Suzuki

qiskit.opflow.evolutions.Suzuki(reps=1, order=2) GitHub(opens in a new tab)

Bases: TrotterizationBase

Deprecated: Suzuki Trotter expansion, composing the evolution circuits of each Operator in the sum together by a recursive “bookends” strategy, repeating the whole composed circuit reps times.

Detailed in https://arxiv.org/pdf/quant-ph/0508139.pdf(opens in a new tab).

Deprecated since version 0.24.0

The class qiskit.opflow.evolutions.trotterizations.suzuki.Suzuki 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).

Parameters


Attributes

order

returns order

reps

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


Methods

convert

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
