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 in the Qiskit 1.0 release. For code migration guidelines, visit https://qisk.it/opflow_migration(opens in a new tab).


Attributes

reps

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


Methods

convert

abstract convert(operator)

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(opens in a new tab) – A non-SummedOps Operator is passed into convert.

Return type

OperatorBase
