qiskit.aqua.operators.evolutions.Trotter¶

class Trotter(reps=1)[source]¶

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__(reps=1)[source]¶

Parameters: reps (int) – The number of times to repeat the Trotterization circuit.

Methods

__init__([reps])

type reps: int

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.

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.

property order¶

returns order

Return type: int

property reps¶

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

Return type: int
