qiskit.opflow.evolutions.Trotter
class Trotter(reps=1)
Simple Trotter expansion, composing the evolution circuits of each Operator in the sum together reps times and dividing the evolution time of each by reps.
Parameters
reps (int) – The number of times to repeat the Trotterization circuit.
__init__
__init__(reps=1)
Parameters
reps (int) – The number of times to repeat the Trotterization circuit.
Methods
__init__([reps]) | type repsint |
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. |
