TrotterizationBase#

class qiskit.opflow.evolutions.TrotterizationBase(reps=1)[source]#

Bases: EvolutionBase

Deprecated: A base for Trotterization methods, algorithms for approximating exponentiations of operator sums by compositions of exponentiations.

Deprecated since version 0.24.0: The class qiskit.opflow.evolutions.trotterizations.trotterization_base.TrotterizationBase 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.

Attributes

reps#

The number of repetitions to use in the Trotterization, improving the approximation accuracy.

Methods

abstract convert(operator)[source]#

Convert a SummedOp into a ComposedOp or CircuitOp representing an approximation of e^-i*``op_sum``.

Parameters:

operator (OperatorBase) -- The SummedOp to evolve.

Returns:

The Operator approximating op_sum's evolution.

Raises:

TypeError -- A non-SummedOps Operator is passed into convert.

Return type:

OperatorBase
