Bases: TimeEvolutionResult

The result object for the p-VQD algorithm.

Parameters

evolved_state (QuantumCircuit) – An evolved quantum state.
aux_ops_evaluated (list[tuple[complex, complex]] | None) – Optional list of observables for which expected values on an evolved state are calculated. These values are in fact tuples formatted as (mean, standard deviation).
times (list[float] | None) – The times evaluated during the time integration.
parameters (list[np.ndarray] | None) – The parameter values at each evaluation time.
fidelities (Sequence[float] | None) – The fidelity of the Trotter step and variational update at each iteration.
estimated_error (float | None) – The overall estimated error evaluated as one minus the product of all fidelities.
observables (list[list[float]] | None) – The value of the observables evaluated at each iteration.

Methods

combine

combine(result)

Any property from the argument that exists in the receiver is updated. :param result: Argument result with properties to be set.

Raises

TypeError – Argument is None
