Adding a New Encoder
=====================

To add a new encoder, inherit from ``BaseEncoder``:

.. code-block:: python

   from psipose.encoders._base import BaseEncoder
   import pennylane as qml

   class MyEncoder(BaseEncoder):
       """My custom encoder."""

       def __init__(self, param1=default_value):
           self.param1 = param1

       def fit(self, X):
           """Fit encoder to data (determine n_qubits if needed)."""
           self.n_qubits_ = X.shape[1]  # or custom logic
           return self

       def encode(self, x, wires):
           """Encode a single sample x onto wires."""
           # Your encoding logic here
           for i, wire in enumerate(wires[:len(x)]):
               qml.RY(x[i], wires=wire)
