# PVQDResult¶

`PVQDResult(evolved_state, aux_ops_evaluated=None, times=None, parameters=None, fidelities=None, estimated_error=None, observables=None)`

Bases: `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.

## Methods

### combine

`PVQDResult.combine(result)`

Any property from the argument that exists in the receiver is updated. :type result: `AlgorithmResult`

:param result: Argument result with properties to be set.

**Raises**

**TypeError** – Argument is None

**Return type**

`None`
