class TrotterizationBase(reps=1)
A base for Trotterization methods, algorithms for approximating exponentiations of operator sums by compositions of exponentiations.
__init__
__init__(reps=1)
Initialize self. See help(type(self)) for accurate signature.
Methods
__init__([reps]) | Initialize self. |
convert(operator) | Convert a SummedOp into a ComposedOp or CircuitOp representing an approximation of e^-i*``op_sum``. |
Attributes
reps | The number of repetitions to use in the Trotterization, improving the approximation accuracy. |
convert
abstract 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
OperatorBase
Returns
The Operator approximating op_sum’s evolution.
Raises
TypeError – A non-SummedOps Operator is passed into convert.
reps
The number of repetitions to use in the Trotterization, improving the approximation accuracy.
Return type
int
