The C API provides various data structures for representing fermionic operators in different bases.

.. table::

  ==================================== ============================================================
  :c:struct:`QfFermionOperator`        An operator in the basis of the second-quantization creation
                                       and annihilation operators.
  :c:struct:`QfMajoranaOperator`       An operator in the basis of Majorana fermions.
  :c:struct:`QfEdgeVertexOperator`     An operator in the basis of the edge and vertex operators.
  :c:struct:`QfTransferVertexOperator` An operator in the basis of the transfer and vertex
                                       operators.
