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The VQDResult class has been superseded by the qiskit.algorithms.eigensolvers.VQDResult class.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
