qiskit.aqua.operators.gradients.CircuitGradient.convert

abstract CircuitGradient.convert(operator, params=None)[source]
Parameters

  • operator (OperatorBase) – The operator we are taking the gradient of

  • params (Union[ParameterExpression, ParameterVector, List[ParameterExpression], Tuple[ParameterExpression, ParameterExpression], List[Tuple[ParameterExpression, ParameterExpression]], None]) – The parameters we are taking the gradient wrt: ω If a ParameterExpression, ParameterVector or List[ParameterExpression] is given, then the 1st order derivative of the operator is calculated. If a Tuple[ParameterExpression, ParameterExpression] or List[Tuple[ParameterExpression, ParameterExpression]] is given, then the 2nd order derivative of the operator is calculated.

Return type

OperatorBase

Returns

An operator whose evaluation yields the Gradient.

Raises

ValueError – If params contains a parameter not present in operator.
