qiskit.aqua.operators.converters.AbelianGrouper¶

class
AbelianGrouper
(traverse=True)[código fonte]¶ The AbelianGrouper converts SummedOps into a sum of Abelian sums.
Meaning, it will traverse the Operator, and when it finds a SummedOp, it will evaluate which of the summed subOperators commute with one another. It will then convert each of the groups of commuting Operators into their own SummedOps, and return the sumofcommutingSummedOps. This is particularly useful for cases where mutually commuting groups can be handled similarly, as in the case of Pauli Expectations, where commuting Paulis have the same diagonalizing circuit rotation, or Pauli Evolutions, where commuting Paulis can be diagonalized together.
 Parâmetros
