class TrotterizationBase(reps=1)

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

__init__(reps=1)

Initialize self. See help(type(self)) for accurate signature.

Methods

__init__([reps])	Initialize self.
convert(operator)	Convert a SummedOp into a ComposedOp or CircuitOp representing an approximation of e^-i*``op_sum``.

Attributes

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

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.

Return type

OperatorBase

Returns

The Operator approximating op_sum’s evolution.

Raises

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

property reps

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

Return type

int
