Custom operations
=================

**Module name:** :mod:`pennylane_cirq.ops`

.. currentmodule:: pennylane_cirq.ops

Sometimes the Target Framework may accept more operations
than available by core PennyLane. The plugin can define
these operations such that PennyLane can understand/apply them,
and even differentiate them.

This module contains some example PennyLane qubit operations.

The user would import them via

.. code-block:: python

    from pennylane_cirq.ops import S, T, CCNOT

To see more details about defining custom PennyLane operations,
including more advanced cases such as defining gradient rules,
see https://pennylane.readthedocs.io/en/latest/API/overview.html

Operations
----------

.. autosummary::
    BitFlip
    PhaseFlip
