Suzuki

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.

Attributes

Suzuki.order

returns order

Suzuki.reps

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

Methods

Suzuki.convert(operator)

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