VQDResult

class qiskit.algorithms.VQDResult[source]

Bases: VariationalResult, EigensolverResult

Deprecated: VQD Result.

The VQDResult class has been superseded by the qiskit.algorithms.eigensolvers.VQDResult class. This class will be deprecated in a future release and subsequently removed after that.

Deprecated since version 0.24.0: The class qiskit.algorithms.eigen_solvers.vqd.VQDResult is deprecated as of qiskit-terra 0.24.0. It will be removed no earlier than 3 months after the release date. Instead, use the class qiskit.algorithms.eigensolvers.VQDResult.See https://qisk.it/algo_migration for a migration guide.

Attributes

aux_operator_eigenvalues

Return aux operator expectation values.

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

cost_function_evals

Returns number of cost optimizer evaluations

eigenstates

return eigen state

eigenvalues

returns eigen values

optimal_circuit

The optimal circuits. Along with the optimal parameters, these can be used to retrieve the minimum eigenstate.

optimal_parameters

Returns the optimal parameters in a dictionary

optimal_point

Returns optimal point

optimal_value

Returns optimal value

optimizer_evals

Returns number of optimizer evaluations

optimizer_result

Returns the optimizer result

optimizer_time

Returns time taken for optimization

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
