Quantum Mini-Apps: A Framework for Developing and Benchmarking Quantum-HPC Applications

With the increasing maturity and scale of quantum hardware and its integration into HPC systems, there is a need to develop robust techniques for developing, characterizing, and benchmarking quantum-HPC applications and middleware systems.This requires a better understanding of interaction, coupling, and common execution patterns between quantum and classical workload tasks and components.This paper identifies six quantum-HPC execution motifs-recurring execution patterns characterized by distinct coupling and interaction modes.These motifs provide the basis for a suite of quantum mini-apps -simplified application prototypes that encapsulate essential characteristics of production systems.To support these developments, we introduce a mini-app framework that offers the necessary abstractions for creating and executing miniapps across heterogeneous quantum-HPC infrastructure, making it a valuable tool for performance characterizations and middleware development.
