The Quantum-Enhanced Critical Minerals Mapping Act of 2026 directs the Secretary of the Interior to conduct advanced geophysical surveys using quantum technology to locate and map critical minerals and rare earth elements on federal lands. The bill requires the U.S. Geological Survey to deploy quantum gravity gradiometry equipment across at least three priority areas, focusing particularly on western regions with rare earth deposits, and to compare the results with traditional surveying methods to demonstrate improvements in detection capabilities. The survey data must be integrated into a public database accessible to mining companies and other private sector entities to encourage domestic mineral development and reduce dependence on foreign sources. The Secretary has 180 days from enactment to establish the program and must partner with Department of Energy laboratories and private quantum sensing firms to leverage their expertise and reduce federal costs. Congress requires a comprehensive report within 24 months that documents findings, compares quantum versus classical survey results, assesses the technology's potential, and provides recommendations for expanding the program nationwide.
