Suzuki

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.

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

Parameters:

• 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)

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

Return type:

OperatorBase
