transfer_vertex_to_majorana

transfer_vertex_to_majorana(inter_op)

Map a TransferVertexOperator to a MajoranaOperator.

Parameters:

inter_op – the transfer-vertex operator to map.

Returns:

The mapped majorana operator.

---

Definition

This function decomposes the transfer-vertex operators in terms of the majorana operators as defined here.

Usage

>>> from qiskit_fermions.mappers.library import transfer_vertex_to_majorana
>>> from qiskit_fermions.operators import TransferVertexOperator
>>> inter_op = TransferVertexOperator.from_dict({((0, 0),): 1, ((1, 2),): 2, ((2, 1),): -2})
>>> maj_op = transfer_vertex_to_majorana(inter_op)
>>> print(format(maj_op.normal_ordered().simplify()))
