class QDrift(reps=1)

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.

パラメータ

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

__init__(reps=1)

パラメータ

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

Methods

__init__([reps])	type reps int
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.

convert(operator)

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

パラメータ

operator (OperatorBase) – The SummedOp to evolve.

戻り値の型

OperatorBase

戻り値

The Operator approximating op_sum’s evolution.

例外

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