Bases: [`qiskit.algorithms.time_evolvers.time_evolution_result.TimeEvolutionResult`](qiskit.algorithms.TimeEvolutionResult "qiskit.algorithms.time_evolvers.time_evolution_result.TimeEvolutionResult")
|
||
|
||
The result object for the p-VQD algorithm.
|
||
|
||
**Parameters**
|
||
|
||
* **evolved\_state** – An evolved quantum state.
|
||
* **aux\_ops\_evaluated** – 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** – The times evaluated during the time integration.
|
||
* **parameters** – The parameter values at each evaluation time.
|
||
* **fidelities** – The fidelity of the Trotter step and variational update at each iteration.
|
||
* **estimated\_error** – The overall estimated error evaluated as one minus the product of all fidelities.
|
||
* **observables** – The value of the observables evaluated at each iteration.
