单比特门分解
~~~~~~~~~~~~

.. code-block:: python

   from janus.decompose import decompose_one_qubit
   import numpy as np

   # 分解任意单比特酉矩阵
   U = np.array([[1, 0], [0, 1j]])
   gates = decompose_one_qubit(U)

两比特门分解
~~~~~~~~~~~~

.. code-block:: python

   from janus.decompose import decompose_two_qubit_gate

   gates = decompose_two_qubit_gate(U)

KAK 分解
~~~~~~~~

.. code-block:: python

   from janus.decompose import decompose_kak

   result = decompose_kak(U)
