## AI overview

This article presents quantum-augmented applications as hybrid systems that integrate Quantum Processing Units with classical software pipelines. It describes delegating targeted computationally difficult subroutines to QPUs while retaining classical business logic, data preprocessing, orchestration, and optimization, and discusses practical constraints including noise, transpilation latency, and network overhead.
