.. py:class:: UnconstrainedVariationalUnitary

   Bases: :py:obj:`peropq.variational_unitary.VariationalUnitary`


   class representing the variational unitary ansataz, with no prior constraint on the variational parameters.


   .. py:method:: update_theta(new_array)

       Update theta.

      :param new_array: the new array containing the variational parameters. It's shape must be (R,  n_terms).



   .. py:method:: flatten_theta(theta)

      Returns an input theta as flatten depth*n_terms array. Useful to pass to a minimization function.



   .. py:method:: unflatten_theta(flat_theta)

      Returns the flattened variational parameters as an array with shape (depth,n_terms).



   .. py:method:: get_flattened_theta()

      Return the flatten current variational parameters.



   .. py:method:: get_initial_trotter_vector()

      Get the variational parameters corresponding to the Trotterization. Useful to initialize the optimization.



   .. py:method:: set_theta_to_trotter()

      Sets the variational parameters to the Trotter parameters.
