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.


  • 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.




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


TypeError – Argument is None
