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The Eigensolver interface has been superseded by the qiskit.algorithms.eigensolvers.Eigensolver interface.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.

Obsolète depuis la 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 interface qiskit.algorithms.eigensolvers.Eigensolver. See https://qisk.it/algo_migration for a migration guide.

Methods

`compute_eigenvalues`	Computes eigenvalues.
`supports_aux_operators`	Whether computing the expectation value of auxiliary operators is supported.
