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.
Attributes
order
Type: int
returns order
Return type
int
reps
Type: int
The number of repetitions to use in the Trotterization, improving the approximation accuracy.
Return type
int
Methods
convert
Trotter.convert(operator)
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
Returns
The Operator approximating op_sum’s evolution.
Raises
TypeError – A non-SummedOps Operator is passed into convert.
