of hardware development and testing. Monarch Quantum supports Infleqtion ‘s efforts on the mission by supplying integrated photonics hardware that delivers precise, stable light required to meet the performance of the sensor.
“NASA’s continued investment in this pathfinder mission validates the progress being made to move quantum sensing beyond the laboratory and into demanding operational environments,” said Tim Day, Chief Executive Officer and Chairman of Monarch Quantum . “Space-qualified quantum systems require exceptional systems engineering paired with reliability and precision. We are proud to support Infleqtion and NASA in advancing the photonics subsystems needed to make this mission possible.”
QGGPf is designed to demonstrate quantum sensor technologies that could inform future gravity-mapping instruments in low-Earth orbit. By measuring subtle variations in Earth’s gravitational field, future systems could provide new insight into changes in groundwater, ice, natural resources, and other geophysical conditions, supporting planetary science, environmental resilience, and national security decision-making.
Monarch Quantum develops compact photonics engines that integrate lasers, micro-optical components, fibers, and advanced control electronics into reliable subsystems. By managing the photonics complexity that underlies the quantum system, Monarch enables quantum instrument developers to focus on core physics, sensor architecture, and applications.
For QGGPf, this approach helps translate the highly controlled optical performance required for cold-atom sensing into a compact, rugged, and repeatable platform suitable for the demanding conditions of spaceflight development and testing.
“Quantum sensing is a systems challenge as much as it is a physics challenge,” Day added. “The path to deployment depends on bringing together atomic physics, photonics, electronics, packaging, manufacturing, and rigorous qualification. This mission is an important example of the U.S. quantum ecosystem working across that full value chain.”
The mission builds on NASA’s heritage in space-based gravity mapping, including the GRACE and GRACE-FO missions, as well as prior work by JPL and Infleqtion on the Cold Atom Lab (CAL) aboard the International Space Station. NASA and Infleqtion expect to complete instrument hardware development, expecting to launch in 2030.
