Eigensolver¶
- class Eigensolver[source]¶
Bases:
ABC
Deprecated: Eigensolver Interface.
The Eigensolver interface has been superseded by the
qiskit.algorithms.eigensolvers.Eigensolver
interface. This interface will be deprecated in a future release and subsequently removed after that.Algorithms that can compute eigenvalues for an operator may implement this interface to allow different algorithms to be used interchangeably.
Deprecated since version 0.24.0: The class
qiskit.algorithms.eigen_solvers.eigen_solver.Eigensolver
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 interfaceqiskit.algorithms.eigensolvers.Eigensolver
. See https://qisk.it/algo_migration for a migration guide.Methods
Computes eigenvalues.
Whether computing the expectation value of auxiliary operators is supported.
