Quantum-Enhanced Critical Minerals Mapping Act of 2026

This legislation directs the Secretary of the Interior, through the Director of the United States Geological Survey, to establish a program within 180 days to conduct original quantum-enhanced geophysical surveys . The primary goal is to improve existing data for the discovery and characterization of critical mineral and rare earth element deposits located on or adjacent to Federal lands. These surveys will specifically employ quantum gravity gradiometry over at least three priority critical minerals focus areas identified under the Earth Mapping Resources Initiative (Earth MRI) program, with a focus on western rare earth element zones. The program requires comparing the new quantum gravity gradiometry data with existing classical geophysical survey data to quantify improvements in resolution and depth penetration. All collected survey data must be integrated into the Earth MRI national minerals database and made publicly accessible to facilitate private-sector investment in domestic critical mineral development. The Secretary is also mandated to coordinate with the Department of Energy and State Geological Surveys, and to the maximum extent practicable, carry out surveys through cooperative research and development agreements with private quantum sensing firms. Within 24 months, a report detailing the program's findings, including a cost-benefit analysis and recommendations, must be submitted to Congress.
