Operator.reverse_qargs()[source]¶ Return an Operator with reversed subsystem ordering.
For a tensor product operator this is equivalent to reversing the order of tensor product subsystems. For an operator \(A = A_{n-1} \otimes ... \otimes A_0\) the returned operator will be \(A_0 \otimes ... \otimes A_{n-1}\).
- Returns
the operator with reversed subsystem order.
