edge_vertex_to_fermion
edge_vertex_to_fermion(inter_op)
Map an EdgeVertexOperator to a FermionOperator.
Parameters
inter_op – the edge-vertex operator to map.
Returns
The mapped fermionic operator.
Definition
This function decomposes the edge-vertex operators in terms of the fermionic action operators as defined here.
Usage
>>> from qiskit_fermions.mappers.library import edge_vertex_to_fermion
>>> from qiskit_fermions.operators import EdgeVertexOperator
>>> inter_op = EdgeVertexOperator.from_dict({((0, 0),): 1, ((1, 2),): 2})
>>> fer_op = edge_vertex_to_fermion(inter_op)
>>> print(format(fer_op.normal_ordered().simplify()))
