class qiskit.opflow.evolutions.Suzuki(reps=1, order=2)

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.

Obsolète depuis la 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 no earlier than 3 months after the release date. For code migration guidelines, visit https://qisk.it/opflow_migration.

Paramètres:

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

• order (int) – The order of the expansion to perform.

Attributes

order

returns order

reps

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

Methods

convert(operator)

Paramètres:

operator (OperatorBase) – The SummedOp to evolve.

Renvoie:

The Operator approximating op_sum’s evolution.
