Characterization of affine automorphisms and ortho-order automorphisms of quantum probabilistic maps
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 call…
