Characterization of affine automorphisms and ortho-order automorphisms
of quantum probabilistic maps    [PDF]

Zhaofang Bai, Shuanping Du

In quantum mechanics, often it is important for the representation of quantum system to study the structure-preserving bijective maps of the quantum system. Such maps are also called isomorphisms or automorphisms. In this note, using the Uhlhorn-type of Wigner's theorem, we characterize all affine automorphisms and ortho-order automorphisms of quantum probabilistic maps.
