TrotterizationBase

TrotterizationBase(reps=1) GitHub(opens in a new tab)

Bases: qiskit.opflow.evolutions.evolution_base.EvolutionBase

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


Methods Defined Here

convert

abstract TrotterizationBase.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.

Return type

OperatorBase

Returns

The Operator approximating op_sum’s evolution.

Raises

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


Attributes

reps

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

Return type

int
