qiskit.opflow.gradients.NaturalGradient.convert

NaturalGradient.convert(operator, params=None)

Parâmetros

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

• params (Optional[Union[ParameterVector, ParameterExpression, List[ParameterExpression]]]) – The parameters we are taking the gradient with respect to. If not explicitly passed, they are inferred from the operator and sorted by name.

Retorno

An operator whose evaluation yields the NaturalGradient.

Levanta

• TypeError – If operator does not represent an expectation value or the quantum state is not CircuitStateFn.

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

• ValueError – If operator is not parameterized.
