PauliSumOp¶
- class PauliSumOp(*args, **kwargs)[source]¶
Bases:
PrimitiveOp
Deprecated: Class for Operators backed by Terra’s
SparsePauliOp
class.Deprecated since version 0.24.0: The class
qiskit.opflow.primitive_ops.pauli_sum_op.PauliSumOp
is deprecated as of qiskit-terra 0.24.0. It will be removed no earlier than 3 months after the release date. For code migration guidelines, visit https://qisk.it/opflow_migration.- Parameters
primitive – The SparsePauliOp which defines the behavior of the underlying function.
coeff – A coefficient multiplying the primitive.
grouping_type – The type of grouping. If None, the operator is not grouped.
- Raises
TypeError – invalid parameters.
