TaperedPauliSumOp
class qiskit.opflow.primitive_ops.TaperedPauliSumOp(*args, **kwargs)
Bases: PauliSumOp
Deprecated: Class for PauliSumOp after tapering
The class qiskit.opflow.primitive_ops.tapered_pauli_sum_op.TaperedPauliSumOp is deprecated as of qiskit-terra 0.24.0. It will be removed in the Qiskit 1.0 release. For code migration guidelines, visit https://qisk.it/opflow_migration(opens in a new tab).
Parameters
- primitive – The SparsePauliOp which defines the behavior of the underlying function.
- z2_symmetries – Z2 symmetries which the Operator has.
- coeff – A coefficient multiplying the primitive.
Raises
TypeError(opens in a new tab) – invalid parameters.
Attributes
INDENTATION
Default value: ' '
coeff
The scalar coefficient multiplying the Operator.

Returns
The primitive object.

Methods
assign_parameters
assign_parameters(param_dict)
Binds scalar values to any Terra Parameters in the coefficients or primitives of the Operator, or substitutes one Parameter for another. This method differs from Terra’s assign_parameters in that it also supports lists of values to assign for a give Parameter, in which case self will be copied for each parameterization in the binding list(s), and all the copies will be returned in an OpList. If lists of parameterizations are used, every Parameter in the param_dict must have the same length list of parameterizations.
Parameters
param_dict (dict(opens in a new tab)) – The dictionary of Parameters to replace, and values or lists of values by which to replace them.
Returns
The OperatorBase with the Parameters in self replaced by the values or Parameters in param_dict. If param_dict contains parameterization lists, this OperatorBase is an OpList.
