Quantum-HPC: Achievements, Challenges, and the Road Ahead


Workshop: 3rd International Workshop on HPC Testing and Evaluation of Systems, Tools, and Software (HPCTESTS 2025)

Authors: Laura Schulz (Argonne National Laboratory (ANL))

Abstract: Abstract: Quantum–HPC integration has advanced from early experiments to operational prototypes that connect quantum accelerators with leadership-class supercomputers. This talk reviews what has been achieved so far like hybrid runtimes, middleware layers, and workflow orchestration bridging HPC and quantum systems, and what continues to be challenges, like multiple emerging solution and standards, adoption, use cases, and sustained software ecosystems.
It also examines structural challenges such as aligning hardware roadmaps with software readiness and maintaining realistic expectations of computational utility. Rather than promising speedups, the focus is on what hybrid infrastructures enable today: reproducible experimentation, system co-design, and preparation for future fault-tolerant regimes.
