S. 579

Department of Energy Quantum Leadership Act of 2025 This bill modifies and reauthorizes various Department of Energy (DOE) programs related to quantum research and development and establishes several new, related research programs. Specifically, the bill expands the scope of DOE’s quantum information science research program to include research, development, and demonstration on quantum information science, engineering, and technology. Among other requirements, DOE must (1) establish an early-stage research and development program in high-performance quantum computing; (2) study quantum science, engineering, and technology supply chain needs; and (3) establish a university-led trainee program to address quantum workforce development needs. The bill also reauthorizes the National Quantum Information Science Research Centers and the Quantum User Expansion for Science and Technology program through FY2030. Further, the bill modifies DOE’s quantum network infrastructure program to require research related to the development of (1) quantum network and entanglement distribution protocols or applications, and (2) high-efficiency room-temperature photon detectors for quantum photonic applications. Finally, the bill establishes an instrumentation and infrastructure program to maintain U.S. leadership in quantum information science, engineering, and technology; develop domestic quantum supply chains; and provide resources for the broader scientific community. In carrying out the program, DOE must develop, design, build, purchase, and commercialize specialized equipment, laboratory infrastructure, and state-of-the-art instrumentation. In coordination with industry and institutions of higher education, DOE must support the development of quantum foundries focused on meeting the device, hardware, software, and materials needs of the scientific community and the quantum supply chain.
