# QDrift¶

class QDrift(reps=1)[source]

Bases: qiskit.aqua.operators.evolutions.trotterizations.trotterization_base.TrotterizationBase

The QDrift Trotterization method, which selects each each term in the Trotterization randomly, with a probability proportional to its weight. Based on the work of Earl Campbell in https://arxiv.org/abs/1811.08017.

Parameters

reps (int) -- The number of times to repeat the Trotterization circuit.

Methods

 convert 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.

Return type

int
