  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
mini-apps across heterogeneous quantum-HPC infrastructure, making it a valuable
tool for performance characterizations and middleware development.
