Quantum computing is increasingly converging with high-performance computing, prompting the need for a strategic adoption approach. A problem-first playbook is essential, where HPC centers identify bottlenecks, assess classical options, and evaluate quantum acceleration with clear return on investment and procurement targets. According to Bob Sorensen, Chief Quantum Analyst at Hyperion Research, cloud versus on-premises tradeoffs must be carefully weighed, and quantum hardware should have short lifecycles with upgrade paths1. Seamless integration is a top concern for HPC managers. As quantum developments advance, the urgency to plan for post-quantum cryptography increases, particularly with potential disruptions from quantum-enabled attacks on cryptographic systems. This convergence matters to practitioners because it underscores the need to prioritize practical definitions of quantum advantage and develop a roadmap for cryptographic migration to ensure the long-term security of sensitive data.
