使用示例
--------

Schmidt 编码
~~~~~~~~~~~~

.. code-block:: python

   from janus.encode import schmidt_encode
   import numpy as np

   data = [1/np.sqrt(2), 1/np.sqrt(2), 0, 0]
   circuit = schmidt_encode(q_size=4, data=data, cutoff=1e-4)

高效稀疏编码
~~~~~~~~~~~~

.. code-block:: python

   from janus.encode import efficient_sparse

   result = efficient_sparse(data, n_qubits=4)
