# Applications and Infrastructure

**English** · <a href="../../../zh/manual/algorithms/groups/applications.html">简体中文</a>

Domain applications assembled across subpackages (QFVM, QHAM) and the infrastructure tooling the algorithm pages rely on (the math-function library). Entries come from `oracq.applications` and `oracq.infrastructure`, belonging to the application layer (C6) or to infrastructure modules.
