class qiskit.algorithms.minimum_eigensolvers.VQEResult
Bases: VariationalResult, MinimumEigensolverResult
Variational quantum eigensolver result.
Attributes
aux_operators_evaluated
The aux operator expectation values.
These values are in fact tuples formatted as (mean, (variance, shots)).
cost_function_evals
The number of cost optimizer evaluations.
eigenvalue
The computed minimum eigenvalue.
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
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
