<Class id="qiskit.opflow.evolutions.Suzuki" isDedicatedPage={true} github="https://github.com/qiskit/qiskit/tree/stable/0.24/qiskit/opflow/evolutions/trotterizations/suzuki.py" signature="Suzuki(reps=1, order=2)" modifiers="class">
|
||
Bases: [`TrotterizationBase`](qiskit.opflow.evolutions.TrotterizationBase "qiskit.opflow.evolutions.trotterizations.trotterization_base.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](https://arxiv.org/pdf/quant-ph/0508139.pdf).

||
<Admonition title="Deprecated since version 0.24.0" type="danger">
|
||
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](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.

|
||
|
||
### convert
|
||
|
||
<Function id="qiskit.opflow.evolutions.Suzuki.convert" signature="Suzuki.convert(operator)">
|
||
Convert a `SummedOp` into a `ComposedOp` or `CircuitOp` representing an approximation of e^-i\*\`\`op\_sum\`\`.
|
||
|
||
**Parameters**
|
||
|
||
**operator** ([*OperatorBase*](qiskit.opflow.OperatorBase "qiskit.opflow.operator_base.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*](qiskit.opflow.OperatorBase "qiskit.opflow.operator_base.OperatorBase")
|
||
</Function>
