Find the Pauli-representation of InteractionOperator for Bravyi-Kitaev Super fast (BKSF) algorithm.

Pauli-representation of general FermionOperator is not possible in BKSF. Also, the InteractionOperator given as input must be Hermitian. In future we might provide a transformation for a restricted set of fermion operator.

operator InteractionOperator.

transformed_operator An instance of the QubitOperator class.

TypeError If operator is not an InteractionOperator
