Functions#

`subunitary_selection_on_index`(unitary_matrix, ...)	This function returns a unitary between the indexes selected, and verifies the indexes are valid by checking that
`subunitary_selection_on_range`(unitary_matrix, stop_index)	This function returns a unitary between the indexes selected, and verifies the indexes are valid by checking that
`verify_matrix_is_unitary`(→ bool)	Verify that the matrix is unitary.

subunitary_selection_on_index(unitary_matrix: jax.numpy.ndarray, rows_index: jax.numpy.ndarray | tuple, columns_index: jax.numpy.ndarray | tuple)[source]#

This function returns a unitary between the indexes selected, and verifies the indexes are valid by checking that the output matrix is also a unitary.

TODO implement validation of a 2D matrix.

subunitary_selection_on_range(unitary_matrix: jax.numpy.ndarray, stop_index: tuple, start_index: tuple | None = (0, 0))[source]#

This function returns a unitary between the indexes selected, and verifies the indexes are valid by checking that the output matrix is also a unitary.

TODO implement validation of a 2D matrix.

verify_matrix_is_unitary(matrix: jax.numpy.ndarray) → bool[source]#

Verify that the matrix is unitary.

Parameters:: matrix (jnp.ndarray) – The matrix to verify.
Returns:: True if the matrix is unitary, False otherwise.
Return type:: bool
