class qiskit.opflow.evolutions.EvolutionBase[source]#

Bases: ConverterBase, ABC

Deprecated: A base for Evolution converters. Evolutions are converters which traverse an Operator tree, replacing any EvolvedOp e with a Schrodinger equation-style evolution CircuitOp equalling or approximating the matrix exponential of -i * the Operator contained inside (e.primitive). The Evolutions are essentially implementations of Hamiltonian Simulation algorithms, including various methods for Trotterization.

Deprecated since version 0.24.0: The class qiskit.opflow.evolutions.evolution_base.EvolutionBase is deprecated as of qiskit-terra 0.24.0. It will be removed no earlier than 3 months after the release date. For code migration guidelines, visit https://qisk.it/opflow_migration.
