About C2QA

The U.S. Department of Energy Office of Science has established five National Quantum Information Science (QIS) Research Centers. These centers will accelerate the transformational advances in basic science and quantum-based technologies needed to assure continued U.S. leadership in QIS, consistent with the National Quantum Initiative Act. Led by Brookhaven National Laboratory, the Co-design Center for Quantum Advantage is building the fundamental tools necessary to create scalable, distributed, and fault-tolerant quantum computer systems.
