VQDResult

class qiskit.algorithms.eigensolvers.VQDResult

Bases: EigensolverResult

VQD Result.

Attributes

aux_operators_evaluated

Return the aux operator expectation values.

These values are in fact tuples formatted as (mean, metadata).

cost_function_evals

Returns number of cost optimizer evaluations

eigenvalues

Return the eigenvalues.

optimal_circuits

The optimal circuits. Along with the optimal parameters, these can be used to retrieve the different eigenstates.

optimal_parameters

Returns the optimal parameters for each step

optimal_points

Returns optimal point for each step

optimal_values

Returns optimal value for each step

optimizer_results

Returns the optimizer results for each step

optimizer_times

Returns time taken for optimization for each step

Methods

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
