qiskit.opflow.evolutions.Suzuki
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.
Parameters
- reps (
int) – The number of times to repeat the expansion circuit. - order (
int) – The order of the expansion to perform.
__init__
__init__(reps=1, order=2)
Parameters
- reps (
int) – The number of times to repeat the expansion circuit. - order (
int) – The order of the expansion to perform.
Methods
