Description

Let φA be a general quantum operation. An operator B is said to be a fixed point of φA, if φA(B)=B. In this note, we shall show conditions under which B, a fixed point φA, implies that B is compatible with the operation element of φA. In particular, we offer an extension of the generalized Lueders theorem.
