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 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 in
Execution phase advances quantum-enabled approaches designed to improve energy grid efficiency, resilience, and operational scale Infleqtion, a global leader in quantum computing and quantum sensing, today announced it has executed its contract with the U.S. Department of Energy's Advanced Research Projects Agency-Energy (ARPA-E), formally launching development under its $6.2 million Enhancing Neutral-atom Computers for Optimizing Delivery of Energy (ENCODE) project. This program, which includes key collaborations with Argonne National Laboratory, the National Laboratory of the Rockies (NRL), EPRI, and ComEd, is the first quantum project for the department focusing on advancing the applic
Live test between Chicago and Northwest Indiana shows up to 40X improvement over GPS for keeping digital systems synchronized Infleqtion, a global leader in quantum sensing and quantum computing powered by neutral-atom technology, today announced a successful live demonstration with Quantum Corridor showing how critical digital infrastructure can stay precisely synchronized without relying on GPS. Quantum Corridor is a quantum-safe, ultra-fast, and highly secure fiber-optic network in the Midwest enabling next-generation communication. The demonstration was conducted across 21.8 kilometers of live urban fiber between Chicago's ORD10 Data Center (350 Cermak) and the Digital Crossroad Data
