Bases: [`ConverterBase`](qiskit.opflow.converters.ConverterBase "qiskit.opflow.converters.converter_base.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.
