class Suzuki(reps=1, order=2)

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.

パラメータ

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

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

__init__(reps=1, order=2)

パラメータ

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

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

Methods

__init__([reps, order])	type reps int
convert(operator)	Convert a SummedOp into a ComposedOp or CircuitOp representing an approximation of e^-i*``op_sum``.

Attributes

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