Suzuki

class Suzuki(reps=1, order=2)

Bases: qiskit.opflow.evolutions.trotterizations.trotterization_base.TrotterizationBase

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.

Parameters

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

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

Methods Defined Here

convert

Convert a SummedOp into a ComposedOp or CircuitOp representing an approximation of e^-i*``op_sum``.
