class Suzuki(reps=1, order=2)[source]¶

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.

__init__(reps=1, order=2)[source]¶

Parameters

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.

convert(operator)[source]¶

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

Parameters: operator (OperatorBase) – The SummedOp to evolve.
Return type: OperatorBase
Returns: The Operator approximating op_sum’s evolution.
Raises: TypeError – A non-SummedOps Operator is passed into convert.

property order¶
