Pioneering Quantum-Supercomputing Integration: U.S. Leadership in the Next Computing Era

Hideki Tomoshige and Shruti Sharma

Integrating quantum computers into U.S. world-class supercomputers is now a strategic imperative for U.S. technological leadership in the next era of computing. Hybrid systems will synergize classical and quantum computing and deliver breakthroughs faster in optimization, simulation, and scientific discovery.

While the United States leads in supercomputing and quantum computing, it lags behind Europe and Japan in developing hybrid quantum-supercomputing systems. Increased federal investment in testbeds, open-source software stacks, and workforce development can position the United States to shape and maintain competitiveness in quantum-supercomputing systems and capitalize on quantum breakthroughs when practical quantum advantages emerge.
