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.
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
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.
