qib.operator.field_operator.FieldOperatorTerm

class qib.operator.field_operator.FieldOperatorTerm(opdesc: Sequence[IFODesc], coeffs)

Bases: object

Field operator term in second quantization, e.g., \(\sum_{j,k} h_{j,k} a^{\dagger}_j a_k\).

Each summation index is associated with a field and the operator type (e.g., fermionic creation operator).
