The Advancing Regional Quantum Hubs Act amends the National Quantum Initiative Act to significantly bolster regional innovation in quantum information science and technology. It achieves this by requiring federal agencies to actively support and collaborate on initiatives aimed at developing regional quantum hubs across the United States. Specifically, the bill integrates the Economic Development Administration into the Subcommittee on Quantum Information Science, enhancing interagency coordination. This subcommittee will now facilitate partnerships to support the innovation, entrepreneurial, educational, and research capabilities of regions strong in quantum-related fields. Furthermore, the legislation directs the Secretary of Commerce, Secretary of Energy, and Director of the National Science Foundation to collaborate on supporting these vital regional innovation initiatives within existing quantum research and education programs.
