Fixed points of commutative Lüders operations
Liu Weihua, Wu Junde
This paper verifies a conjecture posed in a pair of papers on the fixed point sets for a class of quantum operations. Specifically, it is proved that if a quantum operation has mut…

On Fixed Points of Lüders Operation
Liu Weihua, Wu Junde
In this paper, we prove that if is a finite commutative quantum measurement, then the fixed points set of Lüders operation is the commu…

On supremum of bounded quantum observable
Liu Weihua, Wu Junde
In this paper, we present a new necessary and sufficient condition for which the supremum exists with respect to the logic order. Moreover, we give out a new and much simpler repre…
