VQDResult
class VQDResult
Bases: qiskit.algorithms.variational_algorithm.VariationalResult
, qiskit.algorithms.eigen_solvers.eigen_solver.EigensolverResult
Pending deprecation: 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The VQDResult class has been superseded by the qiskit.algorithms.eigensolvers.VQDResult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.
