abstract CircuitQFI.convert(operator, params=None)[source]
Paramètres
• 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.

Type renvoyé

OperatorBase

Renvoie

An operator whose evaluation yields the QFI metric tensor.

Lève

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