CircuitQFI.convert(operator, params=None)[source]¶ - Parameters
operator (
OperatorBase) – The operator corresponding to the quantum state \(|\psi(\omega)\rangle\) for which we compute the QFI.params (
Union[ParameterVector,ParameterExpression,List[ParameterExpression],None]) – The parameters \(\omega\) with respect to which we are computing the QFI.
- Return type
OperatorBase- Returns
An operator whose evaluation yields the QFI metric tensor.
- Raises
ValueError – If
paramscontains a parameter not present inoperator.
