The "Support for Quantum Supply Chains Act" proposes amendments to the existing National Quantum Initiative Act, aiming to strengthen the United States' position in quantum information science, technology, and engineering. Its primary goal is to accelerate the development of domestic supply chain technologies for quantum applications, thereby enhancing United States competitiveness and mitigating risks within the quantum supply chain. Specifically, the bill mandates the National Institute of Standards and Technology (NIST) to establish or expand partnerships with public and private sector entities . These collaborations will focus on accelerating the development of quantum supply chain technologies and reducing vulnerabilities across the sector. Furthermore, NIST will be required to identify critical quantum supply chain technologies essential for maintaining U.S. leadership and competitiveness in the rapidly evolving quantum field.
