Composition Patterns
===================

psipose follows a "composition over inheritance" design.
Components can be mixed and matched independently.

Example: Custom Encoder + Ansatz
---------------------------------

.. code-block:: python

   from psipose.feature_maps import AngleFeatureMap
   from psipose.ansatze import StronglyEntanglingAnsatz
   from psipose.estimators import VQCClassifier

   clf = VQCClassifier(
       encoder=AngleFeatureMap(rotation="X"),
       ansatz=StronglyEntanglingAnsatz(layers=3),
       n_qubits=4,
       max_iter=200
   )
   clf.fit(X, y)
