Infleqtion

Infleqtion (formerly ColdQuanta), headquartered in Boulder, Colorado, is a cold atom quantum technology company commercializing quantum sensors, atomic clocks, and quantum computing hardware derived from ultracold atomic physics — where atoms are laser-cooled to within billionths of a degree of absolute zero, enabling quantum mechanical effects that create sensors and clocks orders of magnitude more precise than conventional electronics.

Cold atom technology works by using laser light to slow and trap atoms until they essentially stop (temperatures measured in nanokelvins), at which point quantum superposition and interference effects become macroscopically observable. This enables accelerometers based on atom interferometry (measuring gravity and inertial forces by counting quantum interference fringes rather than spring deflections), atomic clocks based on microwave transitions that keep time more accurately than cesium fountain clocks, and quantum magnetometers for detecting tiny magnetic fields.

Infoleqtion's highest-profile space achievement is building the Physics Package Assembly for NASA's Cold Atom Lab (CAL) aboard the ISS — the world's first quantum scientific laboratory in space, continuously operating since 2018. CAL creates Bose-Einstein Condensates (ultracold matter clouds) in microgravity where they expand for longer times than possible on Earth, enabling fundamental quantum physics research on matter wave properties. Infleqtion's space-qualified physics package demonstrates the company's ability to deliver cold atom hardware that survives launch vibration and operates reliably in orbit.

For NASA JPL, Infleqtion is developing the Quantum Gravity Gradiometer Pathfinder (QGGP) — an atom interferometry instrument to measure gravity field gradients from orbit, with Earth science applications for geodesy, ice sheet mass balance monitoring, and underground resource detection. A strategic partnership with Voyager Technologies (commercial space station operator) targets ISS and future Starlab deployment of quantum sensor payloads for fundamental science and geophysical observation missions.
